Purchasing Insight: Portable X-ray

Portable chest X-rays are the most common diagnostic exam in intensive care units. Having the ability to perform them at the bedside is extremely valuable, as there exists clear clinical evidence that the latest digital radiography (DR) detector portable X-ray units allow for portable exams to be performed in almost half the time previously required for computed radiography (CR) and film-based exams. Substantial point-of-care diagnostic advantages can be realized through mobile X-ray units equipped with digital flat panel detectors. This technology allows physicians to view radiographic images in a matter of seconds after exposure and offers improved patient care and a more streamlined workflow for clinicians. There also is often a 30 to 50 percent reduction in radiation dose with the newer technology. Pricing for portable X-ray systems varies, depending first on the technology segment (analog versus digital), then on the power rating of the unit's chassis, and finally on the type and size of flat panel detector that is associated with the system. Multiple sizes of flat panel detectors are available to be paired with mobile X-ray units. Larger panels are typically 14" × 17" while smaller panel detectors come in four common sizes—11" × 14", 8" × 12", 24 cm × 30 cm, and 25 cm × 30 cm. Although it is possible to use both larger and smaller panels in conjunction with one mobile X-ray unit, doing so will increase the price of the unit dramatically. Smaller panels are most often utilized in NICUs and for orthopedic imaging of extremities, while larger panels are used for most other portable X-ray exams, such as studies of the chest, hips, and abdomen. Although analog portable X-ray units require a modest investment, $40,000 to $80,000, as compared with their digital cousins, advances in flat panel detector technology have made digital systems coupled with flat panels the gold standard in most U.S. hospitals today. Hospitals with an existing analog system have the option to retrofit a detector, which typically costs $62,000 to $140,000 depending on the size and type of flat panel. New fully-digital portable X-ray units run about $125,000 to $235,000 depending on maximum power output options and type of detector selected. Regarding service and support, most organizations opt for full-coverage service plans that include tube, battery, and detector drop protection because of the high cost of repairing and replacing the flat panel detectors. Analog units may require only partial coverage, such as second-call or time and materials only agreements, because they often can be serviced by trained hospital biomedical engineering (BME) staff.

Is snap portable across other UNIX (example macOS)?

Yes, thanks to the stability of the Linux syscall interface, this is possible.One of Linus Torvalds' great commitments to Linux users is that the set of interfaces offered by the kernel is stable. Many people do not appreciate the value of this, or how challenging it is as a leader of an open project to achieve that commitment. Consider for example how unpredictable changes in the GNOME APIs are by contrast! When you hear about Linus getting intense on a mailing list, it's almost always because some committer to the kernel decided to change such an interface 'because they had a better idea'. Linus says you can innovate wildly INSIDE the kernel, but please do not break the 'userspace' apps which depend on existing syscalls.As a consequence of that stability it is possible for other kernels to offer the same syscalls, allowing apps built on Linux to run on those other kernels. One example of that is the Joyent Triton project, which offer Linux-compatible syscalls in containers on SmartOS (a descendent of IllumOS, a descendent of Solaris).A more widely known example is the new Linux subsystem in Windows.Of course, how many of the syscalls are offered, and how bug-for-bug compatible they are, is the real question. At least for now, there is not another environment where all the necessary syscalls are in place, because the ones snaps use are relatively new and deep in the way the kernel thinks about the things it manages.But they will certainnly come, in time, and I think snaps will thus be usable in a wide range of contexts.Which is very cool, patches welcome :)

Keeping Your Gym Members Safe with a Portable AED
Keeping Your Gym Members Safe with a Portable AED
Many gyms and health clubs provide state-of-the-art training and equipment to help their members lead long, strong lives. It's also important to make certain that these facilities have state-of-the-art safety equipment such as CPR supplies and a portable AED (automatic external defibrillator). Without the proper safety equipment, the risk of health club members' deaths greatly increases. In Massachusetts a woman died from sudden cardiac arrest and while an off-duty paramedic tried to revive her, he did not have the necessary equipment - namely a portable AED. Led by local legislators and the late woman's mother, the state now requires that every fitness center own an AED and have a trained user on duty during all staffed business hours. That is just one example of how a portable AED can combat such tragedies. Unfortunately, the cost of an automated external defibrillator (as low as $1,000) often times stops health clubs and gyms from providing these life-saving devices. With states now requiring portable AEDs, health clubs may be required to comply and provide the life-saving equipment even if it means negatively impacting the bottom line. Once finances are in order, purchasing a portable AED can be easy if you keep in mind the following steps: 1.Ensure that the company you are entrusting with your health equipment needs is supported by the Better Business Bureau. Look into the awards they've received - especially safety awards - as well as feedback from their current customers. Are they easy and friendly to work with? Do you feel they will be around for the long haul? Can you trust them with the health and safety of your members? 2.Make sure that your portable defibrillators come with a warranty to protect against any malfunctions. While many units are vigorously tested to ensure they are performing properly, you want to rest easy knowing a backup is available if you need it. 3.Look into a Loaner Program which allows for customers to receive an identical defibrillator unit to replace a unit that needs service or repair. Verify that your AED supplier will provide a loaner unit if your unit ever needs to be serviced, repaired or replaced. 4.Verify that the AED comes complete with everything you need to get started, including the device itself as well as a carrying case, electrodes, a battery, operations manual, training DVD and AED check card. Don't forget the aforementioned Warranty and Loaner Program. 5.Examine the various customer service offerings and see if they meet your needs. Do units come with a 30-Day Money Back Guarantee? What is the charge for shipping? Are there any additional products offered (either discounted or free-of-charge) that you can bundle with your order? 6.When an AED is available, proper training on how to use the device is a key component. The American Red Cross provides training in addition to other life-saving training such as CPR and first aid. According to the Red Cross, its "first aid, CPR and AED programs are designed to give you the confidence to respond in an emergency situation with skills that can save a life." Supporting the health and fitness of one's local community goes well above supplying cardio equipment and free weights. Gym and health club executives need to proactively ensure their members are safe at all times.

Noted Benefits of a Portable Dental Unit for Dentists
Noted Benefits of a Portable Dental Unit for Dentists
Did anyone think of a day when you would carry your telephone with you? But someone within the technology community did and now we have mobile phones. The story of computers is similar, with its miniature versions like laptops, tablets, and even smartphones.Humans have found their convenience in everything portable and miniature, because of the sole reason of easy accessibility. Owing to the advancement in technology, over the years every industry has invested in their portable equipment, even healthcare.Today in this article, we will share with you the benefits that a dentist can enjoy by using a portable dental unit.Why the need for a mobile dental unit?Firstly, a portable mobile dental unit has the same attributes or works in the same way as the normal dental chair equipment that you see at your dentist's chamber. It is just a miniature version so that it can be carried to the patients who are too old or critical to visit the hospital or the doctor.This is one of the major reasons, for the recent rising demand for mobile medical equipment. In a recent study, it has been projected that by 2050 the 65 and above population will reach the 83.7 billion mark in the USA alone. We can only imagine the figures globally. So portable equipment both dental and otherwise are a necessity for doctors who need to tend to the aged patients.Portable medical equipment comes in handy for medical professionals and doctors who are working in remote areas, ones that do not have the necessary equipment. It can be a great asset for programs like Doctors without Borders.Benefits of Portable Dental Unit with Compressor for a DentistThere are numerous benefits of having one's portable dental unit for patient care. We have listed a few below:Dental units and opening a clinic can be a costly affair for someone who is starting his/her career. Getting a portable unit helps the person to manage the operational cost which is cost-effective compared to setting up a dental clinic.It allows one to take care of their patients anywhere and anyplace, be its school, home, office environment, etc.Being portable allows one to reach out to more people and greatly helps in the promotion of the dental service that they are offering.It also benefits the patients as they get more personalized care for their oral and dental issues.Portable dental units come well equipped with all the necessary equipment, that even allows one to operate on the patients. It offers both preventive and restorative oral and dental health.These are just a few noted advantages of getting a portable dental unit, by someone who is in dental healthcare.As per a global study, around 2.3 billion people around the world suffer from oral and dental health conditions. In children, the figure comes up to more than 530 million approximately.So the world needs reliable and experienced dentists and quality dental equipment, which is mobile can help serve a greater percentage of people·RELATED QUESTIONDo teeth cleaning removes bad breath?Helo!Yes! Teeth cleaning helps you to get rid of bad breath and plaque build-up.Plaque build-up is one of the biggest causes of tooth decay and bad breath because it harbours smelly bacteria. Teeth cleaning can knock out both these problems.Cleaning your teeth is important!It is important to clean your teeth every day with a toothbrush that is in good condition. You should brush for a few minutes in a firm circular motion. Also, remember to brush your tongue.You should also floss every day. Flossing removes particles and plaque from areas between teeth that the toothbrush cannot reach. Floss gently but effectively. Get between each tooth.If the teeth have tight space, use a pick. These can slide in lower and remove particles.With proper cleaning, you will have a healthier mouth overall. If you still feel like the breath gets stinky too easily, then it could be the time for a teeth cleaning procedure.Though brushing and flossing works to keep the mouth clean and prevent cavities, plaque can still grow.If the plaque remains on the teeth for too long, it can turn into an even harder version of itself, tartar.You should visit a dentist for teeth cleaning procedure at least once a year, but two visits yearly are recommended. Using professional dental tools, the dentists would remove the plaque, tartar, and other harmful bacteria buildup that you cannot access with at-home care. Oral hygienists effectively clean the entire mouth, which can help you improve the bad breath. Simultaneously, with teeth cleaning you will have protection from other gum diseases, tooth decay, and tooth loss.To clean your teeth effectively and get rid of bad breath, I would recommend No Gap Dentist in Australia.

What Are the Parts and Functions of the Good Portable Dental Chair ?
What Are the Parts and Functions of the Good Portable Dental Chair ?
Dental chair led lightThe dental chair led light is used to illuminate the oral cavity or mouth of the patient sitting on the portable dental chair. This light is positioned 30-50 inches from the mouth of the patient. This is practiced so that the light does not shine in the patient's eyes and he/she might feel uncomfortable. Lights contain dimmer switches to adjust the intensity of light.Cup (or Disposable glass) HolderDisposable glasses/cups (preferably) kept on the holders, are used for the patients to take in water during the dental procedures (as he/she might feel uncomfortable with the blood or debris in the mouth), and then gargle and spit out in the spittoon bowl.Spittoon BowlA bowl or basin-like receptacle for the patient to spit saliva from the mouth during dental procedures. It is provided with a water pipe supply to clean the bowl and push them toward the drain.Air-Water SyringeIt is a dental device that supplies a focused stream of compressed air, water, or a combination of both. It is frequently used to clean a tooth surface during dental treatment.Bracket TableIt holds the hand instruments and other materials such as -cotton -cotton holders -cement mixes -diagnostic instruments, etc.Related article:Does the use of dental headlight cause any harm to your eyes?Does dental whitening lamp work ?·RELATED QUESTIONWhat is the process that dentists and doctors typically go through when buying new equipment?Most doctors I know abhor the task of compiling a list and shopping for dental equipment to support a new, remodeled, or upgraded facility. They fear being taken advantage of by unscrupulous salespeople who will over-equip their facilities with unnecessary components and products at the greatest reseller margins. I was counseled in the last days of dental school to not trust the dental equipment suppliers to act in my best interests.Much of the disconnect between dentists and equipment reps comes from the dichotomy of sales and marketing vs. a dentist's technical training, which is based on years of deductive reasoning.OK, so how do you shop for and make major dental equipment purchases? Gathering information and taking positive, goal-directed steps always help overcome the fear of dealing with the unknown. Let's start with some background information on the dental equipment manufacturing and sales process.Manufacturers of Broken Tooth Treatment equipment such as A-dec, Pelton & Crane, Sirona, Gendex, etc., design, develop, fabricate, assemble, ship, and market equipment. Some manufacturers have only one piece of equipment, but most major companies have several different products with multiple choices within each specific product type.Patterson, Sullivan-Schein, and the other independent dental supply companies resell manufacturers' equipment to you.My experience in this process has been that resellers cannot financially support and successfully sell a product unless their sales margin is at least 20 percent. The great and enduring manufacturers are able to find the proper balance between providing quality products to the end-user and supporting their reseller network with marketing, financial, and technical assistance.You cannot purchase equipment directly from a manufacturer that distributes through a reseller network. The assignment of sales proceeds would be an unpleasant and murky task if you had manufacturers' reps and resellers competing with one another to sell the same products within a region.Emergency Dental Clinic.

Une machine à rayons X 3D portable basée sur la technologie d'observation des étoiles pourrait bientôt également être utilisée pour détecter le cancer
Une machine à rayons X 3D portable basée sur la technologie d'observation des étoiles pourrait bientôt également être utilisée pour détecter le cancer
Une machine d'imagerie à rayons X portable utilisée pour suivre les étoiles à des millions de kilomètres de distance pourrait être développée pour détecter les cancers précof.Les appareils à rayons X 2D peuvent souvent manquer des signes de cancer jusqu'à ce que la maladie soit avancée, Mais les scanners 3D fournissent une image beaucoup plus complète et donnent une plus grande précision dans la détection des maladies. Contrairement aux appareils à rayons X 2D traditionnels grands et coûteux, ils sont portables-ce qui permet de prendre une radiographie dans le bureau d'un médecin généraliste. Cela rend les scans et la technologie moins chers à utiliser que les machines hospitalières lourdes. Faites défiler vers le bas pour la vidéoActuellement, la radiographie est la principale méthode d'imagerie utilisée dans le diagnostic des soins de santé et fournit une image 2D du corps du patient. Mais les images réalisées à l'aide de scanners à rayons X 2D ne parviennent pas seulement à être suffisamment détaillées pour un diagnostic précis, Les machines lourdes signifient que des voyages supplémentaires vers des unités spécialisées sont souvent nécessaires. Bien que les scanner CT offrent une imagerie 3D, ils sont tout aussi lourds et coûteux, et l'imagerie est souvent retardée en conséquence. Le nouveau scanner 3D, que l'Agence spatiale britannique dépense 1million pour développer, Sera basé sur la même technologie que celle utilisée pour étudier les étoiles et promet d'être peu coûteux. Cela est en partie dû au fait que l'appareil à rayons X Adaptix 3D est une ''machine miniaturisée'' qui permet aux patients d'obtenir des rayons X dans les cabinets de médecin généraliste, réduisant ainsi la demande de scanners hospitaliers. La machine comprend des émetteurs de terrain utilisés auparavant par des vaisseaux spatiaux appartenant à l'Agence spatiale européenne dans la cartographie des étoiles à l'aide de fibres à rayons X-un projet connu sous le nom de XMM Newton dans lequel le Royaume-Uni a joué un rôle majeur. Ils émettent également moins de 10% du rayonnement des tomodensitogrammes à faible dose et seulement un à 2% Du plus largement utilisé, scanner diagnostique à dose complète. Le professeur Tony Young, directeur clinique national de l'innovation du NHS Englands, a déclaré: ''L'utilisation de la technologie d'observation des étoiles pour détecter le cancer est exactement le type d'innovation avancée qui pourrait améliorer les soins aux patients en accélérant le diagnostic et en aidant à mettre en œuvre notre plan à long terme qui permettra d'économiser un demi-million Des vies. Selon le site Web du gouvernement britannique: «L'environnement spatial exigeant signifie que les investissements dans le secteur génèrent de nouvelles connaissances et innovations qui vont bien au-delà de l'industrie spatiale.

Apprentissage profond pour une surveillance améliorée du cancer du sein à l'aide d'un scanner d'échographie portable
Apprentissage profond pour une surveillance améliorée du cancer du sein à l'aide d'un scanner d'échographie portable
Environ 1 femme américaine sur 8 développera un cancer du sein invasif au cours de sa vie. C'est la deuxième cause de décès par cancer chez les femmes aux États-Unis L'imagerie par ultrasons est une technique d'imagerie médicale non invasive utilisée pour le dépistage du cancer du sein. Chez Insight, j'ai travaillé sur un projet de conseil avec une start-up locale qui a développé une plate-forme d'imagerie par ultrasons automatisée, portable et portable permettant aux utilisateurs d'effectuer une auto-surveillance de la santé des seins. Le but du projet est de détecter automatiquement les lésions malignes sur les images échographiques. Dans ce blog, Ill décrit comment ce projet utilise la segmentation pour détecter les lésions dans une image et la classification pour détecter si ces lésions sont bénignes ou malignes. Données pré-traitements Pour la tâche de segmentation, les radiologues ont dessiné des contours autour des lésions dans 240 paires d'images brutes. Les régions du contour ont été mises en évidence dans les images du masque (voir image ci-dessus). Pour la tâche de classification, j'avais des données à peu près équilibrées pour les cas bénins et malins. Avant d'utiliser les données brutes pour la formation, elles ont été prétraitées comme indiqué dans la figure suivante. Les images brutes ont été filtrées pour supprimer le bruit, puis le contraste dans les images a été amélioré. Comme l'ensemble de données était petit, une augmentation a été effectuée sur les images, comme le retournement horizontal de l'image, la rotation et d'autres déformations. Enfin, les images ont été recadrées à la même taille. SegmentationÉtant donné que quelques patients avaient plusieurs images dans l'ensemble de données, les données ont été séparées, par patient, en trois parties: entraînement (80%), validation (10%) et test (10%). Le modèle était un U-Net modifié et formé sur GPU hébergé par Amazon Web Services (AWS) instances EC2. La fonction de perte utilisée est illustrée dans la figure ci-dessous, avec A représentant la vérité du sol (masque étiqueté manuellement) et B représentant le masque généré par le modèle. Si le masque du modèle est complètement éteint, le rapport intersection/union est de 0. S'ils se chevauchent complètement, le rapport est de 1. L'image résultante (ci-dessous) montre la vérité du sol en bleu, avec le contour rouge généré par le modèle. Le graphique ci-dessous montre un résumé des résultats des tests. Le rapport moyen intersection/union est de 0. 74, ce qui signifie qu'en moyenne, 74% se chevauchent entre le masque cible et notre sortie de prédiction. Le rapport de base est de 0,06 et est calculé en supposant que le modèle ne fait que deviner au hasard. Dans ce cas, l'intersection est la moitié de la taille moyenne du masque, et l'union est la moitié de la taille de l'image entière. ClassificationLorsqu'un radiologue lit une image échographique, il identifie d'abord la région de la lésion dans l'image, puis examine à la fois la région de la lésion et les régions environnantes pour différents types de caractéristiques afin de prendre une décision. Ici, nous avons construit un modèle pour imiter ce processus. L'architecture du modèle pour la classification est illustrée dans la figure suivante. Comme il n'y avait pas de masque disponible dans l'ensemble de données de classification fourni, les masques ont été générés à l'aide du modèle dans l'étape de segmentation précédente. Les images brutes ont été passées à travers des couches convolutives afin que le modèle puisse apprendre un ensemble de filtres pour extraire les caractéristiques. Le masque a fourni la région d'intérêt et, après, il a traversé des couches convolutives avec le même nombre de filtres que la branche de l'image. Pour chaque filtre de la branche image, il y avait un filtre correspondant dans la branche du masque. Certains filtres dans la branche de l'image étaient importants pour extraire des caractéristiques de la région de la lésion, tandis que d'autres étaient importants pour extraire des caractéristiques de la région d'arrière-plan de l'image. Les filtres de la branche du masque peuvent être entraînés à pondérer ces deux régions différemment pour les caractéristiques apprises dans la branche de l'image. Ces deux informations ont été combinées et introduites dans des couches convolutives, puis des couches entièrement connectées, pour générer des résultats. Afin de voir ce que le modèle a appris après l'entraînement, nous l'avons alimenté avec un masque fixe et une image vierge avec un bruit blanc, comme le montre la figure suivante. Pour générer une image qui représentait les caractéristiques malignes apprises, nous laissons le modèle modifier l'image vierge afin que la probabilité de malignité soit maximisée (à près de 1). La figure suivante montre deux exemples des images générées à partir du modèle. À partir de ces images, nous pouvons observer quelques éléments: la région de la lésion et la région environnante contribuent à la classification. Les régions de la lésion sont plus importantes, car la plupart des caractéristiques sont concentrées à l'intérieur de ces régions. Nous pouvons voir que le modèle a recherché différentes fonctionnalités pour ces deux régions. Cela montre que le modèle a en effet appris où et quoi chercher dans les images. Les résultats de l'ensemble de données de test sont présentés dans la matrice de confusion suivante. Le modèle est optimisé pour le rappel afin de réduire le faux négatif. La précision des tests du modèle est 0. 79 et le rappel est de 0,85 sur les données de test. Dans ce projet, j'ai utilisé des techniques d'apprentissage en profondeur pour détecter automatiquement les régions de lésion et classer la lésion, ce qui peut avoir des avantages à la fois en termes de coûts et de gain de temps. Actuellement, les patients doivent prendre des rendez-vous avec des techniciens en échographie et des médecins, ce qui est à la fois long et coûteux. Afin de réduire les coûts, la combinaison de l'appareil et du mode peut réduire le processus manuel impliqué. Une estimation de la réduction du processus manuel peut fournir un livrable quantifié pour ce projet. L'équation utilisée pour estimer le processus manuel est illustrée comme suit: Le taux de classe positif est la prévalence du cancer du sein, qui est d'environ 12%. Le rappel peut être fixé à 1 en ajustant le seuil du modèle. Étant donné que le taux de classe dans la formation est différent du taux de prévalence, la précision du modèle est ajustée. Le pourcentage estimé est d'environ 26%, ce qui signifie que la combinaison de l'appareil et du modèle peut réduire 74% du coût pour les utilisateurs. Conclusions Le modèle d'apprentissage en profondeur développé dans ce projet peut détecter automatiquement des lésions dans les images échographiques. En combinant le modèle avec le scanner portable, il peut produire des images répétables et permettre aux utilisateurs de surveiller leurs changements de santé au fil du temps, en fonction de leur propre ligne de base, pour le bon diagnostic au bon moment. Qin Miao était boursier Insight Health Data Science en 2019. Il est titulaire d'un doctorat en bio-ingénierie. Chez Insight, il a construit des modèles d'apprentissage en profondeur qui peuvent détecter automatiquement les lésions sur les images échographiques.
