Deep Learning for Improved Breast Cancer Monitoring Using a Portable Ultrasound Scanner
Deep Learning for Improved Breast Cancer Monitoring Using a Portable Ultrasound Scanner
About 1 in 8 U.S. women will develop invasive breast cancer during their lifetimes. Its the second leading cause of cancer death for women in the U.S. Ultrasound imaging is a noninvasive medical imaging technique used for breast cancer screening. At Insight, I worked on a consulting project with a local start-up company that developed an automated, portable, and wearable ultrasound imaging platform allowing users to perform self-monitoring of breast health. The goal of the project is to automatically detect malignant lesions in ultrasound images. In this blog, Ill describe how this project uses segmentation to detect lesions in an image, and classification to detect whether those lesions are benign or malignant. Data pre-processingFor the segmentation task, radiologists drew contours around the lesions in 240 pairs of raw images. The regions within the contour were highlighted in the mask images (see image above). For the classification task, I had roughly balanced data for benign and malignant cases. Before using the raw data for the training, they were pre-processed as shown in the following figure.The raw images were filtered to suppress noise, then the contrast in the images was enhanced. Since the dataset was small, augmentation was performed on the images, such as horizontally flipping the image, rotation and other deformations. Finally, the images were cropped to the same size.SegmentationSince a few patients had multiple images in the dataset, the data were separated, by patient, into three parts: training (80%), validation (10%), and testing (10%).The model was a modified U-Net and trained on GPU hosted by Amazon Web Services (AWS) EC2 instances. The loss function used is illustrated in the figure below, with A representing the ground truth (manually labeled mask) and B representing the model generated mask. If the mask from the model is completely off, then the intersection/union ratio is 0. If they are completely overlapping, then the ratio is 1. The resulting image (below) shows the ground truth in blue, with the red contour generated by the model. The box plot below shows a summary of the testing results. The average intersection/union ratio is 0. 74, which means that, on average, theres 74% overlap between the target mask and our prediction output. The baseline ratio is 0.06, and is calculated by assuming the model is just randomly guessing. In this case, the intersection is half the size of the average mask size, and the union is half the size of the whole image. ClassificationWhen a radiologist reads an ultrasound image, he first identifies the lesion region in the image, then looks at both the lesion region and surrounding regions for different types of features in order to make a decision. Here, we built a model to mimic this process.The architecture of the model for classification is shown in the following figure. Since there was no mask available in the provided classification dataset, the masks were generated using the model in the previous segmentation step. Raw images were passed through convolutional layers so the model could learn a set of filters to extract features. The mask provided the region of interest and, after, it passed through convolutional layers with the same number of filters as the image branch. For each filter in the image branch, there was a corresponding filter in the mask branch. Some filters in the image branch were important in extracting features from the lesion region, while others were important in extracting features from the background region of the image. The filters in the mask branch can be trained to weight these two regions differently for features learned in the image branch. These two pieces of information were combined and fed into convolutional layers, then fully connected layers, to generate results.In order to see what the model learned after training, we fed it with a fixed mask and a blank image with white noise, as shown in the following figure. To generate an image that represented the malignant features learned, we let the model modify the blank image so that the probability of malignancy is maximized (to almost 1). The following figure shows two examples of the generated images from the model. From these images, we can observe a few things:Both the lesion region and surrounding region contribute to the classification.The lesion regions are more important, since most of the features are concentrated inside these regions. We can see that the model looked for different features for these two regions. This shows that the model indeed learned where and what to look for in the images.The results of the testing dataset are shown in the following confusion matrix. The model is optimized for recall in order to reduce the false negative. The testing accuracy of the model is 0.79 and the recall is 0.85 on test data.DiscussionIn this project, I used deep learning techniques to automatically detect lesion regions and classify the lesion, which can have both cost and time-saving benefits. Currently, patients must make appointments with ultrasound technicians and physicians, which is both time-consuming and costly. In order to reduce cost, combining the device and the mode can reduce the manual process involved. An estimation of the reduction in the manual process can provide a quantified deliverable for this project.The equation used to estimate the manual process is shown in the following:The positive class rate is the prevalence of breast cancer, which is roughly 12%. The recall can be set to 1 by adjusting the threshold of the model. Since the class rate in the training is different than the prevalence rate, the precision from the model is adjusted. The estimated percentage is about 26%, which means that combining the device and model can reduce 74% of the cost for users. ConclusionsThe deep learning model developed in this project can automatically detect lesions in the ultrasound images. By combining the model with the portable scanner, it can produce repeatable images and allow users to monitor their health changes over time, based on their own baseline, for the right diagnosis at the right time.Qin Miao was an Insight Health Data Science Fellow in 2019. He holds a PhD in bioengineering. At Insight, he built deep learning models that can automatically detect lesions in ultrasound images.Are you interested in working on high-impact projects and transitioning to a career in data?

Brief Analysis of the Current Development Status and Trend of Chinese Medical Device
Brief Analysis of the Current Development Status and Trend of Chinese Medical Device
  Author:MeCan Medical–ultrasound machine manufacturersAt present, the epidemic is still spreading globally, and international trade and economic growth have stalled. Although the exports of Chinese medical equipment remain stable as a whole, they need to be alert to relevant risks and challenges. The relevant person in charge of the Medical Institution Department of the Medical Insurance Chamber of Commerce pointed out that in the short term, due to the needs of epidemic prevention and immunity, the global market has increased its dependence on the supply chain of Chinese medical device.In the long run, the epidemic has become a catalyst for reshaping the global industrial structure. With the introduction of policies in various countries, international competition will intensify, and the competition between Chinese medical devices in the global market will be more intense.In terms of market risks, the global economic recovery will lower the ability of the international market to procure ordinary medical supplies. The surge in demand for epidemic prevention materials, coupled with the decline in the efficiency of the port work, has caused serious lag in the circulation of containers, bringing a sharp increase in international logistics costs, especially shipping. The rise in raw materials and labor costs, and the strengthening of the supervision of merchants by cross -border e -commerce platforms will further squeeze the export profits of the enterprise.In addition, due to international travel restrictions, it is difficult for engineers and sales staff to conduct promotion activities in overseas markets and after -sales service for some large -scale equipment exported equipment, and it is not conducive to market sales.Overseas market expansion also needs to focus on the impact of changes in international market regulations. For example, the European Union has implemented new medical device regulations (MDR) and in vitro diagnostic medical device regulations (IVDR), pay more attention to the clinical performance of the product, strengthen the traceability of medical device products, and pay attention to improving the transparency of patients.These will improve the management and restrictions on medical device products entering the European market accordingly, and put forward higher requirements for the industry's employees, which will bring about increased costs to Chinese export companies, extending certification cycle, and increasing compliance risks, etc. challenge.

  Author:MeCan Medical–ultrasound machine manufacturersThe enzyme missionary instrument is commonly known as the enzyme -linked immunohistic detection instrument. It can be simply divided into two categories: semi -automatic and fully automatic, but its working principles are basically the same. The core of its core is a color meter, that is, the color method is used to analyze the content of the antigen or antibody. Clinical examination, biology research, agricultural science, food and environmental science. Let me introduce the application of enzyme -linked immune detector in pesticides and food.1. Fast diagnosis of animal epidemic.The enzyme -linked immune analyzer adopts the enzyme -linked immune adsorption measurement method and the corresponding reagent with a qualitative or quantitative animal disease diagnosis. Such as: pork blue ear virus, swine fever virus, pig pseudo -rabies virus, pig pseudo -rabies virus GE protein, pig ring virus, pork type encephalitis virus, pig mouth hoof disease 3ABC protein, pig mouth hoof disease virus IgG, pork fine virus, chicken chicken, chicken Bird flu, blue tongue disease, white spot syndrome, cattle infectious pleural pneumonia, cattle plague, cotton acne, and sheep acne detection.Second, pesticide residues.Organic phosphorus pesticides are commonly used in agricultural production in my country. Common types include methylmine, dichlorvos, oxygen fruit, phosphorus, and enemies. Most of them are highly toxic pesticides. By reducing the activity of cholthyne enzymes in the body, delayed neurotoxicity is caused, thereby achieving the purpose of eliminating pests. The enzyme -linked immune detector can be used to detect the methamidine content contained in fruits and vegetables.Third, food safetyThe enzyme -linked immune analysis method uses the special nature of the antibody and the corresponding antigen to detect the antibody contained in the food based on this. The immune enzyme method is to use specific enzymes as detection tags and reaction catalysts. The use of this method can be used to effectively avoid using radioactive elements during the detection process, or to conduct orientation and quantitative analysis of the detected objects. , Chemical residue, edible oil testing, water and wine beverage analysis, condiments, edible pigment, etc.At present, more automatic enzyme -linked immune detectors can be used for qualitative detection and quantitative detection. The detection only takes a few hours. It not only reduces the labor intensity of laboratory personnel, but also greatly improves the accuracy and repeatability of the determination. This is conducive to the further commercialization of ELISA technology in detection and analysis.

How Does the Magnetic Pearl Nucleic Acid Extraction Extract Nucleic Acid and Where Is the Advantage?
  Author:MeCan Medical–ultrasound machine manufacturersAs one of the current effective epidemic prevention and control methods, nucleic acid extraction and testing are no stranger to everyone. Prior to this, the method of extracting the traditional nucleic acid was chemical cracking and cylindrical method. However, with the rapid development of gene diagnosis, genetically modified food detection, and personalized medical care, traditional nucleic acid extraction technology can no longer meet the needs of today's biotechnology. As a result, magnetic pearl nucleic acid extraction came into being.No. A commercialized reagent that used the magnetic bead method to extract DNA and successfully applied for patents in the United States appeared in 1998. The magnetic bead method first absorbs the free nucleic acid molecule to the surface of the magnetic particles by cracking the cells, while the protein and polysaccharides are left in the solution. Under the influence of the magnetic field, the magnetic particles are separated from the liquid to discard the liquid to eliminate the liquid Later, the purified nucleic acid molecules were obtained after being eluted.The magnetic bead method uses the principle of combining and dissipating the magnetic acid activity group with a magnetic granular activity group under certain conditions to avoid the loss of nucleic acid during the extraction process as much as possible, and it can also remove the interference substances in the specimen (such as hemoglobin The effects of bilirubin and lipid blood), obtain high -quality nucleic acid templates. With the development of magnetic bead method extraction technology, DNA extraction has really begun to achieve standardization, rapidness and automation.The kits based on the magnetic acid extractor of the Magnetic Pearl Method are also widely used. Nucleic acid extraction kit does not require any organic solvent and no need to repeat centrifugation. At present, it can extract high -quality DNA and RNA from full blood, serum, plasma, saliva, urine, feces, cerebrospinal fluid, tissue and cells, and shorter time. The recovery rate is higher. And it can be automated and uninvited through mechanical equipment.In addition, the principle of magnetic pearl method is safe and non -toxic, and does not use toxic reagents such as benzene and chloroform in traditional methods. Mainstream nucleic acid extraction methods at home and abroad.

  Author:MeCan Medical–ultrasound machine manufacturersThe nucleic acid extract instrument is a supporting nucleic acid extract reagent from the motion to complete the sample nucleic acid extraction work. In the detection of the new crown, nucleic acid extraction is a very important step. At present, the extraction principle of nucleic acid extract instruments on the market is mainly divided into two types: magnetic bead method and membrane adsorption method, of which magnetic bead method occupies the mainstream market. So, what is the extraction step of the magnetic pearl nucleic acid extract instrument?Step 1: Add samples to the cracking solution.Step 2: In the cracking solution, the rupture cells release the nucleic acid to the cracking solution to transfer the magnetic beads to the cracking solution step 3: Fully mix the nucleic acid to adsorb the specific package on the surface of the magnetic beads.Step 4: Repeat the surface of the magnetic beads to remove impurities such as the unnecessary nucleic acid, protein or salt that are not needed.Step 5: Move the magnetic beads into the eluing solution and mix it fully. The nucleic acid is falling off from the surface of the magnetic bead and dissolved into the elution buffer.The magnetic pearl nucleic acid extract instrument is matched with different types of magnetic pearl nucleic acid extract reagents, and multiple samples are operated at the same time, which automatically separate the extraction and purification DNA/RNA from multiple samples such as blood, cells, tissues, viruses. The instrument uses a special magnetic stick adsorption, transfer, and releases magnetic beads to achieve the transfer of sample/magnetic bead/nucleic acid, avoiding liquid treatment, and increasing the degree of automation.Nucleic acid detection, as an important means of screening of new crown virus screening, is expected to maintain a high position for a period of time at home and abroad. The corresponding nucleic acid extract will be very strong in a considerable period of time. The operation is automated, fast, and simple, which provides a strong guarantee for the detection of new crown nucleic acid.

  Author:MeCan Medical–ultrasound machine manufacturersNucleic acid extraction instrument is an instrument that uses a supporting nucleic acid extract reagent from the motion to complete the sample nucleic acid extraction work. It is widely used in various fields such as disease control centers, clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial testing, food safety testing, animal husbandry and molecular biology research. In fact, with the normalized management of the epidemic, the nucleic acid extract instrument, as one of the commonly used equipment tested by various hospitals, has a higher frequency and the number of purchases has continued to rise. In fact, although everyone is familiar with the term of the nucleic acid extract instrument now, but it is very familiar with the term, but it is very familiar with the term of the nucleic acid extract instrument, but it is very familiar with the term, but it is very familiar with the term. I do nt know how to work and test the method of working principles. Let s take a closer look at the editor of Prank Medical Equipment.There are many classifications of nucleic acid extract instruments. In fact, the most commonly used is magnetic bead method. How does this method work? Magnetic pearl nucleic acid extract instrument is generally divided into two types: suction method and magnetic stick method. The specific operation process is as follows:First, suction method. The extraction of nucleic acids is achieved by fixed magnetic beads and metastasis liquids. Generally, the transfer of the robotic arm is generally controlled by the operating system.1. Crack. Add a cracking solution to the sample to achieve mixing and adequate reactions of the reaction solution through mechanical exercise and heating, cell cracks, and release nucleic acids.2. Adsorption. Add magnetic beads to the sample cracking solution and mix it in full. Use magnetic beads to adsorb nucleic acid under high salt and low pH value. Under the action of magnetic fields, the magnetic beads are separated from the solution. Mo the liquid out of the waste liquid tank and abandon the head.3. Washing. Remove the external magnetic field, add the new suction head to add the washing buffer, mix it fully, remove the impurities, and remove the liquid out of the magnetic field.4. Requesting. Withdrawing the magnetic field and adding the new suction head to add the elution buffer, fully mixed, the combined nucleic acid is separated from the magnetic bead, so as to obtain a purified nucleic acid.Second, magnetic stick method. By fixed liquids, the magnetic acid is separated to achieve the separation of nucleic acids. The principle and process are the same as the pumping method. The difference is the method of separation of magnetic beads and liquids. The magnetic stick method is to separate the magnetic beads from the waste liquid through the adsorption of the magnetic rod to the next step to achieve the extraction of nucleic acid.In fact, the characteristics of this magnetic pearl nucleic acid extract instrument is that it can achieve automation, high -throughput operations, safe and reliable operations, high efficiency, and pollution -free. Therefore, it is recognized by many buyers. When choosing a nucleic acid extraction instrument equipment, no matter which type of device is selected, you must have a basic understanding of it. You cannot judge the quality of the product from the price alone. For more product details, you can consult: 400-6656 -888.
