Western media: new technology can use intelligent detection of cancer

researchers at Massachusetts General Hospital in the United States have developed a device that can quickly and accurately diagnose tumors and other diseases, and provide help to areas lacking the latest medical technology. The materials that Massachusetts General Medicine in the United States needs to further develop in the future mainly include lithium rich manganese based solid solution materials, lithium manganese phosphate, lithium manganese iron phosphate, lithium iron phosphate graphene composites. Researchers at the Institute have developed a device that can quickly and accurately diagnose tumors and other diseases, and provide help to areas lacking the latest medical technology

according to Spanish newspaper abesse on April 14, researchers published an article in the Journal of the National Academy of Sciences in the United States, introducing this intelligent based device. Using holographic technology, this device can obtain detailed microscopic images to digitally analyze the molecular composition of cells and tissues

researcher xizecastro, one of the authors of the article, stressed: we believe that this platform we developed can provide the basic features required for diagnosis at a very low cost

the platform is called digital diffraction diagnosis system (D3 system), which is to install an imaging component equipped with light-emitting diodes on ordinary intelligence and use its camera to record high-resolution image data. D3 system has a larger field of vision than traditional microscope, and can record the data of more than 100000 cells in blood or tissue samples in a single image

these data will be uploaded to a remote image processor for analysis through secure and encrypted cloud services, and the analysis results will soon be sent back to the medical point. In order to analyze tumors at the molecular level, it is necessary to label blood or tissue samples with beads combined with known cancer related molecules, and install the beads on the imaging components of D3 system

after image acquisition and data transmission, it is necessary to detect whether there are specific molecules in masonry cement gb/t3183 ⑵ 003 by analyzing the diffraction pattern generated by beads. The use of beads with different sizes and coatings can produce a unique diffraction trajectory, which is more convenient for detection. The numerical algorithm developed by the research team for D3 system can distinguish cells and beads, and analyze up to 10 megabytes of data in 0.09 seconds

in the pilot experiment of using D3 system to study cancer cell lines, the existence of tumor proteins was detected with excellent accuracy, and the wide field of vision allowed researchers to analyze more than 100000 cells at the same time

the research team analyzed the cervical biopsy samples of 25 women with abnormal Pap test results. Results the D3 system analysis can quickly and reliably divide the samples into three categories: high-risk, low-risk and benign, and the results are consistent with the traditional pathological examination

the analysis of lymph node fine needle biopsy samples by D3 system can accurately distinguish four patients, and their lymphoma diagnosis results are also confirmed by traditional pathological examination

combined with protein analysis, D3 system can be successful after improvement, and cutting-edge new materials are the key fields that lead the development direction of new material technology and promote the development of new industries, such as human papillomavirus. In these tests, the results can be obtained within one hour, and the cost of each test is only $1.8. This price is expected to continue to decline with the improvement of the system in the future

researcher Ralph wesleyder said: we hope D3 platform can improve the breadth and depth of cancer detection, and it is also feasible and sustainable in places with limited resources. (compiled/Su Jiawei)
