After several years of development, almost all of the top three hospitals across the country have appeared in the medical AI. Among them, Zhejiang is the most active region. Although there are not many medical AI companies in Zhejiang, many top three hospitals in Zhejiang Province are Embracing AI around 2016 and discussing the application and issues of medical AI at various medical conferences.
Last week, medical artificial intelligence appeared in many activities in Zhejiang, such as the 5th Qianjiang International Imaging Forum and the first promotion meeting of Zheng Caiyun. As the leading medical artificial intelligence company in China, Tuma Shenwei actively participates in academic and commercial exchange activities, displays its own research and development results, shares Tuma's understanding of the industry, and assists the development and application of medical artificial intelligence in Zhejiang Province.
Tumman, founder and CEO of Tuma Deep, made a theme sharing at the Qianjiang International Imaging Forum
The 5th Qianjiang International Image Forum was organized on the theme of “Building a Bridge of Medical Workers and Creating Smart Imagesâ€. The Forum also organized a special forum on artificial intelligence and information construction for the current hot issues in radiology.
Special guests at the conference included academician of the Chinese Academy of Engineering, executive vice president of Peking University, director of the medical department Zhan Qimin, director of the Chinese Medical Association Radiology Branch Jin Zhengyu, academician of the Chinese Academy of Engineering, and chairman of the Chinese Society of Neuroscience, Duan Shumin and other industry executives. Tumman, the founder and CEO of Tuma Deep, also brought the theme sharing - "On the artificial intelligence medical imaging", elaborated on the exploration and prospect of Tuma Deep in the smart medical industry , and the Imaging Department of Shanghai Pulmonary Hospital Professor Sun Xiwen made a live dialogue about medical AI.

Zhong Rong said that lung cancer is the world's highest malignant tumor with morbidity and mortality, accounting for 18% of all malignant tumor deaths. However, since about 75% of lung cancer patients in China are in advanced stage of diagnosis, the 5-year survival rate is only about 15.6%. The discovery, review and follow-up of pulmonary nodules can improve the rate of early lung cancer discovery and early treatment, thus improving the patient's recovery and quality of life.
Early screening for lung cancer is a good thing, but it is very cumbersome to implement. National radiologists' annual readings increase by 33%, but the number of radiologists is only 4%, and the number of radiologists is far from meeting the demand for reading. And reading is a meticulous job. Working in such a long time will affect the doctor's condition, and the doctor's working condition will affect the quality of the reading.
Take the Second Hospital of Zhangzhou as an example. The daily CT report of the radiology department of the hospital is about 400, of which chest CT accounts for 1/3, and 90% of the chest images have nodules.
For lung nodules, especially small nodules, doctors often need to spend more time looking at layers, but also to look back and forth several times to reduce missed diagnosis and misdiagnosis, but still can not guarantee 100% accuracy. Under the condition of limited energy and time, how to improve the speed and accuracy of reporting has always been a major problem for radiologists.
Tuma's products have become doctor's " trekking poles"
Tuma Deep has been developing automated medical diagnostic systems and medical data analysis systems based on artificial intelligence technology. Zhong Wei pointed out that the development of medical artificial intelligence has now blossomed, and there are more than 100 medical artificial intelligence companies with research results all over the world. Each product has its own fields in new drug discovery, medical imaging, gene sequencing data analysis, insurance and other fields. In-depth application.
Among them, medical imaging is the most mature field of development. 70% of domestic medical AI companies are involved in the field of medical imaging, and their products are promoted to hospitals across the country. Take Tuoma Shenwei as an example, the products have covered more than 100 hospitals nationwide.
The doctor's feedback is also very good. Professor Sun Xiwen from the Imaging Department of Shanghai Pulmonary Hospital said that since the department has been in contact with Tuma for more than a year, the speed of product improvement has been amazing. Previous doctors' knowledge of medical AI stayed on traditional CAD products that detected nodules, but false positives were too high, adding a lot of extra work to the doctor.
Tuma's products have good and malignant judgments, can directly detect the nature of the lesions, and actually help the doctor in practical work.
In addition, Professor Sun Xiwen said that there are many medical AI companies. He divided the company's medical imaging AI products into two categories, one is the auxiliary screening system, and the other is the auxiliary expert system. The auxiliary screening system can only detect nodules, assist the expert system with the strength of good and evil judgments like experts, and because of the stability and learning ability of AI, the system is constantly improving, in the daily work of the department, Tuma deep Victoria's products have become an indispensable tool like trekking poles.
Zhong Rong added that the σ-Discover-Lung lung nodule detection system of Tuma Deep has been used for sensitivity research in many well-known radiology centers in China. The total number of test samples was 77. The total number of samples used by AI doctors was 4.5 hours. The cumulative time of doctors without AI helped more than 10 hours. The system detected a total of 988 nodules, of which the detection rate of 3mm-4mm nodules. The highest, up to 97.92%, the false positive is extremely low, the lowest is only 0.25 per case.
Achieve full process diagnostic coverage
Tuma's products can not only achieve the assessment of malignant risks, but also achieve follow-up of nodule follow-up, treatment guidance, automatic generation of structured reports, and assist doctors in scientific research. According to these functions, the full-process diagnostic coverage can be realized.
Malignant risk assessment: Tuma deep-dimensional training based on more than 60,000 cases of data to obtain benign and malignant quantitative analysis techniques, and after more than 10,000 case data test, the accuracy of matching with pathological results exceeds 90%.
Nodular follow-up: As the thickness of the CT layer became thinner, the nodules that CT can screen were only 1-2 mm. Tuma's deep-dimensional products can achieve multiple simultaneous examinations of nodular patients, accurately comparing the growth of nodules before and after. In the process of loading, multi-nodule automatic registration, positioning, and comparison of parameters are displayed synchronously. And predict the doubling time and the nodules of the benign and malignant.
Treatment guidance: Tuma deep-dimensional products through 3D algorithm, accurate anatomical positioning, lung nodule segmentation, assessment of the relationship between nodules and surrounding tissue, assist surgeons surgical path and program development. Gradually move the product from diagnosis to treatment.
In addition, Tuma Deep is also conducting research on imaging omics, and improving the diagnosis of patients by integrating clinical information such as images, texts, and genes.
Zhong Rong finally said that Tuma's product line is a full-process diagnostic coverage of multiple parts of the human body. It will be actively promoted in many fields such as cancer, cerebrovascular and cardiovascular, and develop medical AI products for doctors' clinical needs.
