These days, people are wondering about the evolution of the latest version of the "Alpha Dog." Because it took only 3 days, 4.9 million sets of self-taught training data, a machine and 4 TPUs defeated AlphaGo who defeated South Korean chess player Li Shishi.
With the development of AI (artificial intelligence), various industries are trying to introduce.
Recently, a "human-computer war" was held at the Sixth People's Hospital of Shanghai. Eighty-eight doctors played against the No. 9 player - the artificial intelligence reading system. The content of the game is based on the nature of the thyroid nodule ultrasound image. Among the 80 doctors participating in the competition, there are professors from the top three hospitals, young doctors from the first- and second-tier hospitals, and students from the medical school. The "artificial intelligence player" they are going to play against is a computer-assisted detection system for thyroid ultrasound.
According to reports, this is currently the world's first and only thyroid ultrasonic intelligent auxiliary diagnostic system through the United States Drug Administration (FDA), the European Union CE certification of marketing approval, in July this year, China's Food and Drug Administration has obtained marketing approval. The system utilizes patented image analysis technology to visualize, label and quantify tumor features in thyroid ultrasound images to assist physicians in accurate diagnosis and provide a non-invasive examination for thyroid cancers with increasing morbidity.
澎湃 News () reporters saw on the scene that every player participating in the “human-computer wars†holds a clicker, and each clicker has 3 buttons, which represent “possible vicious, uncertain, and benign possibleâ€. The doctor needs to make a judgment within 30 seconds based on the thyroid B-mode image displayed on the big screen. At the same time, AI will make a choice.
"Countdown 30 seconds to prepare, start! Ask the doctor to read the film, please AI (artificial intelligence) to read the film! Well, we look at the pathological results." This has already had pathological results of the examination, a total of 33 sets. In the end, artificial intelligence players ranked second among all competition players, and the accuracy of readings reached 84.85%. Prof. Lu Guorong, an ultrasound diagnostician from Fujian Province, won the first place and the accuracy rate of readings reached 87.88%.
“Professor Lu Guorong finally defeated the AI, which made us very excited. Of course, the performance of the AI ​​also made doctors feel the pressure. From the current point of view, AI is only to assist the doctor's diagnosis, because the correctness of software diagnosis is closely related to the correct outline of the mass, B ultrasound doctors usually explore and judge in dynamic images, and have to combine with other clinical manifestations. This game is equal to using our 18 weapons as a waste of 17 samples, leaving only the same strong data analysis as the computer's “Taipei Xianâ€. It is not fair to compete and it is important to know that the correct rate of diagnosis of thyroid nodules by doctors is very high if multi-faceted, multi-modal, etc. are used,†said an expert during the post-game comment period.
"Artificial intelligence can't replace doctors. In most cases, it can only be used as an auxiliary measure." Wang Yan, chief physician of the Department of Ultrasound at City Six Hospital pointed out that there are many different aspects of ultrasound diagnosis, and many other factors need to be considered. However, artificial intelligence can only look at one aspect and is not comprehensive enough. However, the advantages of artificial intelligence big data analysis can be used as a means to assist young doctors at the grassroots level and community screening. This is also a general direction.
At present, the Ministry of Science and Technology's key research and development plan for digital medical equipment research and development focuses on the comprehensive evaluation and training program for medical ultrasound imaging systems based on multi-regional and different-level hospitals. It was officially launched at the Sixth People's Hospital of Shanghai. Professor Hu Bing, director of the Department of Ultrasound Medicine at the Six Hospital of Shenzhen City, introduced that ultrasound medicine is highly rigorous and complex. Therefore, the requirements for treatment planning, quality control and personnel level are also very high. How to solve the uneven level of the overall level of these aspects in China? To become a top priority, this is also the value of digital diagnostics and medical evaluation of medical ultrasound imaging systems.
