Release date: 2017-08-15 In a recent "human-machine war", the medical imaging artificial intelligence analysis system "Alpha Doctor" developed by the joint research team of Shanghai Jiaotong University and Zhejiang University, and a video surgeon at a top three hospital competed with magnetic resonance imaging for rectal cancer. Identify accuracy and speed. As a result, "Alpha Doctor" is slightly better in accuracy, and far faster than doctors in speed. Can this artificial intelligence system enter the hospital and become an auxiliary diagnostic device? Researchers have given negative answers. Why is this?

The fully automatic image measurement instrument is an artificial intelligence modern optical non-contact measurement instrument developed on the basis of the digital image measurement instrument (also known as CNC image instrument). The fully automatic image measuring instrument inherits the excellent motion accuracy and motion control performance of digital instruments, integrates the design flexibility of machine software, and belongs to the forefront of optical size detection equipment today.
The full-automatic anime image measuring instrument is based on the CCD digital image, relying on the computer screen measurement technology and the powerful software capability of spatial geometry operation. After installing specialized control and graphic measurement software, the computer becomes the measurement brain with the soul of the software and is the main body of the entire device. It can quickly read the displacement value of the optical ruler and obtain the desired result instantly through software module operations based on spatial geometry; And generate graphics on the screen for the operator to compare the images and images, so as to visually distinguish possible deviations in the measurement results. All of this is done in real-time in front of powerful computer computing power, and the operator himself cannot detect it. This kind of precision instrument that can use CCD digital image, through computer software operation, to meet the needs of complex measurement is the real image measuring instrument, anime.
The fully automatic image measuring instrument has a wide range of applications in precision electronics, wafer technology, cutting tools, plastics, precision parts, springs, stamping parts, connectors, molds, military industry, two-dimensional reading, drawing, engineering development, hardware and plastic, PCB board, conductive rubber, powder metallurgy, screws, clock parts, mobile phones, pharmaceutical industry, fiber optic devices, automotive engineering, aerospace, higher education institutions, research institutes, and other fields.

Yan Weixin, Ph.D., of the Institute of Robotics, School of Mechanical and Power Engineering, Shanghai Jiaotong University, said that he collaborated with Niu Tianye, a professor at Zhejiang University's Institute of Translational Medicine, and Liao Huanhua, former director of the Tencent Data Platform Department, to build a machine learning model using the “regional convolutional neural networkâ€. The Shaoyifu Hospital affiliated to Zhejiang University School of Medicine and the Ruijin Hospital affiliated to Shanghai Jiaotong University School of Medicine provided them with tens of thousands of rectal cancer MRI images, all of which were sketched by doctors. After the research team “fed†the image data to the learning model, after more than 100,000 iterations, “Alpha Doctor†has the ability to accurately recognize rectal cancer, and can perform three-dimensional reconstruction based on images to provide a three-dimensional model of the tumor for doctors.
At the recent meeting of the China Medical Equipment Association, "Alpha Doctor" took only 23 seconds to complete the rectal cancer lesions of 300 MRI images. Compared with the pathological sections, the accuracy rate was 95.22%. Three imaging doctors in a top three hospital that competed with it completed 149 image maps in 5 minutes with an accuracy rate of 93%.
The Jiaotong University and Zhejiang University team are also cooperating with the Ninth People's Hospital affiliated to Jiaotong University Medical College to allow "Alpha Doctor" to identify and diagnose six skin diseases such as hemangioma based on digital images, with an accuracy rate of over 99%.
However, after the research team communicated with the doctor, they learned an embarrassing reality: According to the current regulations, “Alpha Doctor†could not enter the hospital. There are two reasons: First, the medical image analysis system based on artificial intelligence technology is not in the medical device directory of China. Therefore, “Alpha doctor†may not be able to obtain the medical device registration certificate, and therefore cannot be listed for sale. Second, even if it can be sold, The “Artificial Intelligence Reading Fee†is not included in the list of medical treatment charges, and many hospitals have no incentive to purchase such “robot doctorsâ€. How to promote the use of high-quality "robot doctors" at all levels of hospitals to improve the accuracy and efficiency of clinical diagnosis and treatment, and all parties need to work hard to break the problem. 
The accuracy of artificial intelligence rectal cancer reading is more than the doctor "Alpha" can not be treated
