The main task is to save all kinds of medical images (including MRI, CT, ultrasound, various X-ray machines, various infrared instruments, microscopes, etc.) through various interfaces (analog, DICOM, network) in a digitalized way, so that they can be quickly recalled for use under certain authorization when needed, and at the same time, some auxiliary diagnostic and management functions are added.
