Problems solved by technology

Therefore, the scanning, pre-processing, and post-processing controlled by a real-time CPU clock, including DSC processing and smoothing video image processing system, simultaneously display conventional content, label information, algorithm processing and display required by each department, and image storage , playback, keyboard, etc. are also controlled by the CPU. Due to the heavy burden on the CPU, the real-time performance, reliability and compatibility of the entire system are poor, and there will be a crash phenomenon during normal work. The traditional B-ultrasound can only The price of connecting a video printer is generally more than 10,000 yuan, which is difficult for ordinary users to accept
