Description

Technical Field

[0001] The present invention relates to the technical field of electrocardiogram data acquisition systems, and in particular to a real-time electrocardiogram data acquisition system based on optical communication and used for CT / MRI equipment. Background Art

[0002] When CT / MRI scans the heart and its coronary arteries, the heart is always beating, and images of different beating intervals of the heart are collected during the scanning process. When the computer reconstructs the three-dimensional image, blur and artifacts will appear. This is the biggest limitation of heart scanning. In addition, X-rays are harmful to the human body. Minimizing the radiation dose received by patients during CT scanning is also one of the problems that CT equipment manufacturers need to work hard to solve.

[0003] In response to these two problems, CT equipment manufacturers have collected patients' real-time electrocardiograms (ECGs) to find the TP segments with relatively slow movements in the heart beat cycle and trigger CT scans, thereby effectively solving the above two problems. However, the real-time ECG data acquisition system currently used has many shortcomings, which limit its effectiveness in practical applications: 1. The delay is large, which brings large errors to the setting of the scanning window; 2. The system is powered by the power grid, which brings the risk of electric shock to patients; 3. The ECG acquisition module is connected to the CT / MRI host by cables, which will introduce a lot of interference, making it difficult or even wrong to extract effective information from the ECG signal; for problem 3, a few manufacturers have also adopted radio frequency communication with the host, but this method also has great limitations: 1. It will interfere with the patient's pacemaker, 2. It will interfere with the CT / MRI equipment, and 3. The radio channels available are strictly limited.

[0004] Therefore, a real-time ECG data acquisition system based on optical communication for CT / MRI equipment is proposed. Summary of the invention
