A DSA imaging system has the following structure:
X-ray generator; The image acquisition department; Image processing department; Display department. Thanks to this method, doctors can soon detect abnormal blood flow conditions, help diagnose and treat diseases related to blood circulation accurately, and plan surgery, accurately identify locations. hurt mind. Therefore, most cases of cardiovascular disease, especially myocardial infarction, are diagnosed and treated promptly;
