Abstract： |
The present invention belongs to the field of medical ultrasonics. The method of detecting myocardial blood supply state includes: establishing the mapping list between the back scattering integral fluctuation and the color; scanning the tested heart and acquiring continuously the ultrasonic RF signal to re-constitute B-mode image sequence reflecting the structure of the scanned area; selecting in the first frame interested rectangular area and marking the pixels representing cardiac muscle; tracing the marked point positions in different frames via image correlating process and finding out RF signal section corresponding to different times to calculate back scattering integral curve; calculating the back scattering integral fluctuation of the myocardial particles, and obtaining the blood supply state diagram of the myocardial particles via combining with the mapping list. The method can distinguish effectively normal cardiac muscle and ischemic cardiac muscle accurately. |
