| Abstract: | This paper introduces a programming cardiac trigger apparatus used for the study of quantitative measurement of myocardial blood flow with myocardial contrast echocardiography. The design of hardware circuit based on MCU and the scheme of software based on Keil C51 are mainly discussed. With stable and reliable working, this apparatus provides a kind of technical support for the study of quantitative measurement of myocardial blood flow with continuous intravenous injection of sonicated microbubbles. |
