METHOD FOR DETERMINING CARDIAC CYCLES AND ULTRASONIC DEVICE

The present invention relates to the technical field of image processing, in particular to a method for determining a cardiac cycle and ultrasonic equipment. The method comprises: acquiring a cardiac ultrasound video; classifying the cardiac ultrasound video by using a section type recognition model to determine a section type of the cardiac ultrasound video; and processing the cardiac ultrasound video by using a systole and diastole recognition model corresponding to the section type to obtain the cardiac cycle corresponding to the cardiac ultrasound video. The model is used to process the cardiac ultrasound video to detect the corresponding cardiac cycle. Model detection can avoid the use of an electrocardiograph and simplify the detection of the cardiac cycle. Furthermore, real-time detection of the cardiac cycle can be realized during echocardiography.
