The present disclosure relates to a system for measuring the cardiac cycle by using ultrasound images, which includes: an acquisition module for acquiring continuous multi-frame ultrasound images and presetting multiple estimated heart rate values. Internal acquisition; the selection module is configured to obtain multiple estimated cycles based on each estimated heart rate value, each estimated cycle is used as a target cycle, and multiple frames of ultrasound images are divided into multiple image groups based on the target cycle and a predetermined frequency, and selected The images of corresponding positions in each image group form multiple image sequences; the calculation module is configured to calculate the similarity of two adjacent frames of images in each image sequence and obtain multiple similarity values, and calculate the average value of multiple similarity values as the target The effective similarity value corresponding to the cycle is compared with the effective similarity value corresponding to each estimated cycle, and the cardiac cycle is obtained based on the estimated cycle corresponding to the largest effective similarity value. In this case, the cardiac cycle can be obtained more accurately.
Description
technical field [0001] The present disclosure specifically relates to a system and method for measuring cardiac cycle using ultrasound images. Background technique [0002] Cardiovascular disease has become the leading cause of death worldwide (eg, coronary heart disease). Currently, blood vessels are diagnosed and monitored by ultrasonic imaging of blood vessels through an ultrasound imaging system (such as an IVUS system). During ultrasound imaging, movement of tissues or organs (for example, respiration, heartbeat, etc.) may cause artifacts in the ultrasound imaging system, thereby degrading the quality of the acquired ultrasound image. [0003] In order to obtain higher-quality ultrasound images, techniques such as ECG gating are generally used to correct the collected ultrasound images. When using electrocardiographic gating technology to correct an ultrasound image, it is often necessary to obtain the heart rate value or cardiac cycle of the imaging subject during im...
