Embodiment Construction

[0025] Hereinafter, preferred embodiments of the present disclosure will be described in detail with reference to the drawings. In the following description, the same reference numerals are given to the same components, and repeated descriptions are omitted. In addition, the drawings are only schematic diagrams, and the ratio of dimensions between components, the shape of components, and the like may be different from the actual ones.

[0026] The system 10 (see figure 1 ) may measure, based on the ultrasound image, a cardiac cycle or heart rate value of the imaged subject at the time the ultrasound image was acquired. Through the system 10 for measuring cardiac cycle (or heart rate value) by using ultrasonic images involved in the present disclosure, more accurate cardiac cycle or heart rate value can be obtained.

[0027] The system 10 involved in the present disclosure will be described in detail below with reference to the accompanying drawings.

[0028] figure 1 It is...

Abstract

The invention relates to a system and method for measuring a heart rate value by using ultrasonic images. The system comprises an acquisition module which is used for acquiring a plurality of frames of continuous ultrasonic images and presetting a plurality of estimated heart rate values, wherein the ultrasonic images are generated at a preset frequency; a selection module, wherein the selection module is configured to take each estimated heart rate value as a target heart rate value, acquire a predetermined frame number based on the target heart rate value and the preset frequency, and select images at corresponding positions from the multiple frames of ultrasonic images based on the predetermined frame number to form a plurality of image sequences; and a calculation module, wherein the calculation module is configured to calculate the similarity of two adjacent frames of images in each image sequence and obtain a plurality of similarity values, calculate an average value of the plurality of similarity values as an effective similarity value corresponding to the target heart rate value, compare the effective similarity values corresponding to each estimated heart rate value, and obtain the heart rate value based on the estimated heart rate value corresponding to the maximum effective similarity value. Under the condition, the heart rate value can be relatively accurately obtained.

Description

technical field [0001] The present disclosure specifically relates to a system and method for measuring heart rate values ​​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 dur...
