Cardiac Ultrasound Imaging Methods

Abstract

The invention discloses a cardiac ultrasound imaging method, and aims at solving the problem of automatically segmenting of a left ventricle contour during a cardiac measurement process, and preventing the situation of inaccurate volume calculation which might be caused by manually specifying left ventricular segmentation points in the measurement process. Compared with a traditional left ventricular segmentation algorithm, a large number of images of the position of a left ventricle manually marked by a doctor are used to train a deep convolutional neural network, the position of the left ventricle can be accurately identified by the acquired detection network, and a level set algorithm can be performed within a detection position area to obtain a segmentation curve of a left ventricularendocardium; compared with a traditional algorithm, acquired results are more robust, the operation efficiency is higher. According to the cardiac ultrasound imaging method, a manual enhancement manner is adopted to enhance edge areas to improve a segmentation effect aiming at the situation of poor image quality of ultrasound mapping.

Description

technical field [0001] The invention relates to the field of ultrasonic image processing, in particular to a cardiac ultrasonic imaging method. Background technique [0002] Two-dimensional real-time echocardiography is a non-invasive diagnostic and monitoring technique widely used in clinical diagnosis and treatment of cardiovascular diseases. Although accurate delineation of the intimal boundary of the left ventricle during diastole and systole can provide important cardiac function parameters for clinical practice, However, due to the quality of ultrasound images, it has always been very difficult to delineate ultrasound boundaries fully or even semi-automatically. [0003] At present, there are some left ventricle segmentation algorithms that use the level set method to obtain the segmentation curve of the left ventricle endocardium. The initial level set generated by the algorithm has low accuracy. Contents of the invention [0004] The purpose of the present invent...
