Abstract

The invention relates to a free M-type ultrasonic imaging system and method; the steps are as follows: S1: type B image is obtained by ultrasonic signal processing; S2: type B images are screened to capture ultrasonic B-type image frames of a customized sampling line selected by the user, and the extreme coordinate data of the customized sampling line of type B images are generated to generate M-type line data; S3: the coordinates of each point of the M-type line data is interpolated according to the endpoint coordinates of the customized sampling line on the current frame image; S4: forward and backward motion vector fields are interpolated according to the coordinates of all points on several M-shaped lines of the images in previous frame; S5: forward and backward motion vector fields are compensated after removing abnormal values and smoothing them; S6: the length of M-shaped line is interpolated after bilinearly interpolating the compensated forward and backward motion vector fields. The free M-type ultrasonic imaging system obtains free M-type ultrasonic images more efficiently and sets various parameters of free M-type ultrasonic imaging according to the requirements of users.

Description

technical field [0001] The invention relates to a free M-mode ultrasonic imaging system and method, and belongs to the technical field of ultrasonic imaging systems and methods. Background technique [0002] Free M-mode imaging technology is a relatively new technology in existing ultrasound imaging. Conventional M-mode imaging is based on a real ultrasound scan line, while free M-mode imaging is based on customizing virtual straight lines or curves on two-dimensional ultrasound images, and free M-mode imaging is essentially another form of expression of a two-dimensional ultrasound image sequence. Conventional ultrasound B-mode imaging can provide more complete spatial information, but M-mode imaging is more accurate in clinical evaluation of cardiac chamber size and cardiac function. Among the existing conventional M-mode ultrasound, some are suitable for high-frequency equipment, and some are suitable for low-frequency equipment. Now it is necessary to invent a free M-mo...
