Embodiment Construction

[0021] Such as figure 1 Shown in-5, the acceleration field detection method of tissue Doppler diagram in the color ultrasound of the present invention is as follows:

[0022] It includes any one or more of the following four methods, and the steps of each method are as follows:

[0023] (1) The first method

[0024] (a) extract the tissue Doppler color velocity map by the tissue Doppler velocity map extraction module,

[0025] (b) by step (a) through the color → black and white grayscale map conversion module of the tissue Doppler velocity map, converted into a black and white map,

[0026] (c) another routing step (a) through velocity, time conversion, calibration modules,

[0027] (d) by step (b) and (c) together again through the selection of the black-and-white gray-scale tissue Doppler velocity map with velocity and time mark,

[0028] (e) through the detection of the tissue Doppler special-purpose edge detection module, V=V(t) is obtained,

[0029] (f) through the a...

Abstract

The invention relates to a detecting method of tissue Doppler acceleration field and its device in color super technique, it is about abstracting rate curve V=V(t) in some position of the heart constructions from tissue Doppler velocity diagram, doing first-order differentiation to it and getting the detection of acceleration field of the acceleration a=a(t) in said position of the heart conditions. Said invention and its device could detect the acceleration field while moving in said potion at the base of getting the velocity diagram of heart constructions in some position in color super new tech tissue Doppler detection. According to Newton's second law F=ma, the detection of acceleration offers very important information to the forced situation in said position, therefore, it has very important values to homodynamic research in different positions of the heart construction and the diagnosis of cardiovascular diseases.

Description

Technical field: [0001] The invention relates to an acceleration field detection method and a device thereof, in particular to an acceleration field detection method and a device of a tissue Doppler image in a color ultrasound. Background technique: [0002] A relatively new technology in imported color Doppler ultrasound is the tissue Doppler map, which is the velocity field map of the heart structure tissue. It uses Doppler technology to detect the movement speed of a certain part of the heart structure in the direction of the ultrasonic beam at each moment. , we refer to it as the velocity field for short, and the speed of the country's published invention patent "Detection method and device for velocity field and acceleration field of omnidirectional M-mode cardiogram" (public number: CN1539379A; application number: 200310104284.0) field has a similar meaning. However, the acceleration field of the tissue Doppler velocity field, that is, the acceleration detection at ea...
