Problems solved by technology

At present, no reports on this aspect have been found in domestic and foreign literature, although the invention patent: omnidirectional M-mode cardiogram method and its system (its patent number is ZL98125713.5) solves the problem of reconstructing any number of directions from the two-dimensional cross-sectional image of the heart. The movement trajectory of a certain part of the cardiac structure captured online (or called the motion waveform diagram, that is, the omnidirectional M-mode cardiogram). size

Embodiment Construction

[0028] Such as Figure 1 to Figure 4 Shown, the preamble of the present invention is on the basis of producing " omni-directional M-type cardiogram " waveform, and obtains its cardiac pattern (that is motion locus) corresponding to a certain structure of the selected heart through analysis and calculation. speed and acceleration.

[0029] The detection method of velocity field and acceleration field of the present invention comprises the following steps:

[0030] 1. Select the grayscale (position)-time waveform diagram that can represent a specified part of a certain structure of the heart from the omnidirectional M-mode cardiogram;

[0031] 2. Open a window manually, and use a linear template to pick and measure motion waveform points representing a certain structure of the heart from top to bottom in this window, and move the linear template to form the trajectory of the position over time .

[0032] 3. Artificial singularity and outlier interventions are performed on ind...

Abstract

An equipment for detecting the speed field and acceleration field of omnibearing M-type cardiogram is composed of omnibearing M-type cardiogram system, margin extracting module, containing linear module, speed generating module and acceleration generating module. Its method includes choosing an omnibering M-type cardiogram of a relative part of heart, extracting its margin, performing time differentiation to obtain the moving speed of said part, and performing time differentiation to obtain its acceleration.

Description

technical field [0001] The invention relates to a detection method and a device of a velocity field and an acceleration field, in particular to a detection method and a device of a velocity field and an acceleration field of an omnidirectional M-mode cardiogram. Background technique [0002] The detection method and device of the velocity field and the acceleration field of the omnidirectional M-mode cardiogram are used to detect the movement speed and acceleration of each structure, each part, and each moment of the heart, thereby further revealing the movement and deformation of each structure in the heart. At present, no reports on this aspect have been found in domestic and foreign literature, although the invention patent: omnidirectional M-mode cardiogram method and its system (its patent number is ZL98125713.5) solves the problem of reconstructing any number of directions from the two-dimensional cross-sectional image of the heart. The movement trajectory of a certain...
