Method and system for automatically measuring structural angle in muscle tissue

Abstract

The invention discloses a method and system for automatically measuring a structural angle in muscle tissue, and the method comprises the steps: obtaining a muscle ultrasonic image in muscle contraction motion in real time, carrying out the preprocessing, and enhancing the edge information of the image; dividing fascia and muscular bundle areas in the muscle ultrasonic image by a called normalizedRadon transform algorithm, and obtaining a first included angle between the deep fascia and a preset horizontal axis; performing normalized Radon transformation on the muscle bundle area, extractinga plurality of peak points in a Radon transformation matrix, and performing weighted average on the positions and directions of all muscle fibers to obtain a second included angle between the muscle fibers and the horizontal axis; and performing summation calculation on the first included angle and the second included angle to obtain a structural angle in the muscle tissue, wherein the structuralangle is a muscle plume angle. According to the method, the structural angle in the muscle tissue can be naturally, smoothly, robustly and automatically measured, so that the measurement result is closer to the real motion state, and the structural function of the muscle can be better reflected.

Description

technical field [0001] The invention relates to the technical field of measuring muscle structural angles, in particular to an automatic measuring method and system for structural angles in muscle tissue. Background technique [0002] Muscle is an important tissue that constitutes the human body, and its main function is to produce contraction and control body movement. Muscle structure has a major impact on the way muscle force is transmitted to tendons and bones. Muscle structural angles, such as muscle plume angle, are important indicators for skeletal muscle research. The angle of muscle structure is highly correlated with the intensity of muscle contraction, which can help doctors understand the biomechanical properties of muscles, better evaluate muscle function and pathological status, and provide an effective basis for clinical diagnosis and rehabilitation evaluation. [0003] At present, most of the measurement methods for structural angles in muscle tissue are ma...
