Embodiment Construction
[0026] The technical solution of the method and system for measuring muscle thickness based on ultrasound images will be described in detail below in conjunction with specific embodiments and accompanying drawings, so as to make it more clear.
[0027] Such as figure 1 Shown, in one embodiment, a kind of muscle thickness measurement method based on ultrasonic image comprises the following steps:
[0028] Step S110, extracting an image of interest from the ultrasound image.
[0029] In this embodiment, a real-time B-mode ultrasonic scanner and an electronic linear array probe are used to obtain ultrasonic images of muscles. Specifically, the long-axis direction of the ultrasonic probe was vertically arranged on the experimenter's thigh, and placed at about 40% of the long-axis distance from the knee. Apply plenty of ultrasound gel to ensure that the probe is acoustically coupled to the skin during muscle contraction, and adjust the probe to optimize contrast for visualization...

The invention discloses a muscle thickness measuring method and system based on an ultrasonic image. The method comprises the following steps of: extracting an interesting image from the ultrasonic image; acquiring the positions of a plurality of initial tracing windows selected in the interesting image; tracing the tracing windows, and determining the positions of a plurality of tracing windows which correspond to every frame of subsequent image through a tracing algorithm; processing tracing windows which are similar to the modes of surrounding images in the tracing windows of each frame of image by taking a diagonal intersection point as a central point, and processing other tracing windows in every frame of image by adopting an edge detection method; and computing a maximum vertical distance between the position of each tracing window processed by using the central point in every frame of image and the position of each tracing window processed through the edge detection method, wherein the maximum vertical distance is taken as a muscle thickness value. Due to the adoption of the muscle thickness measuring method and the muscle thickness measuring system based on the ultrasonic image, the measuring accuracy and measuring efficiency are increased, and the aim of measuring in real time is fulfilled.
Description
technical field [0001] The invention relates to the field of image processing, in particular to a method and system for measuring muscle thickness based on ultrasonic images. Background technique [0002] The mechanical properties of skeletal muscle are related to its structural shape. Any physical activity and sports are completed by the contraction of skeletal muscle, which directly affects the strength and endurance of the human body. Muscle has a certain degree of elasticity. After being stretched, it can automatically return to its original level when the tension is released. The elasticity of the muscle can slow down the impact of external forces on the human body, so it plays a vital role in sports. However, the composition of muscles is very complex. Quantitative analysis and evaluation of muscle function status are the difficulties and hot spots in the research of sports medicine and sports function rehabilitation. [0003] At present, most of the measurement of mu...
