Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic detection equipment, and in particular to a fixing device for collecting B-type ultrasonic signals of a human arm. Background Art

[0002] B-mode ultrasound is an ultrasonic imaging technology widely used in medical imaging. Its principle is based on pulse echo technology, which generates a two-dimensional image by emitting high-frequency sound waves to the target tissue and receiving the sound wave signals reflected from the tissue interface. The main feature of B-mode ultrasound signals is that its intensity represents the amplitude of the echo, while the delay time of the echo represents the tissue information at different depths. Specifically, the ultrasound probe emits sound waves after contacting the skin surface. These sound waves propagate inside the tissue and are partially reflected or transmitted when encountering the muscle or bone interface. After the reflected sound waves are received by the probe, they are converted into electrical signals, and through signal processing, a two-dimensional grayscale image corresponding to the brightness and position is formed. The brightness reflects the intensity of the sound waves reflected from the tissue interface.

[0003] Currently, there are few fixtures for B-type ultrasound signal acquisition on the market, and most of them have a low degree of integration, making it difficult to adjust the ultrasound probe, which is not conducive to scientific research on human arms. Therefore, technicians in this field are committed to developing an integrated signal acquisition fixture for B-type ultrasound signals to improve the accuracy and efficiency of human arm signal acquisition and make it easier to adjust the probe position.
