A Small Ultrasonic Measuring System for Thin Material Characterization

Abstract

The invention discloses a miniature ultrasonic measurement system for lamina material characterization. The miniature ultrasonic measurement system comprises a probe device in a tubular structure, a miniature water pump, a medical sink and a master control system. The miniature water pump is connected with the medical sink through a hose; a pump outlet of the miniature water pump is connected with a couplant pipeline port in the probe device in the tubular structure through a hose; the probe device in the tubular structure comprises a main pipe body, a detachable sprayer, an electrical adaption port and the couplant pipeline port; the master control system comprises an ultrasonic transmitting / receiving device, a high-frequency signal collector, a single-shaft movement controller, an ultrasonic distance measuring module, a motor driving module, an embedded controller and a display screen. The miniature ultrasonic measurement system has the advantages that ultrasonic detection of materials in a narrow cavity is realized by the aid of the thin tubular structure; an automatic focusing function of a point focusing ultrasonic probe is realized by the aid of a single-shaft precision movement device; spatial positions of signal acquisition are precisely recorded by an ultrasonic high-frequency distance measuring probe, and acquisition of data needed for lamina material characterization is facilitated.

Description

technical field [0001] The invention relates to the field of ultrasonic measurement, in particular to a small-sized ultrasonic measurement system for characterization of thin-layer materials. Background technique [0002] Osteoarthritis is a common joint disease that seriously affects the quality of life of patients. Modern medicine has confirmed that one of the most important changes in osteoarthritis is cartilage degeneration. The main method currently used to diagnose cartilage lesions is to use X-ray imaging, but this method can only be used for the diagnosis of advanced lesions. The standardization of the diagnosis of nasal inflammation, oral inflammation and other diseases requires a more mathematical description of tissue lesions, which requires quantitative analysis of the degree and type of swelling of the inflammatory site in the cavity. With the advancement of ultrasound medicine, especially the advancement of ultrasound tissue characterization technology in rec...
