Ultrasonic bone strength evaluating and diagnosing instrument

Abstract

The invention discloses an ultrasonic bone strength evaluating and diagnosing instrument. The ultrasonic bone strength evaluating and diagnosing instrument comprises a transmitting module, a receivingmodule, a detecting region, a processing module, a calculation module and an output module, wherein transmitted signals transmitted by the transmitting module penetrate through the detecting region and are received by the receiving module; the processing module calculates phase velocity c according to sound velocity of the transmitted signals and the received signals; the calculation module calculates bone strength evaluating T indexes through the phase velocity c; and the output module outputs T index results. A quantitative ultrasonic measuring result is in direct contact with the inherentessence and the final result of osteoporosis, troublesomeness which is difficult to measure of BUA is reduced, the manufacturing cost and the using difficulty can be reduced remarkably, promotion andapplication are facilitated, and osteoporosis can be evaluated and diagnosed rapidly and scientifically.

Description

technical field [0001] The invention relates to the field of digital medical equipment, in particular to an acoustic bone strength evaluation diagnostic instrument. Background technique [0002] According to the definition proposed by some groups in 1993, osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural degradation of bone tissue, with secondary aggravation of bone fragility and susceptibility to fracture. From the perspective of biomechanics, fracture refers to the phenomenon that the external force on the bone exceeds its mechanical strength, resulting in partial or overall fracture. Osteoporosis refers to the phenomenon that the elastic modulus and mechanical strength of the bone decrease due to changes in the chemical composition and structural degradation of the bone. However, because the existing definition of osteoporosis is partial to the description of the phenomenon, there is no connection and point out the essential...

[0017] Due to the occurrence of these deviations, after the prosperity in the late 1990s, there have been few significant and practical achievements in the field of QUS, and some work even duplicated and developed others' mistakes, resulting in the lack of scientific guidance in the industry and clinical medicine. into serious confusion and confusion
