Description
Technical field
The present invention relates to the medical ultrasonics application, especially the method for medical measurement human body calcaneus bone intensity index is specially the ultrasonic bone strength index of a kind of absolutely dry solid-state manifold type calcaneus detection method.
Background technology
Osteoporosis is one of modal chronic disease of middle-aged and elderly people, and it has become threat human health and the key factor of quality of life.Osteoporosis is a kind of systemic osteopathia, it is characterized in that the decline of bone mineral density (bone density) and the fine structure of bone destroy, the fragility that shows as bone increases, thereby the danger of fracture greatly increases, even also fracture easily under slight wound or the atraumatic situation.According to the data of World Health Organization (WHO), the seriousness of osteoporosis is only second to the cardiovascular diseases, threatens greater than diseases such as breast carcinoma, carcinoma of prostate.In a single day osteoporosis is made a definite diagnosis, and under existing medical technique level, also do not have effective method for treatment, thereby early prevention is extremely important.By strengthening life style intervention and corresponding Drug therapy, improve the fine structure of bone mineral density and bone, can reduce risk of bone fracture.World Health Organization (WHO) announces that disease knochenbruch matter osteoporosis standard is:
1. sclerotin is normal: bone density is not less than normal 1 standard deviation of meansigma methods (T value 〉=-1) with the young adult's bone density of sex peak value.
2. osteopenia (bone-loss): bone density is lower than normally the meansigma methods (2.5＜T value＜-1) between 1～2.5 standard deviation with the young adult's bone density of sex peak value.
3. osteoporosis: bone density is lower than normally 2.5 standard deviations of meansigma methods or following (T value≤-2.5) with the young adult's bone density of sex peak value
Therefore, bone density measurement seems particularly important.Just set about studying the BMD method for quantitative measuring from the thirties in 20th century.Be mainly x-ray method and X ray optical densitometric method etc. in the past in the sixties, all relatively poor because of its sensitivity and accuracy, seldom use.Development along with electronics, sensing and the information processing technology, successively there is the method for multiple detection BMD to occur, mainly comprise single photon absorptiometry (SPA), two-photon absorption method (DPA), dual intensity X line absorption mensuration (DEXA), quantitative CT (QCT), the said method accuracy of detection is higher, but equipment price costliness, measuring process are loaded down with trivial details, are suitable as clinical definite and use.
In recent years, it is swift and violent that quantitative ultrasound (QUS) is measured the development of bone density measuring technology.Quantitative ultrasound mainly utilizes ultrasound wave to penetrate the bone density that positions such as calcaneus are measured in decay, its major parameter is broadband ultrasonic attenuation BUA, ultrasonic propagation velocity SOS and the bone strength index STI that obtained by the two linear combination, wherein bone strength index STI can not only reflect bone mass, can also reflect bone structure.Simultaneously, advantages such as ultrasonic measurement is cheap, easy and simple to handle, radiationless risk become the desirable inspection method that early diagnosis and prediction are fractured.
Application number is that 200620072519.1 Chinese patent discloses a kind of method and apparatus that utilizes ultrasonic attenuation to detect calcaneus density, but the not concrete mode that proposes probe clip immediately following bone of this patent, there is certain thickness soft tissue structure the calcaneus outside, can cause Soft Tissue Deformation at probe clip immediately following in the bone process, therefore in the time of can't guaranteeing that each probe clamps, the Soft Tissue Deformation degree is consistent, can't guarantee that promptly the position of each actual measurement is consistent, thereby influence the ultrasonic measurement precision; It is a kind of by measuring test calcaneus position temperature that application number is that 200610059647.7 Chinese patent discloses, with this temperature serves as according to the measuring method that compensates ultrasonic propagation velocity, but this method is just measured tester's calcaneus position temperature, because measuring the calcaneus position exposes to the open air with extraneous, its variations in temperature is because of differing greatly that the difference of ambient temperature causes, therefore compensation exists than mistake, and what may cause measuring is inaccurate; Application number is that 200820118612.0 Chinese patent discloses a kind of ultrasonic bone density detector, mentions in this patent and uses a kind of vesicle to be loaded on the probe, vesicle is not carried out concrete elaboration.
