A photoacoustic and ultrasonic dual-mode osteoporosis detection method and device

Abstract

The invention discloses a photoacoustic and ultrasonic dual-mode osteoporosis detection method and device, which consists of two parts, namely a host and a probe, wherein the host includes a laser, a laser modulator, a collimation coupling unit, a display module, an optical An acoustic mode switching switch, an ultrasonic signal driver and a processor; the probe is composed of an acoustic emission focusing probe, a preamplifier, an array of ultrasonic transducers, and a transparent colloid, and the transparent colloid is pasted on human skin. The reported device combines the advantages of photoacoustics and ultrasound, and solves the problem that the existing bone quality evaluation DXA cannot provide collagen information, and bone quality depends on bone density and bone collagen, in which bone density determines bone strength, and bone collagen content determines bone quality. Toughness, photoacoustic / ultrasound imaging will significantly improve the ability to evaluate bone quality. The invention has the obvious advantages of no trauma, no radiation, low detection cost, accurate evaluation and the like.

Description

technical field [0001] The invention relates to the technical field of bone density detection, in particular to a photoacoustic and ultrasonic dual-mode osteoporosis detection method and device. Background technique [0002] According to the 2009 China White Paper on Osteoporosis: my country has become the country with the most patients with osteoporosis or low bone density in the world, with about 214 million patients. With the increase of average life expectancy and the emergence of aging population, It is estimated that by 2020, the number of patients with osteoporosis or low bone density will reach 286 million, and about 20% of patients with osteoporosis or low bone density will have osteoporotic fractures. Osteoporosis is also a chronic disease that consumes a large amount of national medical resources and economic resources. Calculated according to the yearly increase in the incidence rate, the cost for the treatment of hip fractures caused by osteoporosis in 2006 will ...
