Abstract

The invention discloses an opto-acoustic and ultrasonic dual-mode osteoporosis detection method and a detection device. The detection device is composed of two parts, namely a host machine and a probe, wherein the host machine comprises a laser device, a laser modulator, a collimating and coupling unit, a display module, an opto-acoustic mode changeover switch, an ultrasonic signal driver and a processor; the probe is composed of an acoustic emission focusing probe, a pre-amplifier, an ultrasonic transducer array and a transparent colloid; and the transparent colloid is attached on human skin. The device disclosed by the invention integrates opto-acoustic and ultrasonic advantages and solves the problem that an existing bone quality assessment DXA (dual X ray absorptiometry) cannot provide bone collagen information, while bone quality is determined by bone density and bone collagen, in which the bone density determines bone strength and the content of the bone collagen determines bone toughness; and a bone quality assessment capacity can be significantly improved by virtue of an opto-acoustic / ultrasonic imaging technology. The detection method and the detection device disclosed by the invention have the obvious advantages of being noninvasive, free from radiation, low in detection cost, accurate in assessment 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 ...
