Digitized bone densitometer

Abstract

The invention discloses a digitized bone densitometer. The digitized bone densitometer comprises a box, a CCD (Charge Coupled Device) camera, an image intensifier, a fiber baffle plate, an X-ray assembly, a DR (Digitized Radiography) acquisition workstation and a data acquisition box, wherein a support plate is further arranged inside the box; the X-ray assembly is arranged in the center of the support plate; a 400KHz full-bridge inverter, an active power factor correction circuit, a main control circuit and a filament circuit are further arranged on the support plate; a lead hopper is fixedly arranged on the bottom surface of the support plate; the center of the lead hopper and the center of the ray port of the X-ray assembly are on the same straight line; the fiber baffle plate, the image intensifier and the CCD camera are arranged on a chassis of the box in sequence from top to bottom. The digitized bone densitometer has the advantages of simple structure, working stability, comprehensive functions, accurate detection, small size and easiness in carrying and transportation; the demands on digitized image acquisition, storage, transmission, edition and diagnostic check of a portable computer system can be met.

Description

technical field [0001] The invention relates to a bone mineral detection device, in particular to a digital bone densitometer. Background technique [0002] Existing bone densitometers in the domestic market mainly include ultrasound, ordinary X-rays, and dual-energy X-rays. The ultrasonic bone density instrument has a relatively simple structure, but its function is single, and it cannot make a comprehensive diagnosis of bones, nor can it collect images in real time. Ordinary X-ray bone densitometers mostly use power-frequency X-ray machines, which are bulky and use ordinary image processing systems, resulting in poor image effects. It is easy to misjudge the measurement and evaluation of bone mineral status and the diagnosis of osteoporosis. Although some bone density instruments imported from abroad also realize digital photography, some use dual-energy X-rays, which are large in size and require too long measurement time for each judgment, which is not conducive to the...
