Device for measuring bone density through reference module

Abstract

The invention discloses a device for measuring the bone density through a reference module. The device comprises a digital X-ray imaging device used for collecting a projected image of a measured bone, an image preprocessing device used for preprocessing the image containing the measured bone, an image segmenting processing device used for segmenting the preprocessed image of the measured bone, a bone decay factor calculating device used for calculating bone decay factors of an irradiated part according to the decay characteristic of an X-ray and a bone density equivalent analysis device, wherein the bone density equivalent analysis device enables a m (x,y) value to correspond to an area with the same m (x,y) value in the image formed by a reference module with a known equivalent bone density value, and the equivalent bone density value of the corresponding reference module area is a bone density value of the measured bone part. Compared with a traditional DXA method, the device has the advantages of being high in measurement accuracy, convenient to operate and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for quantitatively measuring bone density using X-ray measuring technology. Background technique [0002] At present, there are a variety of bone density detection methods and products on the market【1】, such as dual-energy X-ray absorptiometry (dual X-ray absorptiometry, DXA), quantitative computed tomography (QCT), quantitative magnetic Resonance method (quantitative magnetic resonance imaging, QMRI) and quantitative ultrasound (quantitative ultrasound, QUS), among which dual-energy X-ray absorptiometry (DXA) is the gold standard method recommended by WHO for clinical diagnosis of osteoporosis, but its There are many weaknesses such as relatively expensive equipment, high maintenance costs, and the need for specially trained professionals to operate. In this case, the combination of artificial intelligence and traditional detection technology has made other new...
