Problems solved by technology

[0004] Existing DEXA detection devices irradiate a certain amount of X-rays regardless of the size of the subject or the thickness of the test site, so that the subject is excessively exposed to X-rays, which eventually leads to a saturation failure of the detector
However, if the radiation dose is reduced to prevent this problem, the SNR (Signal to Noise Ratio) will eventually decrease due to insufficient photons reaching the detector

Abstract

Disclosed are techniques related to measuring dual energy x-ray absorptiometry (DEXA)-type bone density and body composition, capable of: photographing the body of a person to be measured through a photographing means, so as to acquire a two-dimensional or three-dimensional image for the body type and the positioning of the person to be measured; and adjusting an X-ray dose according to a moving trajectory of an X-ray generator in response to the body type and the positioning, of the person to be measured, identified from the two-dimensional or three-dimensional image.

Description

technical field [0001] The invention relates to a detection system using X-rays and a detection method thereof. Background technique [0002] The content described below is only for providing background information related to this embodiment, and does not constitute prior art. [0003] An X-ray bone density measuring device that transmits X-rays to a subject and calculates bone density is widely used by many medical institutions as a device for diagnosing and preventing bone diseases. As is well known, bones are composed of minerals such as calcium (osteitis) that attenuate X-rays, so the bone density per unit area can be determined by calculating the amount of attenuation when X-rays are transmitted. Since the bone is covered by soft tissues such as muscle and fat, there is attenuation of X-rays in this part. In order to eliminate the influence of the soft tissue, existing bone density detection devices generally use X-rays with two energies. It solves simultaneous equat...
