BONE DENSITY AND BODY COMPOSITION MEASURING APPARATUS OF DEXA TYPE USING BODY PRE-DETECTION SYSTEM

摘要

The present invention provides a method performed by a device for measuring bone mineral density and body composition based on the DEXA method. The method includes the steps of capturing a body shape and an attitude of a subject in a two-dimensional or three-dimensional image; Extracting coordinate information on an outline or an outline of the body shape and posture of the subject from the photographed image; Comparing the body information of the subject to be measured with the previously stored body information including the thickness of the soft tissue and skeletal positions of the plurality of body shapes and extracting the body information corresponding to the body shape and the degree of matching of the subject ; Calculating a dose of X-rays to be emitted to a measurement position based on the extracted coordinate information and the extracted body information; And the X-ray generating unit is moved to adjust the dose of the X-ray generating unit according to the calculated result of the X-ray dose, the X-ray is not emitted from the outside of the subject, And increasing the amount of X-ray emission at the other positions.
