Abstract

The purpose of the invention is to display bone mineral density and the measured values on which same is based in a form that is suitable for bone diagnoses. The bone mineral density-measuring device acquires bone mineral distribution data wherein the three-dimensional distribution of bone minerals is projected onto a plane based on X-rays passing through the subject. The bone mineral density-measuring device determines bone mineral content, bone area and bone mineral density based on the bone mineral distribution data and displays the determined bone mineral content, bone area and bone mineral density on a display. Bones that are subjects for diagnosis are, for example, the second, third and fourth lumbar vertebrae. On the display, an image showing the bone mineral densities (D2 - D4), bone areas (S2 - S4) and the bone mineral contents (C2 - C4) of the second - fourth lumbar vertebrae on the vertical axis and the examination times on the horizontal axis is displayed.

Description

technical field [0001] The present invention relates to a bone density measuring device, in particular to a device for displaying bone density obtained through multiple examinations on the same subject. Background technique [0002] Bone density exists as an evaluation value for diagnosing osteoporosis and the like, and bone density measurement devices that measure bone density by X-rays are widely used. The bone density measurement device detects the X-rays emitted by the X-ray generator and transmitted through the subject through the X-ray detector, and measures the bone mineral distribution of the subject according to the detection result. The bone density measuring device calculates the amount of bone salt and the bone area based on the measured bone salt distribution. Then, the bone density is obtained by dividing the amount of bone salt by the bone area, and the bone density is displayed on the monitor. Here, the amount of bone mineral and the bone area that are the ...
