TRABECULAR BONE ANALYZER

摘要

Disclosed herein is a trabecular bone analyzer that can quantitatively determine the state of trabecular bone accurately. The trabecular bone analyzer of may perform trabecular bone analysis on a tomographic image D. In the tomographic image D, trabeculae forming a network may appear without overlapping. Therefore, such trabecular bone analysis may more accurately quantify trabecular bone.

主权项

1. A trabecular bone analyzer comprising:
a radiation source configured to emit radiation; a flat panel detector to detect radiation that has passed through a subject; a radiation source moving unit configured to move the radiation source in one direction; a radiation source movement control unit configured to control the radiation source moving unit; an image generating unit configured to generate an image based on an output from the flat panel detector; an image reconstructing unit configured to generate a tomographic image based on images continuously taken by moving the radiation source with respect to the subject; trabecular bone analyzing unit configured to calculate, based on the tomographic image, data for quantitatively determining a state of trabecular bone; and means for estimating a ratio of trabecular bone that occupies a predetermined space obtained from the data calculated by the trabecular bone analyzing unit.
