装置。 A CT head comprising a head-mounted part to be attached to the head of a subject, and a head-mounted part fixing device which is fixed to a headrest of a CT bed and which fixes the head-mounted part to the headrest. The head-mounted part includes a reference axis means for constructing a stereoscopic image, which serves as a reference for constructing a stereoscopic image by superimposing a plurality of planar tomographic images of a living body, and a reference axis means for constructing a stereoscopic image, and Comparatively calculate the bone mineral content of the head and neck by simultaneously performing CT imaging of a bone mineral equivalent material having a known bone mineral content during CT imaging of the head and neck. A head fixation device for CT, characterized in that it has a bone mineral quantitative analysis means.
