Abstract:
A method of acquiring transmitted-radiation image data on a subject, by emitting cone radiation from a radiation source toward said subject and by detecting said cone radiation transmitted through said subject with a solid radiation detector, while said radiation source and said solid radiation detector disposed with said subject therebetween are being rotated relatively with respect to said subject;said method comprising the steps of employing a plurality of line sensors as said solid radiation detector; dividing an entire detection area for each direction of projection into a plurality of division areas; disposing each of said line sensors in each of said division area so that each of said line sensors is movable within said division area; and obtaining an entire detection area quantity of transmitted-radiation image data by detecting said cone radiation transmitted through said subject with each of said line sensors, while each of said line sensors is being moved within each of said division areas.
