X-ray ct apparatus

Abstract

Provided is an X-ray CT apparatus capable of reducing manufacturing man-hours of an X-ray detector that is multi-sliced in a body axis direction of a subject. An X-ray CT apparatus includes: an X-ray source that irradiates a subject with X-rays; an X-ray detector that detects the X-rays transmitted through the subject; a signal processing unit that obtains a plurality of projection data based on an electric signal output from the X-ray detector; and an image generation unit that generates a tomographic image by using the projection data, in which the X-ray detector includes a plurality of detector modules that are arranged in a channel direction, the detector module includes sub-detector modules that are arranged in a body axis direction of the subject, and the sub-detector module is configured such that a plurality of tiling modules that convert the X-rays into an electric signal are associated with one collimator that removes scattered rays.
