PROBLEM TO BE SOLVED: To provide an X-ray CT apparatus capable of equalizing a level of noise depending on a length of a wiring length from an X-ray detector to a DAS (Data Acquisition System) when creating a wide-coverage detector structure having a simultaneous collection system.SOLUTION: An X-ray CT apparatus includes: an X-ray source emitting X-rays; an X-ray detector detecting X-rays transmitted through a subject and converting the detected X-rays into electric signals; a detection module 58 mounted with conversion elements 60, 61, 62, 63 converting the converted electric signals into digital signals from analog signals; and an image processing part reconstructing a tomographic image of the subject from the digital signals converted by the conversion elements 60, 61, 62, 63. The detection module 58 has first and second boards 50, 51, 53, 54 partially formed with cutouts, and the conversion elements 61, 63 mounted on the first boards 50, 53 are provided oppositely to the cutouts of the second boards 51, 54. |
