Abstract:
An x-ray CT apparatus, comprising:a gantry including: an x-ray source which generates an x-ray cone beam, a radiation detector having a plurality of element blocks, each element block having a plurality of detection elements which are arranged in a matrix form and which detect x-rays transmitted-through an object, and a rotating device which allows the x-ray source and the radiation detector to rotate continuously to permit said gantry to continuously acquire projection data on the object; and a reconstructing unit which reconstructs volume data acquired at an arbitrary timing, on the basis of the projection data, wherein each of said plurality of element blocks is formed on a corresponding one of a plurality of block substrates, said plurality of block substrates are formed in a direction parallel to a rotational axis of the radiation detector to obtain each of a plurality of modules, and said plurality of modules are arranged in a direction perpendicular to the rotational axis of the radiation detector on a base of the radiation detector.
