Abstract:
An X-ray CT apparatus in which an X-ray tube and an X-ray detector are opposed to each other interposing a subject, in which detector a multiplicity of X-ray detector elements are linearly arranged in the channel arrangement direction to form a plurality of rows in the subject body axis direction, for reconstructing a CT tomographic image of the subject based on detected signals from the X-ray detector, comprising:a signal duplicating device for duplicating channel detected signals of the X-ray detector and distributing the duplicated signals to a plurality of groups; a signal combining device that can combine said distributed duplicated signals in each group in an arbitrary pattern across the detector rows for each channel; and a data collecting device for converting said channel combined signals for each group into projection data for each channel and collecting the projection data along the channel arrangement direction.
