Abstract
An X-ray CT apparatus including an X-ray tube, a detector array including a plurality of detector rows along the axis of rotation, and a reconstructing section for calculating and reconstructing tomographic image data of a subject based on the acquired projection data. The CT apparatus also includes a collimator for adjusting the emission extent of the X-rays from the X-ray tube in response to a control command, and a control section for calculating detector rows required for acquiring the projection data for use in reconstruction of a certain portion of the tomographic image data based on parameters relating to reconstruction of the tomographic image data by the reconstructing section, and outputting the control command to the collimator for emitting the X-rays to impinge upon the calculated detector rows.
