摘要： A multislice CT apparatus includes a setting unit, a correcting unit, a filtering unit and a reconstructing unit. The setting unit sets a weighting coefficient in such a way that data on a middle column is weighted high while data on columns on both sides of the middle column is weighted low on a middle channel in a multislice detector, and that a weight given to data on a middle column falls while a weight given to data on both side columns rises as shifting from the middle channel to an end channel. The correcting unit corrects the weighting coefficient in such a way that a weight rises as shifting from a central column to an end column. The filtering unit filters data on the basis of the corrected weighting coefficient in a column direction. The reconstructing unit reconstructs an image on the basis of the filtered data.

摘要： In the X-ray CT system according to an embodiment, a control means displaces and images imaging regions in the subject by controlling a top board driver and an imaging means such that the X-rays are projected onto the subject every time a top board is moved by a predetermined transfer amount. An acquiring means acquires projection data of the respective imaging regions. A reconstruction means, based on the projection data, reconstructs tomographic images for each predetermined size of a reconstruction region. In the scan control mode, the control means outputs the transfer amount corresponding to this mode to the top board driver. In the reconstruction control mode, the control means outputs the size of the reconstruction region corresponding to this mode to the reconstruction means.
