Title:
マルチスライスＣＴ装置及びデータ前処理方法
Document Type and Number:
Japanese Patent JP5872212
Kind Code:
B2
Abstract:
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.
