X-ray computer tomography device, has image processing condition-selection device selecting image processing condition for executing image processing process for reducing artifacts corresponding to specific values of tomography-value change

摘要

The device (10) has a computer tomography (CT)-value change-specification device (26) for specification of a parameter of change of a CT-value in a body axial direction between tomography images that are obtained by feedback of projection data with respect to pixel areas contained in the images. An image processing condition-selection device (28) selects an image processing condition for executing an image processing process for reducing artifacts corresponding to specific values of the CT-value change. An artifact reduction device executes the process under usage of condition.
