Abstract:
1. An X-ray CT apparatus comprising: an X-ray generation unit configured to irradiate an object with X-rays; an X-ray detection unit including X-ray detection elements corresponding to a plurality of channels, which are arrayed in a predetermined direction to output detection signals upon detecting X-rays transmitted through the object; an image processing unit configured to smooth projection data constituted by numerical values corresponding to detection signals output from the X-ray detection elements corresponding to the plurality of channels so that for all values of a change in the numerical value in a channel direction, the greater the change in the numerical values in the channel direction, the greater a smoothing strength to the projection data; and a reconstruction unit configured to reconstruct an image by using a plurality of projection data smoothed by the image processing unit.
