Abstract
A filter processing means removes periodic patterns caused by a scattered radiation removing means from radiation images, which are obtained by detecting radiation that has passed through the scattered radiation removing means with a radiation detector. The filter processing means removes only the spatial frequency components of the periodic pattern from the radiation images.
Claims5
A radiation image processing apparatus equipped with a scattered radiation removing means for removing scattered components of radiation, that removes periodic patterns caused by the scattered radiation removing means from radiation images, which are obtained by detecting radiation, which has passed through a subject, with a radiation detector via the scattered radiation removing means, comprising:
- data holding means, for holding spatial frequency components of the periodic patterns within the radiation images;
- and
- filter processing means, for removing only the spatial frequency components of the periodic pattern, which are held in the data holding means, from the radiation images.
