Abstract
A radiation imaging apparatus comprises an image generating unit configured to generate a material characteristic image by using a plurality of radiation images of different radiation energy levels; an evaluation information calculation unit configured to calculate evaluation information which indicates a correlation between a plurality of material characteristic images; and a scattered ray amount estimation unit configured to estimate, based on the evaluation information, an amount of scattered rays included in the plurality of radiation images.
Claims20
A radiation imaging apparatus, comprising:
- a generating unit configured to generate a material characteristic image using a plurality of radiation images of different radiation energy levels captured by a radiation detection apparatus;
- a calculation unit configured to calculate evaluation information indicating a correlation between a plurality of material characteristic images;
- and
- an estimation unit configured to estimate an amount of scattered rays included in the plurality of radiation images based on the evaluation information.
A radiation imaging method, comprising the steps of:
- generating, by an image processing unit, a material characteristic image using a plurality of radiation images using a plurality of radiation images of different radiation energy levels captured by a radiation detection apparatus;
- calculating, by the image processing unit, evaluation information that correlates between a plurality of material characteristic images;
- and
- estimating, by the image processing unit, an amount of scattered rays included in the plurality of radiation images based on the evaluation information.
