Classification: CPC A  G | IPC A  G

Claim 5:
6. A radiographic image processing method comprising:
acquiring a first radiographic image and a second radiographic image that include a same subject and have different S/N ratios;
deriving a body thickness map indicating a body thickness or a bone mineral content map of the subject on the basis of at least one of the first radiographic image or the second radiographic image;
deriving a processing content of a first graininess suppression process on the first radiographic image having a higher S/N ratio of the first radiographic image and the second radiographic image on the basis of a difference between a body thickness of a pixel of interest and a body thickness of a pixel around the pixel of interest in the first radiographic image based on the body thickness map, or on the basis of a difference between a bone mineral content of the pixel of interest and a bone mineral content of the pixel around the pixel of interest in the first radiographic image based on the bone mineral content map;
deriving a processing content of a second graininess suppression process on the second radiographic image on the basis of the processing content of the first graininess suppression process; and
performing a graininess suppression process on the second radiographic image on the basis of the processing content of the second graininess suppression process.
