Abstract
A composition information obtaining unit calculates a mammary gland/fat ratio and a first information obtaining unit obtains imaged contrast information representing a contrast of the radiation image. A second information obtaining unit sets target application condition of X-ray, and obtains target contrast information representing an intended contrast for the radiation image based on the intended application condition. A contrast correction amount determination unit determines a contrast correction amount based on the imaged contrast information and the target contrast information. An image processing unit performs image processing, including gradation processing based on the determined contrast correction amount, on the radiation image, and obtains a processed radiation image.
Claims14
A radiation image processing apparatus, comprising:
- a radiation image obtaining unit that obtains a radiation image of a subject;
- a first information obtaining unit that obtains imaged contrast information representing a contrast of the radiation image;
- a second information obtaining unit that sets an intended application condition of the radiation, and obtains target contrast information representing an intended contrast for the radiation image based on the intended application condition;
- a contrast correction amount determination unit that determines a contrast correction amount for the radiation image based on the imaged contrast information and the target contrast information;
- and
- an image processing unit that performs image processing, including gradation processing based on the determined contrast correction amount, on the radiation image and obtains a processed radiation image.
A radiation image processing method, comprising the steps of:
- obtaining a radiation image of a subject;
- obtaining imaged contrast information representing a contrast of the radiation image;
- setting an intended application condition of the radiation, and obtaining target contrast information representing an intended contrast for the radiation image based on the intended application condition;
- determining a contrast correction amount for the radiation image based on the imaged contrast information and the target contrast information;
- performing image processing, including gradation processing based on the determined contrast correction amount, on the radiation image;
- and
- obtaining a processed radiation image.
