Abstract
In a case of deriving a subtraction image in which a specific tissue in a subject is extracted, the subtraction image being derived by performing weighting subtraction on a plurality of radiation images acquired by imaging the subject with radiation having different energy distributions and being subjected to predetermined image processing, a reaching dose which is a radiation dose that directly reaches a radiation detector that acquires the radiation image is acquired, and the subtraction image is derived by performing the image processing based on the reaching dose.
Claims10
A radiation image processing device that derives a subtraction image in which a specific tissue in a subject is extracted, the subtraction image being derived by performing weighting subtraction on a plurality of radiation images acquired by imaging the subject with radiation having different energy distributions and being subjected to predetermined image processing, the radiation image processing device comprising:
- at least one processor,
- wherein the processor
- acquires a reaching dose which is a radiation dose that directly reaches a radiation detector that acquires the radiation image, and
- derives the subtraction image by performing the image processing based on the reaching dose.
A radiation image processing method of deriving a subtraction image in which a specific tissue in a subject is extracted, the subtraction image being derived by performing weighting subtraction on a plurality of radiation images acquired by imaging the subject with radiation having different energy distributions and being subjected to predetermined image processing, the radiation image processing method comprising:
- acquiring a reaching dose which is a radiation dose that directly reaches a radiation detector that acquires the radiation image;
- and
- deriving the subtraction image by performing the image processing based on the reaching dose.
A non-transitory computer-readable storage medium that stores a radiation image processing program causing a computer to execute a procedure of deriving a subtraction image in which a specific tissue in a subject is extracted, the subtraction image being derived by performing weighting subtraction on a plurality of radiation images acquired by imaging the subject with radiation having different energy distributions and being subjected to predetermined image processing, the radiation image processing program causing the computer to execute:
- a procedure of acquiring a reaching dose which is a radiation dose that directly reaches a radiation detector that acquires the radiation image;
- and
- a procedure of deriving the subtraction image by performing the image processing based on the reaching dose.
