Abstract
A dose measured from region information, X-ray information, and a captured image in a previous imaging operation and a dose of radiation obtained from a DAP meter are saved as pieces of information. A dose used in a first imaging operation is based on the saved pieces of information, and a dose to be used in a second imaging operation is estimated from region information or X-ray information in the second imaging operation. If there is a significant difference between the dose in the first imaging operation and the estimated dose for the second imaging operation, a warning is issued. If an image of a region is captured for testing purposes, a warning is not issued.
Claims18
An imaging management apparatus that obtains an X-ray image obtained as a result of X-ray imaging performed by an X-ray reception unit and an X-ray generation unit and that manages information regarding the X-ray imaging, the imaging management apparatus comprising:
- a first obtaining unit configured to obtain information regarding a dose in a first X-ray imaging operation performed by the X-ray generation unit and the X-ray reception unit;
- a second obtaining unit configured to obtain, after X-ray radiation corresponding to the first X-ray imaging operation but before X-ray radiation corresponding to a second X-ray imaging operation, which is managed by the imaging management apparatus and performed after the first X-ray imaging operation, information regarding a dose in the second X-ray imaging operation;
- and
- an output control unit configured to cause, after the X-ray radiation corresponding to the first X-ray imaging operation but before the X-ray radiation corresponding to the second X-ray imaging operation, an output unit to issue a warning on the basis of a difference between a value based on the information regarding the dose in the first X-ray imaging operation and a value based on the information regarding the dose in the second X-ray imaging operation.
An X-ray imaging system comprising:
- a reception unit configured to receive imaging information regarding a plurality of X-ray imaging operations performed by an X-ray generation unit and an X-ray reception unit;
- a first obtaining unit configured to obtain information regarding a dose in a first X-ray imaging operation among the plurality of X-ray imaging operations;
- a second obtaining unit configured to obtain, after X-ray radiation corresponding to the first X-ray imaging operation but before X-ray radiation corresponding to a second X-ray imaging operation, which is managed by an imaging management apparatus and performed after the first X-ray imaging operation, information regarding a dose in the second X-ray imaging operation;
- and
- an output control unit configured to cause, after the X-ray radiation corresponding to the first X-ray imaging operation but before the X-ray radiation corresponding to the second X-ray imaging operation, an output unit to issue a warning on the basis of a difference between a value based on the information regarding the dose in the first X-ray imaging operation and a value based on the information regarding the dose in the second X-ray imaging operation.
A method for processing information used for managing information regarding X-ray imaging performed by an X-ray reception unit and an X-ray generation unit, the method comprising the steps of:
- obtaining information regarding a dose in a first X-ray imaging operation performed by the X-ray generation unit and the X-ray reception unit;
- obtaining, after X-ray radiation corresponding to the first X-ray imaging operation but before X-ray radiation corresponding to a second X-ray imaging operation, which is managed by an imaging management apparatus and performed after the first X-ray imaging operation, information regarding a dose in the second X-ray imaging operation;
- and
- causing, after the X-ray radiation corresponding to the first X-ray imaging operation but before the X-ray radiation corresponding to the second X-ray imaging operation, an output unit to issue a warning on the basis of a difference between a value based on the information regarding the dose in the first X-ray imaging operation and a value based on the information regarding the dose in the second X-ray imaging operation.
