Abstract
A radiographic imaging apparatus comprising: a radiation detector configured to be detachable with respect to a patient platform and detect radiation transmitted through an object in one of a moving image capturing mode and a still image capturing mode; a detection unit configured to detect a shift timing of an image capturing mode; a cooling mechanism configured to cool the radiation detector in one of a first cooling mode and a second cooling mode having a higher cooling capacity than the first cooling mode; and a control unit configured to switch the cooling modes of the cooling mechanism based on detection by the detection unit.
Claims16
A base apparatus comprising:
- an accommodation unit configured to accommodate a radiation detection unit;
- an obtainment unit configured to obtain temperature information of the radiation detection unit;
- a restriction unit configured to restrict removal of the radiation detection unit from said accommodation unit in a case where temperature of the radiation detection unit is greater than or equal to a predetermined threshold, based on the temperature information;
- and
- a release unit configured to release a restriction on removal in a case where temperature of the radiation detection unit is less than the predetermined threshold.
A radiation imaging apparatus comprising:
- a holding unit configured to be detachable with respect to a radiation detection unit and is configured to hold the radiation detection unit;
- an obtainment unit configured to obtain temperature information of the radiation detection unit;
- a restriction unit configured to restrict removal of the radiation detection unit from said holding unit in a case where temperature of the radiation detection unit is greater than or equal to a predetermined threshold, based on the temperature information;
- and
- a release unit configured to release a restriction on removal in a case where temperature of the radiation detection unit is less than the predetermined threshold.
A control method for a base unit which is configured to be detachable with respect to a radiation detection unit and is configured to hold the radiation detection unit, said method comprising:
- obtaining temperature information of the radiation detection unit;
- restricting removal of the radiation detection unit from an accommodation unit in a case where temperature of the radiation detection unit based on the temperature information is greater than or equal to a predetermined threshold;
- and
- releasing a restriction on removal in a case where temperature of the radiation detection unit is less than the predetermined threshold.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a control method for a base unit which is configured to be detachable with respect to a radiation detection unit and is configured to hold the radiation detection unit, the method comprising:
- obtaining temperature information of the radiation detection unit;
- restricting removal of the radiation detection unit from an accommodation unit in a case where temperature of the radiation detection unit based on the temperature information is greater than or equal to a predetermined threshold;
- and
- releasing a restriction on removal in a case where temperature of the radiation detection unit is less than the predetermined threshold.
