Patent ID: 7986767

Claim:
A radiographic image detection apparatus comprising: a radiation source that outputs radiation to a subject; a radiographic image detector that detects, as a radiographic image, the radiation that has been output from the radiation source to the subject and that has passed through the subject; a detector movement means that moves the position of the radiographic image detector; a radiation-source movement means that moves the position of the radiation source; a standard position database that stores, in advance, a standard position of the radiographic image detector and a standard position of the radiation source for obtaining the radiographic image by changing the position of the radiographic image detector and the position of the radiation source; an actual-past-radiography position database that stores, as actual-past-radiography positions, the position of the radiographic image detector and the position of the radiation source when radiography was actually performed, associating the position of the radiographic image detector and the position of the radiation source with information about the subject; and an aid-information output means that outputs, as aid information, position adjustment amounts for adjusting the positions of the radiation source and the radiographic image detector from the standard positions stored in the standard position database when the radiation source and the radiographic image detector are positioned to perform radiography, wherein the aid information is output based on the actual-past-radiography positions that are stored in the actual-past-radiography position database and that are associated with the information about the subject.
