Radiological imaging apparatus, radiological imaging method, and program

A radiological imaging method, comprising:

• detecting signals from a plurality of signal generating sections disposed in a manner such that each signal generating section is at a different location on a radiation detection section that detects radiation that passes through a subject from a radiation source that generates radiation that irradiates the subject;
• comparing the detected signals from the plurality of signal generating sections;
• making a judgment as to whether a positional relationship between the radiation detection section and the radiation source is a predetermined positional relationship based on a comparison result;
• controlling a position of at least one of the radiation source and the radiation detection section to maintain the positional relationship between the radiation source and the radiation detection section as the predetermined positional relationship based on a judgment result;
• holding the radiation source and the radiation detection section in the set position and fixing the positional relationship between the radiation detection section and the radiation source after the positional relationship is caused to be the predetermined positional relationship;
• providing notification in a case where a judgment is made that the positional relationship is not the predetermined positional relationship while the radiation source and the radiation detection section are being held in the set position;
• making a judgment as to whether the radiation source and the radiation detection section can be held in the predetermined positional relationship based on a comparison result and a range in which the radiation source and the radiation detection section can move;
• and
• warning a user in a case where a judgment is made that the radiation source and the radiation detection section cannot be held in the predetermined positional relationship.

A computer-readable medium which stores a program used by a radiological imaging apparatus that causes the radiological imaging apparatus to function as:

• a radiation source that generates radiation irradiating a subject;
• a radiation detection section that detects radiation from the radiation source that passes through the subject;
• a signal detection section that detects signals from a plurality of signal generating sections disposed on the radiation detection section in a manner such that each signal generating section is in a different location;
• a signal comparison section that compares the signals from the plurality of signal generating sections detected by the signal detection section;
• a positional relationship judgment section that makes a judgment as to whether a positional relationship between the radiation detection section and the radiation source is a predetermined positional relationship based on a comparison result from the signal comparison section;
• a position control section that controls a position of at least one of the radiation source and the radiation detection section to maintain the positional relationship between the radiation source and the radiation detection section as the predetermined positional relationship based on a judgment result from the positional relationship judgment section;
• a position control holding section that holds the radiation source and the radiation detection section in the position set by the position control section and fixes the positional relationship between the radiation detection section and the radiation source after the position control section causes the positional relationship to be the predetermined positional relationship;
• a notification section that provides notification in a case where the positional relationship judgment section makes a judgment that the positional relationship is not the predetermined positional relationship while the position control holding section is holding the radiation source and the radiation detection section in the position set by the position control section;
• a position judgment section that makes a judgment as to whether the radiation source and the radiation detection section can be held in the predetermined positional relationship based on a comparison result from the signal comparison section and a range in which the radiation source and the radiation detection section can move;
• and
• a warning section that warns a user in a case where the position judgment section makes a judgment that the radiation source and the radiation detection section cannot be held in the predetermined positional relationship.
