Radiological imaging apparatus and radiological imaging method

A radiological imaging apparatus comprising:

• an X-ray source apparatus that radiates X-rays;
• a plurality of first radiation detectors that output an output signal including a first detection signal which is a detection signal of said X-rays that have passed through a test subject and a second detection signal which is a detection signal of γ-rays radiated from said test subject;
• a plurality of second radiation detectors that output an output signal including a first detection signal which is the detection signal of said X-rays and a second detection signal which is the detection signal of said γ-rays;
• a signal processor that calculates an intensity of said first detection signal based on the output signal of said first radiation detector;
• a signal discriminator that separates said second detection signal from the output signal of said second radiation detector;
• and
• a counter that calculates a count rate for the second detection signal separated by said signal discriminator.

A radiological imaging apparatus comprises:

• a test subject holding apparatus provided with a bed which is movable in a longitudinal direction to carry a test subject;
• and
• an image pickup apparatus,
• wherein said image pickup apparatus comprises:
• a radiation detector ring structure that surrounds an area in which said bed is inserted and includes a plurality of radiation detectors;
• an X-ray source that irradiates said test subject with X-rays;
• and
• an X-ray source transfer apparatus that transfers said X-ray source in the circumferential direction of said radiation detector ring structure, and
• said respective radiation detectors output both a first detection signal which is the detection signal of said X-rays that have passed through said test subject and a second detection signal which is the detection signal of γ-rays radiated from said test subject.
