<p><P>PROBLEM TO BE SOLVED: To provide a radiographic imaging apparatus capable of quickly identifying a position, intensity, and type of a radiation source, and instantly determining the soundness of the apparatus. <P>SOLUTION: A radiographic imaging apparatus includes; a gamma camera having a sensor for measuring radiation and a pinhole collimator located in front of the sensor for restricting the incident direction of the radiation; an optical camera for capturing optical images; and a range finder. The apparatus is also equipped with display control means for displaying a radiographic image 60, which is a radiographic image produced from the measurement data of the gamma camera superimposed on an optical image captured by the optical camera, and an energy spectrum 70 from radiation data measured by the sensor on an image display device, which enables quickly identifying a position, intensity, and type of a radiation source and determining the soundness of the sensor from the energy spectrum 70. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
