摘要:
Plural camera heads are each placed in a position capable of detection of radiation emitted from a radiation source. Compton cones obtained from the detection data output from each of the plural camera heads are projected onto three-dimensional space and an image based on the radiation source is reconstructed. In addition, projected images from projecting Compton cones obtained from the detection data output from each camera head onto two-dimensional planes are also employed for determining a three-dimensional space excluding regions where the radiation source is not present. Reconstruction of images based on the radiation source is then performed within the determined three-dimensional space.

摘要:
A radiation source position detection system is provided, wherein three radiation detectors are arranged at different positions. Based on radiations incident to each of the radiation detectors, curved surfaces where a radiation source exists are calculated. By solving equations of each of the curved surfaces simultaneously, the position of the radiation source is detected.
摘要:
Rays incident upon a plurality of detection plates arranged along a normal direction are detected. A distance between the ray and the ray source is estimated based on the number of counted rays detected by each detection plate, and each interval distance of the detection plates. Moreover, the direction of the source of the ray is estimated based on each image obtained from each detection plate.

An image sensor has a CdTe plate, a plurality of hole-type electrodes, and a voltage-applying unit. The hole-type electrodes are arranged at predetermined intervals in the direction of thickness. The voltage-applying unit applies a voltage to the hole-type electrodes. One of the electrodes is not adjacent to any other electrode and is used as an anode. The remaining electrodes are used as cathodes. A sensor-element array is provided on the detecting surface of the image sensor. The array comprises a plurality of sensor elements arranged in the form of a matrix. Each sensor element comprises an anode, a plurality of cathodes, and CdTe lying between the anode and the cathodes.
