Abstract: A distortion compensation unit compensates distortion in the amplifier by using a distortion compensation coefficient that is in accordance with a power value of a signal before amplification in the amplifier. An updating unit updates, on the basis of the signal before amplification in the amplifier and a signal after amplification in the amplifier, the distortion compensation coefficient. An extracting unit extracts, at a predetermined number of measurement periods, when the power value of the signal before amplification in the amplifier is equal to or greater than a threshold, the distortion compensation coefficient that is in accordance with the power value. A first calculating unit calculates, by using an average value of the extracted distortion compensation coefficients, an amount of variation in the distortion compensation coefficient. A determination unit determines, on the basis of the calculated amount of variation in the distortion compensation coefficient, whether the amplifier is degraded.

Abstract: 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.
