Abstract: A beam irradiation device includes: a laser light source for emitting laser light; an actuator which scans a targeted area with the laser light; a servo optical system which changes a propagating direction of servo light in response to driving of the actuator; a photodetector which receives the servo light to output a signal depending on a light receiving position of the servo light; an actuator controlling section which controls the actuator based on the signal to be outputted from the photodetector; and a laser controlling section which controls the laser light source based on the signal to be outputted from the photodetector. The laser controlling section controls the laser light source to emit the laser light in a pulse manner at a timing when the light receiving position of the servo light coincides with a predetermined targeted position.

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.

Abstract: A beam irradiation device includes a photodetector which receives servo light; a signal processing section which generates a position detection signal based on a detection signal from the photodetector; and a control section which controls the laser light source and the actuator for beam scanning based on the position detection signal. The signal processing section performs a sampling operation with respect to the detection signal from the photodetector at two consecutive sampling timings. The signal processing section includes an A/D converting section which converts a difference between two sampling values obtained by the sampling operation into a digital signal, and a computing section which computes the position detection signal based on the digital signal from the A/D converting section.
