Abstract
Abstract A micro gamma camera having several gamma radiation detection devices adjacent to each other. The detection devices are laid out above an information processing device that processes information output by the detection devices. Each of the detection devices includes: a plurality of detectors positioned adjacent to each other to form a detection plane; a first substrate including a detection plane polarizer and a first signal processor for processing the signal detected by the detection plane; a second substrate placed between the detection plane and the first substrate; a ground plane placed between the first and second substrates; and a third substrate including second and third signal processors.
