RADIATION IMAGING DEVICE AND NUCLEAR MEDICINE DIAGNOSTIC DEVICE USING SAME

摘要

The disclosed radiation imaging device, which is robust (stable) with respect to mis-positioning of a collimator even if detectors and a collimator having conventional manufacturing precision are used, and a nuclear medicine diagnostic device using same are characterized by acquiring incoming position information of radiation at each detector (21) by: the size of a through-hole (27) being set such that one or a plurality of pixels are arrayed in a plan view from a perpendicular direction; septa (28) being disposed offset from the boundary line between detector pairs in a plan view from the perpendicular direction; septa (28) being further disposed in a manner so as to be perpendicular to the boundary line between detector pairs in a plan view from the perpendicular direction; the top of the through-hole (27) in a plan view from the perpendicular direction being disposed offset from the boundary line of detector pairs; and the top of the detectors (21) in a plan view from the perpendicular direction being disposed in a manner so as to be visible through the through-hole (27).
