Abstract: The present invention is directed to a structure for mounting a photomultiplier tube to a scintillator comprising fixing means for fixing a PMT for detecting visible ray to a scintillator panel (30) generating the visible ray by radiation collision, wherein said fixing means are formed as a clamp (20) with a holder (25) on a front part (21), which makes the PMT (10) contact with the scintillator panel, and wherein securing means for securing said clamp (20) to the upper and lower surfaces of the scintillator panel (30) is included. Accordingly, it is possible to conveniently mount the PMT without any damage to the scintillator panel, and thus, the optical loss due to the cracks within the scintillator panel occurring when mounting the PMT of the prior art and the screws inserted in the scintillator panel are eliminated, so that the measurement of radiation can be more accurately performed.

Abstract: The present invention relates to a scintillation detector, which is largely divided into a scintillator and a photomultiplier, as a constituent element of a medical diagnostic imaging equipment, a scintillator, and a medical diagnostic imaging equipment using the same, and more specifically, to a plastic scintillator, and a scintillation detector and a medical diagnostic imaging equipment using the same wherein a plastic scintillator is provided as a scintillator constituting a scintillation detector of a medical diagnostic imaging equipment instead of a known crystal scintillator, thereby allowing easy processing of a scintillator, improving detection due to various configurations and remarkably reducing processing costs.
