OPTICAL SENSOR, GAMMA RAY DETECTOR, AND POSITIVE ELECTRON EMISSION COMPUTER TOMOGRAPHIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an optical sensor, a gamma ray detector, and a positive electron emission computer tomographic device which process light with digital signals.;SOLUTION: An optical sensor according to one embodiment includes: a photomultiplier tube; an analog-digital converter; a non-temporary storage part. The photomultiplier tube receives light and outputs analog signals corresponding to the received light. The analog-digital converter receives analog signals and generates digital signals from the received analog signals. The storage part stores parameters calculated during the operation of the photomultiplier tube. The photomultiplier tube, the analog-digital converter, and the storage part are incorporated into a single housing.;COPYRIGHT: (C)2013,JPO&INPIT
