Abstract

The invention provides a light guide test device comprising a radioactive source box, a crystal holder, a photomultiplier tube box and a bottom plate which are connected sequentially from top to bottom. The radioactive source box comprises a radioactive source, a radioactive source box cover and a radioactive source box body. The crystal holder comprises a crystal holder body, a crystal holder cover, a crystal holder fixing plate, a crystal module and a to-be-detected light guide. The crystal holder body is fixed above the to-be-detected light guide through the crystal holder fixing plate. The to-be-detected light guide is fixed above the photomultiplier tube box through a plurality of spring clips. The photomultiplier tube box is fixed on the bottom plate. The photomultiplier tube box is internally equipped with a plurality of photomultiplier tubes. The photomultiplier tube box is externally equipped with a connector board which is provided with high-voltage power input ends and data output ends. The high-voltage power input ends are connected with the power input ends of the photomultiplier tubes. The signal output ends of the photomultiplier tubes are connected with a detector test platform through the data output ends.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a light guide testing device. Background technique [0002] Positron Emission Tomography (PET, Positron Emission Tomography) is a relatively advanced clinical examination imaging technology that applies computed tomography technology to the field of nuclear medicine after X-ray tomography and magnetic resonance imaging technology. The new imaging technology of molecular metabolism, receptors and neurotransmitter activities has been widely used in the diagnosis and differential diagnosis of various diseases, disease judgment, curative effect evaluation, organ function research and new drug development, etc. [0003] A PET scanner is composed of a detector, front-end electronics, an examination bed, a computer and other auxiliary parts, and the detector is the core component of PET and the "eye" of PET. The technical indicators of a PET scanner, such as position resolution, time...
