Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] as attached figure 1 As shown, a multifunctional scintillation crystal test platform includes a base 1 , a replaceable test stand 2 and a cassette 5 . The main function of the base 1 is to supply power to the replaceable test bench 2, obtain the data collected by the replaceable test bench 2, and send the data to the computer through the USB data interface 6 after processing the data. Specifically, the base 1 includes signal readout Output and power supply circuit, the replaceable test bench 2 is set on the base 1, and the replaceable test bench 2 is connected with the signal readout and power supply circuit. The replaceable test bench 2 is composed of a silicon photomultiplier tube array and a light guide through an optical coupling agent, and the measured crystal 3 is arranged above the light guide through air coupling; a large LYSO bracket 4 is embedded insi...

Abstract

The invention discloses a multifunctional scintillation crystal testing platform comprising a pedestal, a replaceable testing stand, and a hidden box. The pedestal is mainly used for providing power for the replaceable testing stand, obtaining data collected by the replaceable testing stand, processing the data and then sending the data to a computer through a USB data interface. The replaceable testing stand is formed by cooperation of a silicon photomultiplier array with different light guides by an optical coupling agent. Tested crystals are arranged above the light guides by on air coupling. A large LYSO support is embedded into the hidden box and is used for placing an LYSO crystal block needed by testing. On the basis of a new-generation solid photoelectric sensor SiPM technology, no radioactive source is needed and performances of crystals with different sizes and forms can be measured rapidly and precisely by replacing different light guides, wherein the crystals include a single crystal bar, single crystal arrays with different sizes, a plurality of crystal arrays with standard dimensions, and a plurality of crystal line arrays and the like. With the platform, the crystal product yield of crystal manufacturers can be improved substantially and the production cost and crystal products can be lowered.

Description

technical field [0001] The invention relates to the technical field of nuclear radiation detection, in particular to a multifunctional scintillation crystal testing platform. Background technique [0002] Scintillation crystals (such as BGO, LYSO, GSO, etc.) are the key materials for the detectors of large-scale medical equipment positron emission tomography. With the rapid development of the medical equipment industry in recent years, the demand for scintillation crystal materials has exploded. More and more crystal material manufacturers are involved in the development and production of scintillation crystals, and urgent problems also arise: because crystal material manufacturers have very limited understanding of radiation detection, crystal performance cannot be judged by themselves in the process of material research and development, and often require It is acceptable to entrust an external agency to assist in testing a small number of samples, but it is difficult to ju...
