Description
Technical field
The present invention relates to scintillation crystal encapsulation technology field, more particularly to a kind of scintillation crystal array and scintillation crystal array
Method for packing.
Background technology
Positron emission tomography (Positron Emission Tomography, PET) technology is to utilize to detect certain
A pair of gamma-rays that the negatron in positive electron and organism that isotope decay is produced is buried in oblivion and produced are planted, biology is obtained
Internal this Nuclear analysis information, the 3 Dimension Image Technique of image reconstruction is completed using modern computer.Due to constituting life
Basic element C, O, N etc. have the isotope of transmitting positive electron, therefore, PET in theory can be to many positions of life entity
Physiological function be imaged.It can be seen that, PET is the quite distinctive instrument of life science, medical diagnosis.PET system is by visiting
Survey device, data collecting system, image reconstruction and the part of image procossing three composition.Pet detector design should meet claimed below:
(1) high sensitivity, the detection efficient to 511keV gamma-rays pair is high；(2) high spatial resolution, more accurately determines and buries in oblivion position
Put；(3) good temporal resolution, eliminates random coincidence event；(4) good energy resolution, eliminates Compton scattering
Influence；(5) it is cheap；(6) time is short；(7) stability is good.Pet detector is usually by scintillation crystal and photomultiplier
(location-sensitive photomultiplier or semiconductor devices) is coupled to form.Positron e mission computed tomography, is core doctor
The more advanced clinical examination image technology in field.Its substantially method is, by certain material, usually in biological life metabolism
After short-life radionuclide on necessary material, mark, injection human body, by the aggregation for the material in metabolism,
To reflect the situation of vital metabolic activity, so as to reach the purpose of diagnosis.Contrast imaging detector is the technological core of the technology
