Description
Technical field
The present invention relates to positron emission tomoscan (PET, positron emission tomography) technical field, more specifically, the PET detection system that relates to a kind of photoconduction and use this photoconduction.
Background technology
In recent years, in the Medical Physics field, the application of PET detector more and more widely.In PET uses, require energy, and hit position of detector and measure accurately, to determine the physiological processes of radioactive nucleus position and quantification human body to a pair of gamma ray that produces behind the positron annihilation.
Present topmost PET panel detector structure is that scintillation crystal array adds by photomultiplier (Photomultiplier tube, PMT) the electrooptical device array of Gou Chenging, ray sends fluorescence after hitting scintillation crystal array, after being amplified by the absorption of electrooptical device array, obtains electric signal.From PET panel detector structure angle, the flatness of scintillation crystal array and the coupling of electrooptical device array is good more, the luminous energy that sends from scintillation crystal array by the electrooptical device array catch many more, the efficient of the detection of PET detector is high more, measuring error is also more little.Therefore, the degree of coupling of scintillation crystal array and electrooptical device array is one of key factor that influences PET detection system detection efficiency.
The main design proposal of PET detector has following three kinds at present:
1, adopts circular photomultiplier, and the edge offset of scintillation crystal array and photomultiplier alignment, such one 8 * 8 scintillation crystal array needs the different quadrants of four of 4 photomultipliers to cover, and this design proposal is the main flow method for designing of present PET detector.The benefit of this design proposal is the number that can significantly reduce the required photomultiplier of total system, reduces system cost, and shortcoming is that the part detection area of the photomultiplier that is not covered by scintillation crystal array on the edge will be wasted.
2, adopt square photomultiplier to form the electrooptical device array, the alignment of the same employing mostly of the alignment thereof of electrooptical device array and scintillation crystal array edge offset.Because square electrooptical device array can be covered by square scintillation crystal array fully, therefore the benefit of this programme is that theoretical detection efficiency is the highest, but because the processing of square photomultiplier causes the system cost of this programme very high than the processing difficulties of circular photomultiplier.
3, adopt the crystalline material of differential declines time to form the mixed crystal array.Hybrid mode can be that each single crystal all is spliced by different materials, and perhaps single crystal is made up of same material, but whole crystal array is made up of different materials.The benefit of this scheme is by the careful selection to material, and photoyield (energy) difference in the time of might making photon hit the diverse location of crystal array is very big, improves the resolution characteristic of PET detection system; But the assembling inconvenience of mixed crystal array, and because the physical characteristics (such as aging characteristics) of different materials is inconsistent, the time has been grown may be owing to reasons such as system aging are brought than mistake to result of detection.
The also favourable scheme that improves the detection efficiency of PET detection system with photoconduction connection scintillation crystal array and PMT array in the prior art, as publication number is CN1186246A and CN101182133A Chinese patent application, but in the disclosed technical scheme of this open text, photoconduction (device) just utilizes light that the light signal on the scintillation crystal array is guided to photomultiplier, with scattering and the interference from outside signals of avoiding signal, though the application of this photoconduction can improve the resolution and the sensitivity of PET detector, but its cost is too high, on the other hand, these two kinds of schemes are not all explored potential location of photoconduction and assembling function, and the mechanical couplings between scintillation crystal array and the electrooptical device array is not had help.
