To still take straight quadrangular as example below, the Thickness Design of inclination angle of the present utility model and straight quadrangular part is described in conjunction with several specific embodiments.
Embodiment mono-:
Design a clinical PET detector, the packaging of photoelectric device surface area of use is 4x4mm
2, effectively working area is 3x3mm
2, predetermined detector take that to pursue high time resolution be object.Commercial clinical PET is used the conventional common thickness of LYSO crystal between 20～35mm at present, it is too little that sensitivity is too low cannot meet detection requirement, it is too large that crystal is too thick causes light photon transmission loss in crystal excessive, energy resolution and temporal resolution all can decline, here because detector is pursued high time performance, crystal general thickness is set as to 20mm～22mm.Meanwhile, for the ray energy that guarantees that monoblock crystal need to be surveyed for 511KeV(PET) sensitivity of ray, straight quadrangular thickness is generally set in 10～17mm.Crystal taper platform segment thickness=gross thickness-straight quadrangular thickness=3～12mm, the larger bottom surface of taper platform need to conform to for 4x4mm with packaging of photoelectric device surface
2, less bottom surface conforms to for 3x3mm with photoelectric device useful area
2.As shown in Figure 7, can calculate: inclination angle=arctan(taper platform thickness/(packaging of photoelectric device surface the length of side-photoelectric device photoelectric surface the length of side)), at 4 degree between 18 degree.
Embodiment bis-:
Design a nuclear radiation detector, using packaging of photoelectric device surface area is 6x6mm
2, effectively working area is 3x3mm
2, predetermined detector is pursued high sensitivity.In order to improve the detection efficiency of detector to high-energy ray, the gross thickness of crystal is set to 38～40mm, and the thickness of straight quadrangular is set to 30～35mm.In like manner can calculate: inclination angle at 17 degree to 45 degree.
The impact of the feature that can infer thus photoelectric device on crystal inclination angle and straight quadrangular thickness:
The useful detection area of photoelectric device and the ratio of its package area are less, and crystal inclination angle can be larger, straight quadrangular thickness=crystal gross thickness-taper platform segment thickness, and taper platform segment thickness becomes inverse correlation with crystal inclination angle.
The impact of the utility model detector pre-determined characteristics index on crystal inclination angle and straight quadrangular thickness:
If request detector energy resolution is high, light output is large, and crystal inclination angle need to reduce so, reduces the light that is tilted face reflection and consumes; If request detector is highly sensitive, the general thickness of crystal needs to increase so, and straight quadrangular thickness also can increase.While requiring at the same time at these 2, the inclination angle scope of crystal is at 2 degree between 15 degree, and straight quadrangular thickness is between 10 to 30mm.
