Title:
NUCLEUS DETECTOR
Document Type and Number:
WIPO Patent Application WO/2019/019449
Kind Code:
A1
Abstract:
Disclosed is a nucleus detector, comprising a scintillation crystal array (10), a light guide (20) and a photoelectric detector array (30), wherein the scintillation crystal array (10) comprises several scintillation crystal strips (11) closely arranged in sequence and of the same size, the photoelectric detector array (30) comprises several photoelectric detectors arranged in sequence, the cross sectional area of the photoelectric detectors is greater than the cross sectional area of the scintillation crystal strips (11), the light guide (20) comprises a top face and a bottom face opposite each other and side faces, the top face of the light guide (20) is coupled with the scintillation crystal array (10), the bottom face of the light guide (20) is coupled with the photoelectric detector array (30), and the thickness of the light guide (20) is 0.1 mm to 40 mm. The light guide (20) further has slots (22, 23) provided near an edge of the light guide (20), the slots (22, 23) extend from the top face to the bottom face of the light guide (20), and the depth of the slots (22, 23) is 0.1-0.5 times the thickness of the light guide (22, 23).
