Title:
FULL-ANGLE COINCIDENCE PET DETECTOR AND METHOD
Document Type and Number:
WIPO Patent Application WO/2019/214368
Kind Code:
A1
Abstract:
A full-angle coincidence PET detector array, comprising the following components: a plurality of PET detection modules (2), wherein each of the PET detection modules (2) is composed of PET detection crystals (7), a photosensor array (5) and a light guide (6); and the plurality of PET detection modules (2) are adjacent to each other to form an integrally closed detection chamber. A full-angle coincidence PET detection method, comprising the following steps: 1) the step of assembling the detection chamber; 2) the step of placing a detection object; and 3) the step of acquiring an image. The cross-sectional area of all voids is smaller than the area of the smallest of the PET detection crystals (7) when the detection chamber is in a closed state; and the integrally closed detection chamber is of a cylindrical shape, a capsular shape, an ellipsoidal shape or a regular polygonal prism shape.
