Abstract

The invention discloses a radiography imaging detector scintillation crystal array which comprises scintillation crystal bars, a first barium sulfate coating, a second barium sulfate coating and an aluminum foil paper tape. A number of scintillation crystal bars form the scintillation crystal array through the first barium sulfate coating. The second barium sulfate coating and the aluminum foil paper tape respectively coat the outer surface of the scintillation crystal array. According to the radiography imaging detector scintillation crystal array and a manufacture method thereof, which are provided by the invention, the manufactured scintillation crystal array can acquire high light output, low light crosstalk, great position resolution and a great light isolation effect; and the radiography imaging detector scintillation crystal array and the manufacture method thereof have the advantages of assembly repeatability, low cost and good light collection and imaging effects.

Description

technical field [0001] The invention relates to the field of profiles, in particular to a contrast imaging detector scintillation crystal array and a manufacturing method thereof. Background technique [0002] Positron emission tomography (PET) is a non-invasive imaging technology that can reflect the imaging of molecular metabolism. When the disease is in the stage of molecular level changes in the early stage, the morphological structure of the disease area has not yet shown abnormality. Positron emission tomography The scanner can find the location of the lesion, and can obtain three-dimensional images for quantitative analysis, so as to achieve the effect of early diagnosis and early treatment. [0003] The design of the contrast imaging detector is a very important link in the development of the PET system. The module of the contrast imaging detector mainly includes two parts, namely the photoelectric conversion device and the scintillation crystal array. However, the ...
