Embodiment Construction
[0037] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0038] refer to figure 1 with figure 2 In this embodiment, a dehumidification device for a positron emission tomography system is provided. The dehumidification device includes: a housing that seals the detector 8, the housing includes an annular outer peripheral surface, and the annular outer peripheral surface is spliced by a plurality of planar plates 3 Composition, each planar plate 3 is provided with a through hole (not shown in the figure);
[0039] A dehumidification assembly 2 with a built-in desiccant is installed on the side of each planar plate 3 facing away from the detector 8. The dehumidification assembly 2 is a passive device, and the dehumidification assembly 2 communicates with the through hole to absorb the low temperature environment (whe...

The invention relates to a dehumidification device for positron emission tomography. The dehumidification device can achieve a dehumidification function without additionally arranging an active dehumidifier or corresponding pipelines. The dehumidification device comprises a shell for sealing detector, the shell comprises an annular peripheral face and an end face matched with the annular circumferential face, the annular peripheral face is formed by splicing a plurality of substructures, and a through hole is formed in each substructure. A dehumidification assembly with a drying agent arrangedinside is mounted on each substructure, the dehumidification assemblies are passive devices, and the dehumidification assemblies are communicated with the through holes to adsorb steam in the shell.
Description
technical field [0001] The invention relates to a dehumidification device for a positron emission tomography system and the positron emission tomography system. Background technique [0002] In the field of medical imaging, Positron Emission Tomography (PET) is playing an increasingly important role as a functional imaging device. PET is an imaging technology that non-invasively displays the function and metabolism of human organs. Its working principle is to label substances necessary for the metabolism of biological life, such as glucose, protein, nucleic acid, fatty acid, and short-lived radionuclides (such as 18F, 11C, etc.), injected into the human body, taking advantage of the different metabolic states of different tissues of the human body, for example, in high-metabolism malignant tumor tissues, the glucose metabolism is vigorous and gathers more, and these characteristics reflecting life metabolic activities are reflected through images, so as to achieve The purpo...
