Embodiment 1

[0030] figure 1 It is a schematic structural diagram of a PET imaging device according to Embodiment 1 of the present invention, refer to figure 1 As shown, in this embodiment, the PET imaging device includes a frame 110, the frame 110 is formed with a scanning channel 120 for accommodating patients, and a plurality of detector modules 130 are located in the scanning channel 120 and along the PET scanning channel 211 Evenly arranged in the circumferential direction, it also includes a heat conduction component for conducting the heat generated by the detector module 130, and a cooling component for cooling the heat conduction component. In this embodiment, the heat conduction component includes a first part close to the detector module 130 and a second part away from the detector module 130 , the distance between the cooling component and the first part is greater than the distance between the cooling component and the second part.

Embodiment 2

[0042] The difference between this embodiment and the first embodiment lies in that the connection component is made of phase change material to realize the cooling of the detector module. The two sides of the support plate connecting the components are set in contact with the photodetection board and the front-end electronic circuit board respectively. Therefore, when the PET imaging device is working, the photoelectric detection board and the front-end electronic circuit board are used to dissipate heat by using the good thermal conductivity of the phase change material , quickly transferred to the fixed plate through the support plate. The cooling of the fixed plate is the same as that of the first embodiment, and will not be repeated here.

[0043] In this embodiment, the support plate and the fixed plate of the detector module are both made of phase change materials, the contact area between the support plate and the photoelectric detection plate and the front-end electro...

Abstract

The present disclosure relates to systems and methods for heat transfer and cooling in PET. The system may include a gantry including a gantry forming a detection tunnel; a detector mounted to the gantry, and positioned in a circumference of the detection tunnel; a heat transfer device thermally coupled with the detector and configured to transfer heat generated by the detector; and a cooling device thermally coupled to the heat transfer device, and configured to cool the heat transfer device.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a PET imaging equipment and a combined medical system. Background technique [0002] In modern nuclear medicine, PET equipment (Positron Emission Computed Tomography, Positron Emission Computed Tomography) is a relatively advanced clinical examination imaging equipment, which is usually used in combination with other medical imaging equipment, such as PET equipment and MR A combination of equipment (Magnetic Resonance, magnetic resonance scanning) forms a PET-MR equipment, and a combination of a PET equipment and a CT equipment (Computed Tomography, electronic computer tomography) forms a PET-CT equipment. . [0003] Taking PET-MR equipment as an example, the PET-MR equipment includes a frame, and the frame is formed with a scanning channel for accommodating patients; gradient coils and magnets arranged axially along the scanning channel on the frame, and a detector a...
