Systems for PET imaging
View Patent ↗The present disclosure relates to a system for PET imaging. The system may include a first device and a second device. The first device may include a first scanning channel. The second device may include a second scanning channel connected to the first scanning channel, a heat generating component, and a cooling assembly configured to cool the heat generating component, wherein the cooling assembly may include an inlet chamber and a return chamber, the heat generating component may be closer to a first side of the second device than at least one of the inlet chamber or the return chamber, and the first side of the second device may face the first device.
1. An imaging system, comprising:
a detector assembly including a plurality of detector modules;
a gantry assembly including a main gantry and a gantry base, wherein the gantry base is configured to support the main gantry, and the detector assembly is mounted on the main gantry; and
a cooling assembly including a cooler, a chilling chamber surrounding the plurality of detector modules, an inlet chamber, and a return chamber, wherein the inlet chamber is in fluid communication with the chilling chamber, the return chamber is in fluid connection with the cooler, the inlet chamber and the return chamber have a common plane, and the common plane includes a first thermal insulation layer.
2. The system of claim 1 , wherein the inlet chamber and the return chamber are integrated on the main gantry.
3. The system of claim 2 , wherein the common plane faces the plurality of detector modules, and an air intake of the inlet chamber in fluid communication with the chilling chamber and an air outlet of the return chamber in fluid communication with the chilling chamber are formed on the common plane.
4. The system of claim 3 , wherein the chilling chamber includes at least one clapboard configured to divide the chilling chamber into a plurality of sub chambers according to the number of the plurality of detector modules, and each of the plurality of sub chambers includes an air intake of the inlet chamber and an air outlet of the return chamber.
5. The system of claim 1 , wherein an inlet chamber port of the inlet chamber in fluid communication with the cooler and a return chamber port of the return chamber in fluid communication with the cooler are formed on a coplane facing the detector assembly.
6. The system of claim 1 , wherein a plane other than the common plane between the inlet chamber and the return chamber includes a second thermal insulation layer, or a sidewall of the chilling chamber includes a third thermal insulation layer.
7. The system of claim 1 , wherein the cooler includes a compressor chamber or an air supply chamber, and a sidewall of the compressor chamber or the air supply chamber includes a fourth thermal insulation layer.
8. The system of claim 1 , wherein the chilling chamber is a confined chamber.
9. The system of claim 1 , wherein the first thermal insulation layer includes insulated cotton.
10. An imaging system, comprising:
a gantry assembly including a main gantry and a gantry base configured to support the main gantry;
a heat generating component mounted on the main gantry;
a cooling assembly configured to cool the heat generating component; and
a sliding device configured underneath the cooling assembly to facilitate mounting of the cooling assembly.
11. The system of claim 10 , wherein the sliding device includes a sliding piece and a supporting plate configured to support the cooling assembly.
12. The system of claim 11 , wherein the sliding piece includes a wheel assembly.
13. The system of claim 11 , wherein the gantry base includes a guide component configured to coordinate with the sliding piece of the sliding device.
