Problems solved by technology

A more commonly used cooling method is to directly pump out the air in the scanning room to take away the heat inside the machine, but this method cannot maintain the stability of the temperature in the scanning room, and it is difficult to ensure that the system runs at the best working temperature. It is easy to bring dust and impurities in the environment into the detector, affecting the imaging effect and system life

Abstract

The invention relates to the technical field of medical instruments, specifically to a cooling system used for a medical imaging device. The medical imaging device includes a detector module having a hollow cavity, a reading circuit board and a front-end processing unit are arranged in the hollow cavity. The cooling system includes a cooling air passage and a flow guide channel, wherein the cooling air passage includes an air inlet cavity and an air return cavity, the front-end processing unit is located in the air inlet cavity, and the reading circuit is located in the air return cavity; and the flow guide channel includes an air inlet channel and an air return channel arranged side by side, the air inlet channel is communicated with the air inlet cavity, the air return channel is communicated with the air return cavity, and a refrigeration device is used for conveying cooling air flow to the air inlet channel. According to the cooling system used for the medical imaging device, the reading circuit board is integrated in the detector, and a cooling circulation system is established, thereby improving stability of temperature inside the detector module, and the cooling system is compact in structure and reasonable in layout, thereby providing convenience for maintenance of the detector module.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a cooling system for medical imaging devices. Background technique [0002] Existing medical imaging technologies include Single-Photon Emission Computed Tomography (Single-Photon Emission Computed Tomography, SPECT), Positron Emission Tomography (Position Emission Tomography, PET) and other technologies. Medical imaging systems such as SPECT and PET include a channel for accommodating patients, and detectors surrounding the human body are arranged in the channel, so that multi-angle imaging pictures of human lesion tissues can be obtained, and more accurate lesion information can be obtained. [0003] The principle of positron emission tomography technology is: a positron emitted during the decay of positronium combines with free electrons in human tissue and annihilates, and transforms into two gamma photons with opposite directions and energy of 511KeV each. When ...
