Problems solved by technology

However, the photomultiplier tube detector (PMT) and its signal processing unit have certain requirements on temperature. Excessive temperature will affect the time resolution, spatial resolution and other related performance of nuclear medicine diagnostic equipment, which will eventually affect nuclear medicine diagnosis. The quality of the image formed by the device

Abstract

The invention discloses a nuclear medicine diagnosis device and a cooling method thereof. The nuclear medicine diagnosis device comprises an outer cover, a machine frame, a plurality of detector unitsand a plurality of signal processing units; a cavity is formed by the outer cover and the machine frame for containing the detector units and the signal processing units. The cooling method comprisesthe following steps that: obtaining the current temperature value of each detector unit; comparing the current temperature value of each detector unit with a preset temperature value to obtain a detector unit of which the current temperature value is greater than or equal to the preset temperature value as a high-temperature detector unit; and cooling the high-temperature detector unit. The cooling method or a disclosed cooling device has a temperature detection control capability, so that the temperature balance of each detector unit is relatively high, and the imaging performance of the nuclear medicine diagnosis device is ensured.

Description

technical field [0001] The present application relates to the technical field of cooling, in particular to a nuclear medicine diagnostic device and a cooling method thereof. Background technique [0002] Nuclear medicine diagnostic devices are imaging devices commonly used in medicine, for example, single electron emission computed tomography (SPECT) devices, positron emission computed tomography (PET) devices, and the like. The nuclear medicine diagnostic device can form an image of the distribution of drugs containing radionuclides in the body, which can reflect the metabolism, tissue function and structure of the human body. [0003] In a nuclear medicine diagnostic device, the most core components are the detector unit and the signal processing unit. The detector unit and the signal processing unit are used to detect the radiation (eg gamma ray) emitted by the radionuclide introduced into the patient's body and process each signal. Commonly used detector units are main...
