Abstract

The invention relates to a PET image noise reduction method and device and computer equipment, and the method comprises the steps: obtaining a first PET image and a second PET image, wherein the second PET image is a PET image after the noise reduction of the first PET image; acquiring the compensation pixel point information from the first PET image; compensating the second PET image according tothe compensation pixel point information to obtain a third PET image. According to the method and the device, the problem that the maximum values of the standard shooting values of the PET image before and after noise reduction are inconsistent in the prior art is solved, and the condition that the maximum values of the standard shooting values of the PET image before and after noise reduction are reduced is improved.

Description

technical field [0001] The present application relates to the field of medical imaging, in particular to a PET image noise reduction method, device and computer equipment. Background technique [0002] Standard Uptake Value (SUV for short) is a semi-quantitative index commonly used in tumor diagnosis by positron radiation procedures, which refers to the ratio of the radioactive activity of imaging agents taken up by local tissues to the average injected activity of the whole body. According to the different regions of interest in its measurement, it can be divided into the following types: the maximum standard uptake value (referred to as SUVmax), defined as the SUV of a single pixel with the highest uptake level within the target area, which is not affected by the region of interest Influenced by delineation method, but disturbed by statistical fluctuations in radioactivity counts. The standard uptake mean value (SUVmean for short) is defined as the mean value of SUV in al...
