Abstract

The invention relates to a PET equipment correction method, and the method comprises the steps: obtaining background radiation data which is received by a detector and comes from the detector crystalradiation particles; analyzing the background radiation data to obtain a first corrected image; inputting the first corrected image into a trained neural network model to obtain a second corrected image; and correcting the PET equipment according to the second corrected image. According to the PET equipment correction method and device, the computer equipment and the storage medium, the correctedimage obtained by the background radiation data is enhanced through the neural network, so that the problem of poor accuracy of the background radiation data is solved, the use of a radioactive sourceis avoided, the radiation dosage of a doctor is reduced, and the use cost of a hospital is reduced.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a PET equipment calibration method, device, computer equipment and storage medium. Background technique [0002] Positron Emission Computed Tomography (PET, Positron Emission Computed Tomography) is a relatively advanced clinical examination imaging technology in the field of nuclear medicine. The general method is to inject a certain substance, which is generally a necessary substance in the metabolism of biological life, such as glucose, protein, nucleic acid, fatty acid, and a short-lived radionuclide (such as F18, carbon 11, etc.) into the human body. , through the accumulation of the substance in the metabolism, to reflect the situation of life metabolic activities, so as to achieve the purpose of diagnosis. Positron emission computed tomography is more widely used because of its high sensitivity, high specificity and good safety. During the use of the PE...
