Abstract

The invention relates to a medical image noise reduction method and device, and the method comprises the steps: obtaining the scanning data of a scanning object, reconstructing a medical image of thescanning object according to the scanning data, obtaining a pharmacokinetic parameter image according to the scanning data and / or the medical image, and obtaining a reference image according to the medical image, and finally, denoising the pharmacokinetic parameter image according to the reference image to obtain a denoised pharmacokinetic parameter image. According to the invention, the method solves problems in the related technologies that the image features calculated according to the pharmacokinetic parameter image are not accurate enough and the noise reduction effect is poor because thenoise level of the pharmacokinetic parameter image is higher, maintains the focus contrast and contour clearness, and reduces the noise of the pharmacokinetic parameter image.

Description

technical field [0001] The present application relates to the technical field of medical imaging, in particular to a method and device for denoising medical images. Background technique [0002] The clinical examination imaging technology in the medical field needs to label the substances necessary for the metabolism of biological life, such as glucose, protein, nucleic acid, fatty acid, and short-lived radionuclides. Gather to reflect the situation of life metabolic activities, so as to achieve the purpose of diagnosis. When using imaging equipment to analyze the pharmacokinetic (Pharmacokinetic) parameter image of the metabolic model of the substance injected into the human body, the noise of the pharmacokinetic parameter image is often greater than that of the static image, which in turn affects the doctor's judgment on the lesion and a judgment on the accuracy of the metabolic model. [0003] In the related art, the noise reduction of the pharmacokinetic parameter imag...
