Problems solved by technology

In order to obtain high-quality PET images, the full dose of radiotracer is very necessary, but the full dose of radiotracer will cause potential patient health problems
Moreover, simply reducing the dose of the MIP image will reduce the quality of the MIP image due to more noise, which cannot meet the quality requirements of the reference image.

Embodiment Construction

[0044] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0045] The enhancement method of low-dose MIP images provided in this application can be applied to such as figure 1 in the application environment shown. The terminal 1 communicates with the server 2 through the network through the network. The first MIP image and the corresponding first PET image are reconstructed in the terminal 1, and the second MIP image under the low-dose radioactive tracer corresponding to the body position is obtained; according to the first MIP image and the second MIP image, a generative adversarial neural network is used to establish Image...

Abstract

The present application relates to a low-dose MIP image enhancement method, device, computer equipment and storage medium. The method includes: acquiring the first MIP image and the corresponding first PET image under the full-dose radioactive tracer, reconstructing the first MIP image and the corresponding first PET image, and obtaining the first MIP image under the low-dose radioactive tracer corresponding to the body position. Two MIP images; use the generated confrontation neural network to learn the second MIP image through the feedback of the first MIP image, and establish an image enhancement model; obtain the current MIP image under low-dose radioactive tracer, and input the current MIP image into the image enhancement The model performs image enhancement and outputs a MIP-enhanced image. By using the method, the image enhancement model can be used to quickly output a high-quality MIP enhanced image; thus, the quality requirement of the low-dose MIP image as a reference image can be met.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, to a low-dose MIP image enhancement method, apparatus, computer equipment and storage medium. Background technique [0002] Direct volume rendering (DVR) is one of the most effective volume data visualization methods, and is widely used in many fields such as medicine, geography, and physics. Transfer function (TF) is responsible for mapping volume data attributes (such as density value, gradient mode, etc.) to optical attributes such as color and transparency, and its quality has a decisive influence on the effect of DVR. As a special DVR method, maximum intensity projection (MIP) projects the maximum density value of the projected light onto the screen without transfer function, and has the advantages of simplicity and practicality, and is widely used in medicine and other fields. [0003] In a PET-MR device, it is necessary to generate a set of PET images...
