Embodiment Construction

[0041]In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar extensions without violating the connotation of the present invention, so the present invention is not limited by the specific implementations disclosed below. Secondly, the present invention is described in detail by means of schematic diagrams. When describing the embodiments of the present invention in detail, for convenience of explanation, the schematic diagrams are only examples, which should not limit the protection scope of the present invention.

[0042] The ultimate goal of image denoising is to remove the noise in the image and obtain a clear original image as much as possible. In other words, while removing noise, the geometry of the image is preserved. Medical images pr...

Abstract

The invention discloses a medical image processing method and system. The method comprises the steps that a medical image to be processed is acquired, and the interested region of the medical image is extracted; filtering and parameter optimization are carried out on the interested region to acquire an optimal filtering parameter; the optimal filtering parameter is used to filter regions outside the interested region of the medical image; and the filtered medical image is output. According to the technical scheme, the optimal filtering parameter is acquired from the interested region; the optimal filtering parameter is applied to global image filtering; and the method has the advantages of stable filtering effect, consistent whole image noise reduction and fast processing speed. In addition, the invention further provides a medical image processing system.

Description

technical field [0001] The invention relates to the technical field of medical images, in particular to a medical image processing method and system. Background technique [0002] In recent years, with the development and progress of medical imaging technology, image processing has become more and more widely used in medical research and clinical medicine. Medical images play an important role in modern disease diagnosis. When analyzing and reading gray-scale medical images, image contrast, edge features, and signal-to-noise ratio are very important to the correctness of diagnosis. However, due to various factors such as the imperfection of imaging equipment, transmission media and recording equipment, and the influence of imaging objects, problems such as noise, blur, and artifacts will inevitably occur during the generation of medical images; The processing link will also introduce noise interference, which often manifests as structural abnormalities such as isolated pixe...
