Embodiment Construction

[0044] In the medical image processing process based on the multi-resolution spatial data model, the present invention performs segmentation noise suppression and structure enhancement on the detail image, and performs image equalization processing on the residual value image to enhance the suppressed structure in the original image Information can improve the visual effect of medical images and reduce the missed diagnosis and misdiagnosis caused by the suppression of structural details in the original image.

[0045] refer to figure 1 In a preferred embodiment shown, the medical image processing method proposed by the present invention is suitable for post-processing of most medical images, such as ultrasound B-mode images, X-ray fluoroscopy images, magnetic resonance images and CT images, etc. Specifically, the medical image processing method proposed by the present invention is implemented as follows:

Abstract

The invention discloses a method and a system for processing medical images, wherein the method for processing the medical images comprises the steps of: using a multi-resolution spatial data model to convert and decompose the input original medical image into multiple scales to obtain a series of detailed images in different resolutions, and a residual value image; enhancing the residual value image by a histogram equalization method to obtain a new residual value image; orderly suppressing noise and processing gains for each pixel in the detail image of each layer from the detailed image with minimal scale so as to respectively obtain new detail images; and reconstructing the new residual value image and the new detailed image of each layer through a reconstruction algorithm to obtain the processed new medical image. By the method and the system provided by the invention, damage on image structure information during noise suppression is avoided, noise suppression and structure enhancement are conducted selectively, and the granularity of the reconstructed image is kept when the noise is suppressed, so that the output medical image has a good visual effect.

Description

technical field [0001] The invention relates to an image processing technology, in particular to a method for performing noise reduction and enhancement processing on medical images, and a processing system using the processing method. Background technique [0002] With the development and progress of medical imaging technology, image processing is more and more widely used in medical research and clinical medicine. [0003] Due to the requirements of acquisition source, exposure parameters and dose, medical images are often disturbed by noise, which degrades the image quality and covers some important tissue lesions, which brings great difficulties to doctors in diagnosing and identifying certain diseases. difficulties, and there is a risk of missed and misdiagnosed. In this patent, by applying a multi-resolution spatial model, a medical image post-processing method is implemented to improve the visual effect of the image and enhance the structural detail information in th...
