Embodiment Construction

[0023] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is said to be "fixed" to another element, it may be directly on the other element, or there may be one or more intervening elements therebetween. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or one or more intervening elements may be present therebetween. The orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", and "bottom" used in this specification is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the The invention and the simplified description do not indicate or imply that the device or element referred to must have a specific orientation...

Abstract

The invention relates to the technical field of image processing, in particular to a medical image processing method, which comprises the following steps of: sampling an original medical image to obtain a sampled image; and constructing a two-dimensional Gaussian filtering template, a direction filter, an enhancement filter and a general filter based on the sampled image so as to combine the target noise reduction image, the image with reduced pseudo edge points and the original medical image to obtain a processed target medical image. According to the medical image processing method providedby the embodiment of the invention, a two-dimensional anisotropic filter template is constructed by using a differential operator, and the template can be adaptive to high-frequency edge detail information of a multi-angle matching image; and the template is not restricted by factors such as the size and the shape of the filtering window, so that the defect of high-frequency information loss caused by filtering processing of an existing filter is greatly reduced, the background noise is reduced, the image tissue contrast ratio is also improved, and the image enhancement effect is more obvious.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a medical image processing method, device and system. Background technique [0002] When imaging with magnetic resonance technology, the image contrast will be deteriorated due to some interference, such as background noise, artifacts, boundary blur effects, etc., which will affect the doctor's subjective judgment, so the original image obtained by scanning often needs to be filtered to achieve Image enhancement. Blur enhancement is applied to the image through a template, and image information will be lost during denoising, especially edge details; sharpening enhancement is to extract the gradient operator of the image to enhance edge information and highlight the contrast of each tissue. [0003] The existing magnetic resonance image filter enhancement technology uses filter templates or traditional digital filters to act in the spatial domain to achieve the p...
