Embodiment Construction

[0017] A digital X-ray image processing device, which includes an image decomposition module, a signal processing module, an image synthesis module, and an input interface for obtaining external image information. The image decomposition module can perform 4 / 9 sampling on external images to obtain different resolutions The acquired external image is decomposed into different levels of details; the signal processing module uses Log operation to equalize the signals on the above-mentioned levels of details, amplifies the signal with smaller gain, suppresses the signal with larger gain, and uses Multi-level Gaussian filtering suppresses the noise distributed in different frequency bands in the image.

[0018] The digitized X-ray image processing method of the present invention adopts the idea of ​​multi-resolution to process the image. The method first uses an improved pyramid algorithm to decompose the original digitized X-ray image into details of different levels (the input ima...

Abstract

The invention relates to field of medical image, which in detail relates to a device and method for treating image of digitalized X line. The said device comprises: image disintegrating module, signal treating module, image synthesizing module and input interface for getting external image information. The image disintegrating module can take 4 / 9 sample for external image and get image under different distinguishability to disintegrate the external image into detail with different gradation; said signal treating module treats signal of said detail in balance by using Log calculation, enlarges signals with small transmission gain and inhibits signals with large transmission gain; said signal treating module uses multiple layer Gaussian filtration to inhibit the noise distributed in different frequency range.

Description

technical field [0001] The invention relates to the field of medical imaging, and relates to a digital X-ray image processing device and method. Background technique [0002] X-ray photography is an important means of medical diagnosis, and digital X-ray images have greater advantages than X-ray film. Digital X-ray images have significant advantages such as large dynamic range and good image linearity. However, the grayscale resolution of the human eye is limited, and it is difficult to see all the image information under one observation condition. The image must be adjusted repeatedly, and different window widths and levels are used for different parts to ensure that important diagnoses are not missed. information. The doctor who reads the film must have a lot of experience to make full use of the advantages of digital X-ray images through image adjustment. At the same time, image adjustment is a time-consuming and skillful work. The traditional image processing method i...
