Abstract

A kidney multiperiod CT image fusion system disclosed by the present invention comprises an image acquisition device used for obtaining the kidney CT images, a pre-processing device for denoising andenhancing the kidney CT images, a primary registration device for grouping the kidney CT images, a multi-phase fusion device for fusing the kidney CT images to realize the information complementationbetween the kidney CT images of different phases, a three dimensional reconstruction device for generating the specific kidney three dimensional images based on the fused images and a kidney databasefor classifying and storing the specific kidney three dimensional images. The multi-phase fusion device comprises a linear weighting fusion unit, a high-pass filtering fusion unit and a wavelet fusionunit, the linear weighting fusion unit multiplies the corresponding pixel values in the kidney CT images by a weight coefficient separately and then adds together to obtain the fused images, the high-pass filtering fusion unit superposes the high-frequency components of a high-resolution image to a low- resolution image to obtained the fused images, and the wavelet fusion unit carries out the wavelet decomposition and then the inverse wavelets transform on the kidney CT images to obtain the fused images.

Description

technical field [0001] The invention relates to the technical field of medical image processing, in particular to a multiphase CT image fusion system. Background technique [0002] Image fusion (Image Fusion) refers to the image data collected by multi-source channels about the same target through image processing and computer technology processing, etc., to maximize the extraction of beneficial information in each channel, and finally synthesize high-quality images. In order to improve the utilization rate of image information, improve the accuracy and reliability of computer interpretation, improve the spatial resolution and spectral resolution of the original image, and facilitate monitoring. The image to be fused has been registered and the pixel bit width is consistent, and the information of two or more multi-source images is synthesized and extracted. The efficient image fusion method can comprehensively process the information of multi-source channels according to t...
