ABSTRACT
Objective To study the extraction,registration and fusion of the image contour of liver CT scan sequence.Methods Filtering method was used to remove the noise and enhance the edge of the image,and then the contour of the CT image was extracted.According to the optimal registration parameters,the hepatic arterial phase and venous phase images were registered,and the corresponding relationship between the arterial and venous images was determined.At last,the CT images of the arterial and venous phase were fused.Results After fusing the corresponding arterial and venous images,condition of liver artery and vein of the same cross section in different phase periods could be observed.Conclusions Fused image can offer richer image information to doctors for diagnosis.
