Segmentation of Liver Tumor in CT Image Based on DICOM Format
Xiaoyang Huang · Computer Technology and Development · 2008
For reducing data loss and proceeding time,liver tumor is directly segmented from thorax and abdominal part in CT image based on DICOM format.Proper window width and window center are set first for efficient segmentation.ITK software is used to read the image,and curvature flow smoothing filter is used to denoise the image.Several histogram and region growing segmentation algorithms requently applied in image segmentation field are discussed,and also experimented combined with vivo CT image.Finally satisfied and effective result is obtained, which shows that the area of liver tumor in the image is small,so the target can be availably segmented by confidence connected threshold method in region growing.
