Improvement on Dual Energy CT Reconstruction Algorithm from Incomplete Data Based on Image Segmentation
摘要
Abstract
Aimed at dual energy CT reconstruction algorithm from incomplete data based on image segmentation, this paper proposed two key points to improve this algorithm, the processes of image segmentation and solving the equations. The primary results demonstrate that these two elements greatly affect the quality of reconstructions. Hence, depending on the application requirements, if we can optimize these two key points, a more robust dual energy CT reconstruction algorithm from incomplete data based on image segmentation would be obtained.关键词
