Abstract:
In view of the complex adhesion and overlapping of whole heart image data on the luminance distribution,a novel adaptive geometric cutting tool for distinguished cutting or preservation of different tissues on the edge of the blade is proposed for efficiently eliminating the extra-cardiac tissues while preserving the epicardium and epicardial fat.The whole heart segmentation approach which simulate scalpel cutting and relative analysis algorithms are implemented by GPU programming.Experimental results demonstrate that the proposed method can provide virtual reality for whole heart and coronary artery details in real time from complex chest volume data,and offer graphic guiding for analysis and judgment of heart diseases.The proposed cutting method can be served as a quick culling tool for the organ remnant tissues which can't be appropriately segmented using the existing algorithms.
