摘要:: 针对全心脏器官各组织在灰度分布上存在的复杂粘连和交错叠加现象，提出用自适应的几何切割刀具的刀刃边缘对不同组织进行切割或保留，在保持心外膜和心外膜脂肪完好的情况下对心脏外组织进行有效剔除，采用模拟手术刀切割方式的心脏分割方法和其他相关分析算法采用GPU编程方式实现。实验结果表明，本文方法可对复杂的胸部数据进行分割，得到全心脏和冠状动脉的实时细节显示，对心脏疾病的分析判断提供图像导视，此切割方法可应用于现有算法器官分割技术无法完全切除的残余组织提供快速的剔除。

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.
