Primary liver cancer is one of the high degree malignancies, which surgical resection is preferred. Hepatectomyrnis a complicated operative procedure because of its anatomical complexity and invisibility, of vascular systems, the three-rndimensional(3d) reconstruction of liver based on CT data could show the vascular systems clearly and adjacent relationship ofrntumor.It contribute to increase success and safer of hepatectomy, and more curative precise hepatectomy and calculate the remnantrnliver volume.%原发性肝癌恶性程度高,治疗方案仍以手术为首选,但因肝脏管道系统复杂且不可见,手术难度较大,基于CT数据的肝脏三维重建可以清晰地显示管道系统走行及与肿瘤毗邻关系,有利于精准肝切除的实行和计算残肝体积,可提高手术成功率与安全性.
