数字化虚拟肝脏图像三维重建的初步研究

Study of three-dimensional reconstruction of digitized virtual hepatic images

目的 研究数字化虚拟肝脏三维重建的方法。方法 数字化虚拟中国人女性I号(virtualchinesehumanfemaleNo 1,VCH F1)肝脏数据集中DSCF2 5 11 2 5 2 0连续图像 ,采用三维重建插值算法生成三维立体图 ,根据切片图像各点的颜色和位置特征 ,自动判断肝脏实体和肝脏管道的位置 ,并以不同的颜色进行显示。结果 肝脏实体部分显示较强的立体感 ,通过上下左右不同层面的旋转 ,可获得各种立体形态的图像和肝脏管道结构。结论 数字化虚拟中国人女性I号肝脏数据集图像精确 ,三维重建插值算法生成肝脏和肝脏管道三维图像清晰 ,是理想的三维重建方法。

Objective To study the methods of three-dimensional reconstruction of digitized virtual hepatic. Methods Images of DSCF 2511-2520 were taken from the database of digitized Virtual Chinese Human female No.1 (VCH-F1).Method of insertion value algorithm of three-dimensional reconstruction was used to make three-dimensional block diagram.In ordering to auto-judge the position of hepatic solid and hepatic ducts,these images were shown with different colors according to the character of color and location of every spot. Results Stereo image of hepatic solid could be shown satisfactorily. Every shape of stereo image and the structure of hepatic duct could be shown by revolving the three-dimensional image with different direction. Conclusions The image of hepatic database of digitized Virtual Chinese female No.1 was exact.The three-dimensional image of the liver and hepatic duct made by insertion value algorithm of three-dimensional reconstruction were distinct,and it was a ideal method of three-dimensional reconstruction.
