In this thesis , some key issues of the vr technique are systematically investigated . firstly , for the image filters and image interpolation between slices , a integrated interpolation algorithm is presented based on the contour shape and correspondence matching , which keeps the shapes and grays information the objects of interest . secondly , the fidelity of effect of the vr for medical images is studied , and a continuous - gradient - based method for transparent volume rendering is proposed , which vivifies the results of volume rendering 首先，研究了医学断层图像数据的滤波及层间插值技术，提出了一种基于轮廓形变和对应点匹配相结合的混合插值算法，在实现图像层间插值的同时保持了目标的轮廓形状与灰度信息；其次，对医学影像容积重建效果的逼真度进行了研究，提出了一种基于连续梯度转换函数的交互式透明体绘制方法，使重建效果更加生动、真实。
