In order to efficiently reconstruct 3D medical image and clearly display the detailed information of inner structures and the inner hidden interfaces between different mediums

an improved volume rendering optical model(IVROM) for translucent volume rendering is proposed

which can be easily realized on a general PC. On the basis of classic absorption and emission model

the effects of volumetric shadows

direct and indirect scattering are also considered in the proposed model Moreover

the implementation of the translucent volume rendering method incorporating the IVROM model and Shear-Warp is described detail. Experiments demonstrate the good performance of the proposed method.
