An efficient method of volume rendering for medical slices

The volume rendering method uses a special light source, slit-light source, to illuminate the volume and simulates the interactions of light with objects, such as light absorption, scattering and reflection. In comparison with previous methods, our method has several advantages. This includes flexibility for implementation, efficiency for computation, high reality for display and easiness of parallelization. The algorithm can be parallelized easily either using the data space subdivision method or the image space subdivision method. We describe some experimental results of applying our method to several sets of MRI and CT slices of human heads, which show the effectiveness of our method
