Volume rendering is a set of techniques used to describe and hence represent the visualization of three-dimensional data. Visualizing sampled functions of three spatial dimensions by computing 2-D projections of the entire volume data. Computed Tomography (CT) Volume Rendering, performs rendering of the CT medical data. This paper elaborates the techniques such as maximum intensity projection and shaded surface display that provide added diagnostic capabilities thereby providing much better visualization of the volume data.rnThe paper also focuses on a new emerging application of the computed tomography volumetric rendering that is 3D CT Volume Rendering. Its implementation involves volume data management including acquisition, resampling and editing, rendering parameters including window width and levels and image display comprising of techniques such as fly-through and fly-around.
