Image Generation and Display

A variety of methods and systems have been developed for 3D display [19,56,63,65]. But as previously noted, display and visualization are not fully synonymous. Visualization of 3D biomedical volume images has traditionally been divided into two different techniques: surface rendering [7,15,20,21, 34,54] and volume rendering [6,11,26,31,48,54,57]. Both techniques produce a visualization of selected structures in the 3D volume image, but the methods involved in these techniques are quite different, and each has its advantages and disadvantages. Selection between these two approaches is often predicated on the particular nature of the biomedical image data, the application to which the visualization is being applied, and the desired result of the visualization.
