Computed Tomography Cinematic Rendering in the Evaluation of Colonic Pathology: Technique and Clinical Applications
Three-dimensional (3D) visualizations of computed tomography (CT) data have found use in the display of complex anatomy and pathology. A new method of 3D CT image creation known as cinematic rendering (CR) makes use of a global lighting model to produce photorealistic images. Cinematic rendering images contain high levels of detail with shadowing and depth that are not available from traditional 3D CT techniques. As yet, the role of CR in evaluating colonic pathology has not been investigated. However, given the breadth of pathologic processes that affect the colon, including inflammatory bowel disease, diverticulitis, neo...
