Optimization of 2D CT Data Sets for Three-Dimensional

Computer-generated anatomic modeling using radiologic data is a well-known entity. Currently, state of the art 3D modeling systems lack the variable thresholding, user interactive, capabilities of 3D imaging software.1 We investigated clinical parameters - cr scan plane, 2D filter algorithm, surrounding medium - and tested a simple mathematical thresholding algorithm based upon experimentation with a cr phantom, to evaluate a semiautomated approach to 3D craniofacial imaging and model generation.
