Complex musculoskeletal anatomy: analysis using three dimensional surface reconstruction.

A new computer method has been developed that allows the reprocessing of standard CT scans to produce three dimensional surface images. The process requires only standard CT scanner hardware, and reconstruction time is comparable to that of sagittal and coronal reconstruction. Case reports illustrate the uniqueness of the perspective provided by this technique and its usefulness in clarifying areas of complex musculoskeletal anatomy. Surface images are especially valuable in conveying information to nonradiologist physicians who are unaccustomed to evaluating the numerous images produced in a standard CT scan.
