Helical CATSCAN 3-D reconstruction for diagnosis, planning, navigation and therapy of urologic disorders

Summary form only given. New slip ring technology has transformed conventional two dimensional computerized axial tomographic methods into three dimensional imaging. Such methodology has allowed visualization, analysis, orchestration, subtraction and application of volumetric data towards therapeutic ends. It is important that engineers and physicians speak in common denominators for satisfactory end points, considering the rapid developments in imaging and computer technology. This abstract and the accompanying video of 3-D helical CATSCAN reconstruction are oriented to discuss the medical/surgical objectives of such a program. Currently, 3-D imaging is used in skeletal and facial reconstruction, angiography, and endoscopy to communicate complex interrelationships to physicians for planning purposes. Interactive image-guided therapy for minimally invasive surgical procedures demands more than the usual precision and is presently on the horizon. Herein, we present cases that illustrate issues of diagnostic dilemmas regarding planning limits of tumor resection, vascular compromise and navigation of endoscopic instruments within body cavities. Because a human being must obey biologic as well as physical principles, issues of contrast agents, respiratory motion, claustrophobia and interfering disease processes must be considered during imaging sequences.
