Rationale and Objectives. The aim of the study is to show the possibilities opened up by three-dimensional (3D) com-
puter-based models of the human body for education in anatomy, training of radiological and endoscopic examinations,
and simulation of surgical procedures.
Materials and Methods. Based on 3D data sets obtained from the Visible Human and/or clinical cases, virtual body mod-
els are created that provide an integrated spatial and symbolic description of the anatomy by using interactive color/inten-
sity–based segmentation, ray casting visualization with subvoxel resolution, a work for knowledge modeling,
and augmented QuickTime VR (puter, Inc, Cupertino, CA) movies for presentation.
Results. From these models, various radiological, endoscopic, or haptic manifestations of the body can be derived. This is
shown with examples from anatomy teaching, correlation of x-ray images with 3D anatomy for education in radiology,
gastrointestinal endoscopy, correlation of ultrasound images with 3D anatomy in endoscopic ultrasonography, and simula-
tion of drilling in temp
