Abstract: QuickTime virtual reality (QTVR) is a software technology that creates, on a normal computer screen, the illusion of holding and turning a three-dimensional object. QTVR is a practical photo-realistic virtual reality technology that is easily implemented on any current personal computer or via the Internet with no special hardware requirements. Because of its ability to present dynamic photo-quality images, we reasoned that QTVR can provide a more realistic presentation of anatomic structure than two-dimensional atlas pictures and facilitate study of specimens outside the dissection lab. We created QTVR objects, using portions of the skull, and incorporated them into an instructional program for first-year medical students. To obtain images, the bones of the skull were mounted on a rotating table, and a digital camera was positioned on a swinging arm so that the focal point remained coincident with the rotational center of the object as the camera was panned through a vertical are. Digital images were captured at intervals of 10 degrees rotation of the object (horizontal pan). The camera was then swung through an are with additional horizontal pan sequences taken at 10 degrees intervals of vertical pan. The images were edited to place the object on a solid black background, then assembled into a linear QuickTime movie. The linear movie was processed to yield a QTVR object movie that can he manipulated on vertical and horizontal axes using the mouse. QTVR movies were incorporated into an interactive environment that provided labeling, links to text-based information and self-testing capabilities. This program, Yorick-the VR Skull, has been used in our first-year medical and graduate gross anatomy courses for the past two years. Results of student evaluation of the program indicate that this QTVR-based program is an effective learning tool that is well received by students. (C) 2000 Wiley-Liss, Inc.

Title: Simulation of cardiac excitation patterns in a three-dimensional anatomical heart atlas
Source: COMPUTERS IN BIOLOGY AND MEDICINE 2000, Vol 30, Iss 4, pp 191-205
No. cited references: 26
Abstract: Computerized anatomical atlas systems enable interactive investigation of digital body models. Here we present a three-dimensional atlas of the human heart, based on image data provided in the Visible Human Project. This heart atlas consists of multiple kinds of cardiac tissues and offers unlimited possibilities for its visual exploration. A temporal dimension is added to the underlying heart model by simulation of cardiac excitation spreading. For this purpose a second generation cellular automata algorithm is adapted to the excitation kinetics of cardiac tissue. The presented system is shown as a successful method for the visualization-based Investigation of cardiac excitation. (C) 2000 Elsevier Science Ltd. All rights reserved.

Source: INTERNATIONAL JOURNAL OF NEURORADIOLOGY 1999, Vol 5, Iss 3, pp 271-277
No. cited references: 19
Abstract: Conventional and computer reconstructed angiography can be transformed into pairs of images for stereoscopic viewing. The first paper in this series explains how to produce these images and provides a basic stereoscopic atlas of normal cerebral vascular anatomy. The second paper (see pp. 000-000) presents stereoscopic anatomy on image pairs of the posterior fossa circulation on conventional angiograms.
