“…Even physiological processes can be applied to such models, e.g., the contraction of reconstructed muscles (Garner and Pandy, 2001; Casebeer et al, 2002). The ability of today's powerful computers to render views of any structure in real time (Guttman, 2000; Evesque et al, 2002; Gerlach and Hersch, 2002; Dornan et al, 2003) should be used in anatomy courses as an addition to cadaver dissection (Marks, 2000). Real and virtual‐reality learning can be supplemented with Web‐based anatomy atlases for the benefit of clinicians, educators, and researchers (Brinkley et al, 1997).…”

The new media have become widely used tools in medical instruction today. But are they regarded as useful by students training to become medical doctors? What are students' most important criteria for a good CD-ROM or valuable Internet resources? To answer these questions, and to obtain definite data on the use of new media, we distributed a questionnaire to preclinical medical and dental students of the Johannes Gutenberg University in Mainz, Germany. The evaluation of 397 questionnaires demonstrates that 94.9% of the students use personal computers; 91.6% of the 85.8% who own a computer have access to the Internet. The Internet is used at least once a week by 70.1% of students for private and by 59.9% for study purposes. Offers of course-relevant material (Workshop Anatomy for the Internet) are of major interest. CD-ROMs with anatomy applications are used by 58.9% of the students. The subjective effectiveness regarding various aspects of learning using books versus CD-ROMs is compared and the students' views of the importance of different features of electronic media are outlined, including course-relevant high-resolution and quality material, key word search, state-of-the-art information, and clearly laid-out tables. The findings of this survey demonstrate high student demand for computer-aided instruction and anatomy applications offered on the Internet and on CD-ROMs. The students' main focus of interest was found to be examination-relevant material and supplemental study material for courses offered locally. The present results may serve as a basis for the development of valuable educational aids.

Parallel unfolding and visualization of curved surfaces extracted from large three-dimensional volumes

Abstract. Although many three-dimensional (3D) medical imaging visualization methods exist, 3D volume slicing remains the most commonly used technique for visualizing medical data from modalities such as CT, MRI, and PET. We propose to extend the possibilities of oblique slicing to developable curved surfaces that can be flattened and displayed in two dimensions without deformation. Such surfaces can be used to follow curved anatomical structures while preserving distance metrics at visualization time. They may also be useful for the staging of tumors, i.e., to evaluate the spatial extension of a tumor. We propose an out of core algorithm that runs in parallel on a multi-PC architecture and is able to extract surfaces from very large 3D datasets such as the visible human data set (man: 13 GB, woman: 49 GB). Experimental performance results are presented which demonstrate that parallel surface extraction is scalable and has a reasonable overhead compared with traditional oblique planar slicing. Surface extraction is made available to the public as one of the services offered by EPFLs visible human web server (http://visiblehuman.epfl.ch).
