Using Cross-Sectional Imaging to Convey Organ Relationships: An Integrated Learning Environment for Students of Gross Anatomy

摘要

We have developed a visually oriented, computer-controlled learning environment designed for use by students of gross anatomy. The goals of this module are to reinforce the concepts of organ relationships and topography by using computed axial tomographic (CAT) images accessed from a videodisc integrated with color graphics and to introduce students to cross-sectional radiographic anatomy. We chose to build the program around CAT scan images because they not only provide excellent structural detail but also offer an anatomic orientation (transverse) that complements that used in the dissection laboratory (basically a layer-by-layer, anterior-to-posterior, or coronal approach). Our system, built using a Microsoft Windows-386 based authoring environment which we designed and implemented, integrates text, video images, and graphics into a single screen display. The program allows both user browsing of information, facilitated by hypertext links, and didactic sessions including mini-quizzes for self-assessment.
