An approach to the creation of multimedia textbooks for radiology instruction.

We developed a standardized approach for creating computerized multimedia textbooks based on four principles: (1) multimedia textbooks should resemble printed books, (2) the creation of multimedia textbooks should be relatively inexpensive, (3) multimedia textbooks should be completely digital, and (4) the construction of multimedia textbooks should be simple. To facilitate this approach, an inexpensive, user-friendly multimedia authoring tool called The Annotator was used. The Annotator, a Hypercard-based program that runs on any Macintosh computer, helps authors rapidly create sophisticated radiologic multimedia textbooks. This program provides a textbooklike shell that can be filled with digitized media (video clips, audio clips, images, and text). This approach, which is applicable to any multimedia hardware platform, allows the authorship of multimedia textbooks that can be easily transported to any future multimedia platform.
