PURPOSE: A film-based teaching file takes up space and the need to search through such a file places limitson the extent to which it is likely to be used. Furthermore it is not easy for doctors in a medium-sized hospitalto experience a variety of cases, and so for these reasons we created an easy-to-use digital imaging teaching filewith HTML(Hypertext Markup Language) and downloaded images via World Wide Web(WWW) services on the Internet. This was suitable for use by computer novices. MATERIALS AND METHODS: We used WWW Internet services as a resource for various images and three different IMB-PC compatible computers(386DX, 486DX-II, and Pentium) in downloading theimages and in developing a digitalized teaching file. These computers were connected with the Internet through ahigh speed dial-up modem(28.8Kbps) and to navigate the Internet. Twinsock and Netscape were used. HWP 3.0, Korean word processing software, was used to create HTML(Hypertext Markup Language) files and the downloaded images were linked to the HTML files. In this way, a digital imaging teaching file program was created. RESULTS: Access to aWeb service via the Internet required a high speed computer(at least 486DX II with 8MB RAM) for comfortabel use ;this also ensured that the quality of downloaded images was not degraded during downloading and that these were good enough to use as a teaching file. The time needed to retrieve the text and related images depends on the sizeof the file, the speed of the network, and the network traffic at the time of connection. For computer novices, adigital image teaching file using HTML is easy to use. CONCLUSION: Our method of creating a digital imaging teaching file by using Internet and HTML would be easy to create and radiologists with little computer experience who want to study various digital radiologic imaging cases would find it easy to use.
