[HemoSurf--an interactive hematology atlas on the world wide web]

Microscopic examination of blood films is essential in clinical medicine despite automatic cell counters. To acquire this skill takes time, an adequate technical infrastructure and experienced instructors. In many cases all these things are not readily available. A computer-based learning program such as "HemoSurf" helps to supply these needs. In its learning part, "HemoSurf" allows the user to develop pattern recognition by offering more than 2000 images of blood and bone marrow films. In a stepwise manner the learner is enabled to differentiate leukocytes and recognize qualitative alterations to blood cells. In the reference part the user can look up blood films and some of the corresponding bone marrow films of over 30 diseases. In the World Wide Web "HemoSurf" is accessible via the following URL: [http./(/)www.aum.iawf.unibe.ch/VLZ/ BWL/HemoSurf/Index.htm]. A publication on CD-ROM with different language versions is in preparation.
