: For two equally talented and devote trainees, the efficiency of the training system will dictate the required time for a training. Glass teaching slides are indispensable in residency training. However, its use is inefficient and expensive. The trainees will need to travel to and from the hospital to access a microscope, it takes time to retrieve and file the slides, broken slides and missing slides are common. Although online digital slides are readily available, the speed in view these slides is still significantly slower than using a conventional microscope with the speed of the connection system and the speed of the server as the major hurdles. We designed a hard drive based digital slide system in order to investigate the possibility of using this system to improve efficiency.

Material and Method: In 2012, we started a project in scanning selected slides for educational purpose into whole slide images (WSI) and loaded them into a hard drive. These WSI are then built in to an HTML based program for retrieval and viewing by our trainees. Our program included a function that allowed our trainees to put in their own notes. Survey questionnaire were sent to the trainees to understand their experience. The program is planned to be updated once every year and their opinions were used to improve this program.

Results: This system eliminated the necessity of microscopes and the needed commuting time, the inefficient process of retrieval and filing physical slides, the cost of extra (and often multiple) slides and immunohistochemistry and special stains and other problems associated with glass slides such as missing slides. This system also eliminated the problem of connectivity and slow server response.

Conclusion: This is an ongoing project. The advantage of this design is that it is very versatile and efficient from the user point of view. In particular, this method is very suitable when connectivity is a major issue. However, this system also exposed the problem that the software design and display of the teaching slides can be a rate limiting system of this type of training system.

Biography: Dr. Fung received his medical degree and postgraduate trainings from Taipei Medical University, New York University, the University of Pennsylvania, and the University of Texas M.D. Anderson Cancer Center. He works as a neuropathologist and general surgical pathologist. Dr. Fung is currently the Director of Neuropathology of the Department of Pathology as well as the Director of Histology and Immunohistochemistry Core and Director of Biospecimen Pathology Core of the Stephenson Cancer Center at the University of Oklahoma Health Sciences Center. His major focuses in digital pathology include the use of whole slide image on pathology education and some of his creations can be viewed online at His other focus on digital pathology is the use of whole slide imaging and modern technology in quantitative studies of histologic sections.
