The University of Pennsylvania Radiology Department has developed a suite of Web based applications for clinicians and radiologists to provide wide spread, cost-effective and easy access to radiological information. The image Viewer application provides clinicians and radiologists access to all diagnostic reports and digital images performed in the last week for all Emergency Dept. (ED), Intensive Care Unit (ICU) and Neuro/CT studies. Image control options including zoom/pan, rotate, flip, and window/level are all available. The Image Mover/Viewer application gives radiologists and technologists the ability to both move studies between any DICOM Storage Class Provider (SCP) and DICOM Storage Class User (SCU) and to view studies from any DICOM (SCP). All studies viewed with this application automatically transfer through a web server for processing before being displayed. Web server support requires integration using Perl based CGI scripts with. our DICOM/PACS and the MIR/CTN for images and our IDXrad/RIS for reports. Targeted images and reports are automatically routed from the PACS and RIS for storage on the web server, All images sent to the web server are modality specific pre-processed to reduce size and improve contrast. After processing, all images are stored in DICOM and CIF formats. client support requires web browsers with javascript and frame support.

Students seek active learning experiences that can rapidly impart relevant information in the most convenient way possible. Computer-assisted education can now use the resources of the World Wide Web to convey the important characteristics of events as elemental as the physical properties of osmotically active particles in the cell and as complex as the nerve action potential or the integrative behavior of the intact organism. We have designed laboratory exercises that introduce first-year medical students to membrane and action potentials, as well as the more complex example of integrative physiology, using the dynamic properties of computer simulations. Two specific examples are presented. The first presents the physical laws that apply to osmotic, chemical, and electrical gradients, leading to the development of the concept of membrane potentials;this module concludes with the simulation of the ability of the sodium-potassium pump to establish chemical gradients and maintain cell volume. The second module simulates the action potential according to the Hodgkin-Huxley model, illustrating the concepts of threshold, inactivation, refractory period, and accommodation. Students can access these resources during the scheduled laboratories or on their own time via our Web site on the Internet (http://***) by using the World Wide Web protocol. Accurate version control is possible because one valid, but easily edited, copy of the labs exists at the Web site. A common graphical interface is possible through the use of the Hypertext mark-up language. Platform independence is possible through the logical and arithmetic calculations inherent to graphical browsers and the javascript computer language. The initial success of this program indicates that medical education can be very effective both by the use of accurate simulations and by the existence of a universally accessible Internet resource.
