In the creation of interesting radiological cases in a digital teaching file, it is necessary to adjust the window and level
settings of an image to effectively display the educational focus. The web-based applet described in this paper presents an
effective solution for real-time window and level adjustments without leaving the picture archiving and communications system
workstation. Optimized images are created, as user-defined parameters are passed between the applet and a servlet on the Health
Insurance Portability and Accountability Act-compliant teaching file server.
