Design Considerations for Multi Modality Medical Image Workstations
The introduction of fully digital pictorial information systems in hospitals will result in a number of changes in the clinical work practice. The acceptance of new technologies will decisively depend on the design of medical image workstations. They have to fit into the organization of the diagnostic imaging department, adapt to the attitudes and the behavior of cliniciants and obey psychovisual and ergonomic rules. Technical complexity has to be made completely transparent for the clinical user by appropriate human interface design.
The paper desribes an image workstation approach aiming at these properties. Fundamental conflicts and problems in routine work with images are identified and problem solving strategies and functions are proposed. Most critical functions for convenient image handling and presentation, implemented in an experimental image workstation, are discussed in detail. User interaction principles that avoid the use of keyboards have been introduced that are based on simple rules, easy to understand and consistent for all work procedures. A new touch screen device has been developed for this purpose, combining minimum image degradation and high touch resolution.
