  title = {{Interactive Visualization of Time-Oriented Treatment Plans and Patient Data}},
  abstract = {This thesis presents methods to support protocol-based care in medicine. Timeoriented treatment plans and patient data are represented visually providing various interaction possibilities to aid execution and analysis of medical therapy plans formulated in the representation language Asbru. We introduce a two-view approach consisting of a Logical View and a Temporal View. The Logical View depicts therapy plans using a flow-chart like representation based on ``clinical algorithms''. The Temporal View on the other hand depicts plans as well as patient data in form of parameters and variables over time. The plan visualization method within the Temporal View is based on the idea of LifeLines. For being able to depict hierarchical structures and temporal uncertainties, we extended this concept and a novel glyph called PlanningLine has been developed. We present a number of existing visualization approaches addressing concepts that can be found in Asbru and discuss their usefulness for our purpose. A user study with eight domain experts (physicians) was conducted at the beginning of this work to acquire requirements and goals for the development. Furthermore, a software prototype has been implemented and evaluated with five domain experts who judged it as usable and easy to understand. The findings of the user study and the evaluation are presented and discussed.
