Roentgen: radiation therapy and case-based reasoning

Abstract

Roentgen is a case-based aid to radiation therapy planning. It relies on an archive of past therapy cases to suggest plans for new therapy patients. Roentgen supports therapy planning by: (1) retrieving the case which best matches the geometry and treatment constraints of the new patient; (2) tailoring the plan to the specific details of the patient; (3) evaluating the results of applying the plan; and (4) repairing the plan to avoid any discovered faults in treatment results. This final plan is the system's suggestion to the human planner. Roentgen breaks new ground in solving problems in a domain dominated by spatial reasoning and the satisfying of constraints.<>
