Online External Beam Radiation Planning and Training

External beam radiation therapy (EBRT) is an effective and widely accepted form of treatment for many types of cancer that requires extensive planning. Unfortunately, current treatment planning systems have limited or no available visual aid that combines patient volumetric models extracted from patient specific CT data with the treatment device in an inclusive 3D interactive simulation. We are presenting new features of a web-enabled system emphasizing several new elements for user interaction and simulation accuracy assessment. We illustrate the potential of 3D simulation in radiation therapy, specifically radiation treatment planning. Embedding patient specific data (CT from DICOM-RT) in a web-based interactive simulation advances the radiation therapy planning by early detection of collision cases. The system may be used to support the decision making process as well as innovations in medical planning and training.
