Abstract
Abstract: The monitoring of patients position during treatment in radiotherapy requires suitable real-time visualization tools which provide a maximum of information. Often, only Electronic Portal Images (EPIs), which are of poor quality, exist for the dynamical verification of position deviations, whereas static image material of higher quality is available from diagnostics and treatment planning. A framework for the fusion of static and dynamic multimodal image data is proposed, which is based on the several image sources existing in radiotherapy.
