Abstract

3D imaging offers the opportunity to gather new kinds of information for diagnosis and therapy. In order to access this information efficiently we need a model for the integration of knowledge which is extracted from the images. In this paper we present such a model for the description of image information as well as results of image analysis and manipulation. The purpose of the model is its application in computer assisted treatment planning. Therefore, we present a volume representation based on discrete 3D space to map the model on the computer. The representation is an extension of the well-known cell enumeration (CE) representation. We show how to transfer information into this representation and how to access the represented information. We give examples of applications in the planning of radiation therapy, stereotaxy and plastic surgery.
