In order to increase efficiency, an image processing system may create a template identifying volumes of interest to be segmented based on user-specified data relating to a type of treatment and an anatomical site to be treated. The user of the image processing system may create, arrange, view, and manage a patient model including the volumes of interest, reference points, and/or distance measurements based on the arrangement of information using anatomical site rather than using type of imaging modality. The image processing system may segment the identified volumes of interest from image data received from one or more imaging modalities. The image processing system may generate a representation of the patient model including the segmented volumes of interest. The representation of the patient model may be indexed by the volumes of interest.
