Abstract
A system for assisting a user in preparing a brachytherapy pre-implantation plan and post-implantation evaluation for prostate cancer is disclosed. Image scans are loaded into the system. The user places seeds on the various image scans to treat the prostate cancer. The system of the present invention provides for creation of multiple variations to allow a user to compare and contrast plans or evaluations. A user can more easily move between variations of an original plan or evaluation, thereby simplifying the plan and evaluating process. Creation of multiple variations will depend upon altering certain user defined variables.
