## Indications for use
Multimodality Simulation Workspace (MM Sim) is a 3D and 4D image visualization, multi-modality manipulation and contouring tool that helps the preparation of treatments such as those performed with radiation (for example, Brachytherapy, Particle Therapy, External Beam Radiation Therapy). It provides tools to view existing contours, create, edit, modify, copy contours of regions of the body, such as but not limited to, skin outline, targets and organs-at-risk. It also provides functionalities to create simple geometric treatment plans. Contours, images and treatment plans can subsequently be exported to a Treatment Planning System.
