This high-tech computer software allows the oncologist to combine multiple diagnostic studies for enhanced interpretation of anatomy within regions of interest. The most frequently fused multimodality package is CT (Computed Tomography) and MRI (Magnetic Resonance Imaging). The radiation oncologist uses this specialized tool to create treatments based on the most accurate anatomical information available. The standard procedure of contouring critical structures, areas of interest or tumor volumes are visually enhanced by the fusion.
