An Apple (Apple, Inc.) 8 core 2.8 GHZ processors with 16 GB of RAM and a NVIDIA (NVIDIA Corp.) Quadro FX 5600 1.5GB stereo 3D dual link DVI (Digital Visual Interface) graphics card utilizing OsiriX software and a Planar (Planar Systems, Inc.) 24 inch stereoscopic monitor was utilized to create the stereoscopic visualization of tumors and normal structures. OsiriX software allows the following manipulation of DICOM (Digital Imaging and Communications in Medicine) radiation therapy data sets. The Anatom‐e(Anatom‐e XRT Information Systems) anatomical reference system was used as a guide in defining anatomical structures. Ten patients with head and neck carcinoma were chosen. Isodose plans generated by the Pinnacle (Koninklijke Philips Electronics) treatment planning system, and the Helical TomoTherapy (TomoTherapy, Inc.) treatment planning system were evaluated in 2D, 3D, and stereoscopic visualization. Three staff radiation oncologists evaluated the treatment plans. The radiation oncologists were asked if their decision making process was changed as the visualization process progressed from 2D, 3D, and stereoscopically.
