Treatment planning is done to deliver 7000 cGy to 8750 cGy to the maximum using Xknife-4 software supplied by Radionics. The treatment field arrangement for our LINAC-based treatment contains 13 arcs spaced at 15° intervals for approximately 1300 total degrees of arc rotation (Fig. The CT data set is required for planning by the Radionics software, and we use the CT image set to delineate the external contour, the eyes, optic nerves, and brain stem. The MR image sets are transformed into the BRW coordinate system using the fiducials on the MR images. The target volumes are drawn using the MR image sets obtained with the Radionics universal localizer (UCLF) in place during the MR scans and using the Siemens MR head coil. target is determined using the sagittal and axial MR scans.
