Isodose volumes from the prescribed intracavitary brachytherapy will be reconstructed on the megavoltage images. The feasibility of defining the clinical target volume on the megavoltage scans will be explored. This may require fusion with conventional CT images that will already have been taken for diagnostic and external beam treatment planning purposes. Megavoltage and/or fused images will be used to pilot the integration of tomotherapy intensity modulated radiation therapy treatment plans with intracavitary brachytherapy dosimetry.
