We believe this study will greater improve our current knowledge of cervical cancer motion and tumor regression during radiation therapy. There is concern that smaller radiation fields, as would be delivered with IMRT could underdose portions of the tumor resulting in inadequate local tumor control and compromising cure. As a result of this study will be able to infer if IMRT is a safe and reasonable treatment option for patients with intact cervical cancer. Knowledge of the extent and direction of cervical motion will also help determine IMRT treatment margins.
