Description

The authors report the determination of a strategy of use of different available imagery modalities on the Varian 3 On-Board-Imager (OBI): low energy (kV) and high energy (MV) plane imageries, and volume imagery (Kv-CBCT, cone beam computed tomography). The dose delivered by each device has been quantified on a humanoid phantom with thermoluminescent dosimeters. A prospective clinical compared the three modalities in terms of patient positioning accuracy. It appears that low-energy imagery provides a good reproducibility, a negligible additional dose and a better image quality. Short communication
