- Analysis of Pitch and Yaw Deviations Using an Aid-Pillow for the Head and Neck Cancer on the TomoTherapy
- Abstract
- The aim of this study was to analysis of the pitch and yaw deviations with or without using an aid-pillow for the head and neck cancer on the TomoTherapy. A total of 14 head and neck patients were selected to without-group (n=7) and with-group (n=7). A total of 333 MVCT image sets used to evaluate the translational (lateral, longitudinal and vertical) and rotational adjustments (pitch, roll and yaw) with 153 and 180 MVCT image sets at without- and with-group, respectively. Deviations of without- and with-groups were $0.12^{\circ}$ and $0.09^{\circ}$, respectively at pitch. And, deviations without- and with-groups were $0.47^{\circ}$ and $0.17^{\circ}$, respectively at yaw. In generally, with-group had reduced than without-group for the pitch and yaw deviations. Therefore, using an aid-pillow, it will able to increase the reproducibility of treatment for the head and neck cancer patients on the TomoTherapy.
