Description
Inaccuracies in radiation targeting are responsible for incidental exposure of healthy adjacent tissues, causing significant morbidity and mortality. This study focuses on inaccuracies incurred when a tumor is displaced during treatment. To address this problem, the clinical target must be expanded to cover the region through which the tumor might move. The resulting expanded target is known as the Planning Target Volume (PTV). In the current practice, PTV estimation is made without paying attention to off-axis rotation and thus could produce PTV that either miss the true target motion or are larger than needed to cover the target path. This study utilizes tools in classical kinematics to study the effect of off-axis rotation on PTV estimation in comparison with the current practice.
Dates and Times
Start: 3/4/2021 12:00 PM
End: 3/4/2021 1:00 PM
Objectives
1) Recognize the importance of off-axis rotation in modeling motional inaccuracies in radiotherapy;
2) Gain an appreciation for the effect of off-axis rotation on PTV estimation in comparison with the current practice;
3) Introduce classical tools in kinematics to the radiotherapy community.
