Rotation Effects on the Target-Volume Margin Determination
Qinghui Zhang, Weijun Xiong, M. Chan +2
Rotational setup errors are usually neglected in most clinical centers. An analytical formula is developed to determine the extra margin between clinical target volume (CTV) and pl…

Three Dimensional Expansion of Margins for Single-fraction Treatments: Stereotactic Radiosurgery Brain Cases
Qinghui Zhang, Maria Chan, Yulin Song +1
Purpose: To derive a clinically-practical margin formula between clinical target volume (CTV) and planning target volume (PTV) for single-fraction stereotactic radiosurgery (SRS).M…
