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 independent one-dimensional margins for single-fraction frameless stereotactic radiosurgery brain cases using CBCT
Qinghui Zhang, Maria Chan, Chandra Burman +2
Setting a proper margin is crucial for not only delivering the required radiation dose to a target volume, but also reducing the unnecessary radiation to the adjacent organs at ris…
Feasibility Study of Real-Time Planning for Stereotactic Radiosurgery
Qinghui Zhang, Yulin Song, Maria Chan +2
Purpose: 3D rotational setup errors in radiotherapy are often ignored by most clinics due to inability to correct or simulate them accurately and efficiently. There are two types o…
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…
