Groups in this outcome
Orthogonal Varian kV OBI Image
Patients are first set up for treatment with surface fiducial marks and followed by an automated image guided alignment procedure to achieve better alignment with the planning image. The automated procedure OBI gives two shifts: vertical and lateral. In the absence of a gold standard, our goal is to compare the vertical and lateral shifts recommended by each pair of automated procedures.
Varian CBCT (Cone Beam CT) Imaging
Patients are first set up for treatment with surface fiducial marks and followed by an automated image guided alignment procedure to achieve better alignment with the planning image. The automated procedure CBCT gives two shifts: vertical and lateral. In the absence of a gold standard, our goal is to compare the vertical and lateral shifts recommended by each pair of automated procedures.
Oblique Brainlab ExacTrac Images
Patients are first set up for treatment with surface fiducial marks and followed by an automated image guided alignment procedure to achieve better alignment with the planning image. The automated procedure ExacTrac gives two shifts: vertical and lateral. In the absence of a gold standard, our goal is to compare the vertical and lateral shifts recommended by each pair of automated procedures.
