A strategy to correct for intrafraction target translation in conformal prostate radiotherapy: Simulation results

A strategy is proposed in which intrafraction internal target translation is corrected for by repositioning the multileaf collimator position aperture to conform to the new target pose in the beam projection, and the beam monitor units are adjusted to account for the change in the geometric relation...
