6 Evaluation of a surface imaging system to perform deep inspiration breath-hold technique for external beam radiation therapy of left-sided breast cancer

Abstract

Introduction. Deep inspiration breath-hold (DIBH) technique is used to reduce cardiac doses of left-sided breast radiation therapy. We studied the accuracy and time saving of using a 3-dimensional surface imaging technique with the AlignRT system (VisionRT) to perform DIBH instead of our usually used spirometry-based system.
