In this review article, we discuss various technical aspects of image-guided respiration-gated radiation therapy. We first review some basic concepts related to respiratory gating, including gating window, duty cycle, residual motion, internal/external gating, amplitude/phase gating, etc. We then discuss 2 implementations of image-guided respiration-gated treatment, i.e., the Mitsubishi/Hokkaido technique for internal gating and the MGH technique for external gating. Several existing problems related to respiratory gating, namely external gating mode (phase vs. amplitude), imaging dose for internal gating, gated treatment for lung cancer without implanted fiducial makers, as well as gated intensity-modulated radiation therapy issues, are also discussed along with potential solutions.
