First experience with markerless on-line 3D spine position monitoring during SBRT delivery using a conventional LINAC

Spine stereotactic body radiation therapy requires highly accurate patient positioning to reduce toxicity risks to nearby organs-at-risk such as the spinal cord. However, positional verification is often lacking during irradiation. We report our initial experience with markerless on-line 3D spine position monitoring during volumetric modulated arc therapy on a standard LINAC using the gantry-mounted kV imager.
