Spinal Radiosurgery Intrafraction Motion and Dosimetric Impact


Nzhde Agazaryan, professor of Radiation Oncology at the University of California Los Angeles discusses intrafraction motion and dosimetric impact in spinal radiosurgery. He opens with a short background on intrafraction movements before delving into the role of intrafraction imaging for minimizing misalignments. He then addresses the dosimetric impact of misalignments. He goes into planning cord constraints as opposed to actual cord tolerances and ends on a planning tool proposal for quantifying dosimetric susceptibility to misalignments.
