Implementation of triggered kilovoltage imaging for stereotactic radiotherapy of the spine for patients with spinal fixation hardware

ABSTRACT: Highlights • Triggered imaging is an effective method of assessing intrafraction motion for stereotactic spine patients with hardware.• The technology provides the ability to detect intrafraction motion exceeding 1 mm so treatment can be paused and reassessed.• In our cohort, the average intrafraction motion was 0.35 mm with 1 of 33 fractions exceeding the 1 mm motion tolerance.

Background and purpose

Mitigation of intrafraction motion (IM) is valuable in stereotactic radiotherapy (SRT) radiotherapy where submillimeter accuracy is desired. The purpose of this study was to investigate the application of triggered kilovoltage (kV) imaging for spine SRT patients with hardware by correlating kV imaging with patient motion and summarizing implications of tolerance for IM based on calcu
