cardiac anatomy between breath holding and free breathing, CT averaged based targeting could present unique challenges that will merit further analysis and consideration going forward. This work opens interesting opportunities for future cardiac radioablation treatment with smaller target volumes and increased healthy tissue sparing.

Keywords: Cardiac radioablation, gating, ultrasound guidance
