Hi Jason,
We do SGRT-SBRT with abdominal compression-with respiratory plate and inflatable cuff on a Varian clinac. Most of our plans are Eclipse-VMAT 3 half Arcs and 2 of them with table kicks. We use Align RT for setup and for patient monitoring before and during treatment.
We had a few cases where ART (Align RT) helped us greatly for SBRT patient setup and localization of very large patients, and for patients with shoulder issues where they had to be scanned with arms down. It helped us monitoring the SBRT patient during MD checking the CBCT for tumor localization as much as during the treatment.
