Hi Ashleigh, we have been using Align RT for our DIBH patients for over a year, and we are awaiting installation of our GateCT in the near future.
We currently use a single camera-based system focussed on the left lateral aspect of the patient. By using the CT lasers and pen marks to mark the height and sup/inf of the breath hold, we ensure that the patient can reproduce the breath hold position prior to scanning, and confirm they relax to the original position on exhalation. Once we are happy with the reproducibility, we mark the lateral laser height along the patients skin to their waistband, so that we can confirm the patient is in the correct breath hold position prior to performing the breath hold scan, which we do immediately following the free breathing scan, instructing them over the intercom.
Hope this helps, Suzanne
