Thanks Marko for your answer. Our procedure is somewhat similar to what you described without the breath hold. We set up the patient with AlignRT, and perform a CBCT prior to each treatment and line up to the biosorb. Usually the chest wall and skin surface line up very well. During the treatment, we gate the beam to ±3mm. The difference is that we don’t do breathhold. I will look into the literature you shared and speak to our physicians about possible DIBH.
