From: Reproducibility of deep inspiration breath hold for prone left-sided whole breast irradiation
During simulation, one prone shallow breathing (SB) followed by two prone deep inspiration breath hold (DIBH) CT-scans were taken without altering the scan range. The second prone DIBH (DIBH2) CT-scan was acquired with adapted parameters to minimize radiation exposure to the patient. Overlap indices were calculated by rigid registration of DIBH1 and DIBH2.
