    “…SIMPLE SUMMARY: Deep-inspiration breath-hold (DIBH) techniques are widely used for motion management during CT simulation and treatment delivery, with the underlying assumption of minimal inter-breath-hold variation in organ-at-risk (OAR) geometry. Using a unique dataset from 20 patients, this study presents a novel investigation of the OAR geometric variation between multiple DIBH CT scans in pancreatic cancer stereotactic body radiotherapy (SBRT), and discusses implications for plan accuracy and OAR toxicity. …”
