Article Title: Migration from full‐head mask to “open‐face” mask for immobilization of patients with head and neck cancer

doi: 10.1120/jacmp.v14i5.4400

Figure Lengend Snippet: Head motion of five claustrophobic patients monitored with AlignRT in real time during treatment, and with both AlignRT and orthogonal kV imaging in pre‐ and post‐treatment (P&P). The average motion of these patients is similar to that of the volunteers. The X‐ray P&P data fall between two sets of AlignRT P&P data (OSI‐1 and OSI‐2) using different reference images. Note: both OSI‐1 and OSI‐2 show P&P differences, quantifying head motion during treatment, although OSI‐1 is more reliable since it does not carry residual head rotation at setup

Article Snippet: A clinical OSI (AlignRT; VisionRT, London, UK) was used in this study.
