A three\u2010point thermoplastic head mask with a precut opening and reinforced strips was developed. After molding, it provided sufficient visible facial area as the region of interest for OSI. Using real\u2010time OSI, the head motion of ten volunteers in the new mask was evaluated during mask locking and 15 minutes lying on the treatment couch. Using a nose mark with reference to room lasers, forced head movement in open\u2010face and full\u2010head masks (with a nose hole) was compared. Five patients with claustrophobia were immobilized with open\u2010face masks, set up using OSI and kV, and treated in 121 fractions, in which 61 fractions were monitored during treatment using real\u2010time OSI. With the open\u2010face mask, head motion was found to be and in volunteers during the experiment, and and in patients during treatment. These agree with patient motion calculated from pre\u2010\/post\u2010treatment OSI and kV data using different anatomical landmarks. In volunteers, the head shift induced by mask\u2010locking was and , and the range of forced movements in the open\u2010face and full\u2010head masks were found to be similar. Most (80%) of the volunteers preferred the open\u2010face mask to the full\u2010head mask, while claustrophobic patients could only tolerate the open\u2010face mask. The open\u2010face mask is characterized for its immobilization capability and can immobilize patients sufficiently during radiotherapy. It provides a clinical solution to the immobilization of patients with head and neck (HN) cancer undergoing radiotherapy, and is particularly beneficial for claustrophobic patients. This new open\u2010face mask is readily adopted in radiotherapy clinic as a superior alternative to the standard full\u2010head mask.<\/jats:p>PACS numbers: 87.19.xj, 87.63.L\u2010, 87.59.\u2010e, 87.55.tg, 87.55.\u2010x<\/jats:p>","DOI":"10.1120\/jacmp.v14i5.4400","type":"journal-article","created":{"date-parts":[[2017,2,27]],"date-time":"2017-02-27T23:12:38Z","timestamp":1488237158000},"page":"243-254","source":"Crossref","is-referenced-by-count":61,"title":["Migration from full\u2010head mask to \u201copen\u2010face\u201d mask for immobilization of patients with head and neck cancer"],"prefix":"10.1002","volume":"14","author":[{"given":"Guang","family":"Li","sequence":"first","affiliation":[{"name":"Department of Medical Physics Memorial Sloan\u2010Kettering Cancer Center New York NY USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.
