It has demonstrated its utility through planning studies for the treatment of multiple metastases. However, the binary collimation approach is idealized in the planning system, while the treatment deliveries must adhere to the physical limitations of the mechanical systems involved [e.g., multi\u2010leaf collimation (MLC) leaf speed]. This work focuses on optimizing the delivery of the binary collimation\u2010based stereotactic radiosurgery\/radiotherapy (SRS\/SRT) plans on a Varian TrueBeam accelerator, considering both dosimetric fidelity and treatment efficiency as variables. A transition window (TW) was defined as the fraction of a control point (CP) during which the requested MLC motion must be completed. The width of TWs was varied between 0% (or step\u2010and\u2010shoot which represents the idealized dose distribution), 20%, 40%, 60%, 80%, and 100%. A variable TW approach was also studied. Delivery accuracy was quantified with gamma analysis (gamma criteria 5%\/2mm) on a PTW Octavius detector. The total beam\u2010on\u2010time was manually recorded. Smaller TWs were associated with more accurate dose deliveries and longer treatment delivery times. The variable TW method was found to be an effective compromise, achieving an average gamma pass rate of 98% and an average delivery time of 9 min.<\/jats:p>","DOI":"10.1002\/mp.17597","type":"journal-article","created":{"date-parts":[[2025,1,8]],"date-time":"2025-01-08T23:23:42Z","timestamp":1736378622000},"page":"1430-1435","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Optimizing the deliverability of binary collimation\u2010based SRS treatment for multiple metastases with multiple prescriptions"],"prefix":"10.1002","volume":"52","author":[{"given":"Eva","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Physics and Atmospheric Science Dalhousie University  Halifax Nova Scotia Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christopher G.","family":"Thomas","sequence":"additional","affiliation":[{"name":"Department of Physics and Atmospheric Science Dalhousie University  Halifax Nova Scotia Canada"},{"name":"Department of Medical Physics, Nova Scotia Health Queen Elizabeth II Health Sciences Centre  Halifax Nova Scotia Canada"},{"name":"Department of Radiation Oncology Dalhousie University  Halifax Nova Scotia Canada"},{"name":"Department of Radiology Dalhousie University  Halifax Nova Scotia Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alasdair","family":"Syme","sequence":"additional","affiliation":[{"name":"Department of Physics and Atmospheric Science Dalhousie University  Halifax Nova Scotia Canada"},{"name":"Department of Medical Physics, Nova Scotia Health Queen Elizabeth II Health Sciences Centre  Halifax Nova Scotia Canada"},{"name":"Department of Radiation Oncology Dalhousie University  Halifax Nova Scotia Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R.
