The first assessed patient and radiation therapist (RTT) perspectives on temporary ink skin markings. The second evaluated whether integrating a six\u2010degree\u2010of\u2010freedom (6D) couch could further improve setup accuracy, setup time, IGRT time, and total treatment time when used with marker\u2010less or marker\u2010based workflows.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Questionnaires were completed by 72 breast cancer patients and 29 radiation therapists (RTTs) using a 6\u2010point Likert scale (0\u00a0=\u00a0never to 5\u00a0=\u00a0always). The questionnaire assessed emotional experiences related to temporary skin markings and the level of interest in a marker\u2010less approach. Forty patients were assigned to four setup groups: markers without 6D couch (M), markers with 6D couch (M_6D), marker\u2010less without 6D couch (ML), and marker\u2010less with 6D couch (ML_6D). Setup accuracy, setup time, image\u2010guided radiotherapy (IGRT) time, and total treatment time were compared.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>About 90% of both patients and RTTs preferred a marker\u2010less setup. Marker\u2010less techniques combined with 6D couch achieved comparable positioning accuracy to marker\u2010based methods. Maximum mean setup deviations in the longitudinal axis were 3.3\u00a0\u00b1\u00a01.3\u00a0mm (M), 3.3\u00a0\u00b1\u00a01.5\u00a0mm (M_6D), 2.8\u00a0\u00b1\u00a01.3\u00a0mm (ML), and 3.0\u00a0\u00b1\u00a01.5\u00a0mm (ML_6D). No significant differences were found in setup or IGRT time. Marker\u2010less setups reduced total treatment time by 27.8%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Marker\u2010less setups using SGRT are feasible for breast radiotherapy, providing comparable accuracy and reduced treatment times.
