The daily pre\u2010treatment images were reviewed to assess setup variations between each patient and groups for pelvic tilt, pubic symphysis, sacral promontory and the fifth lumbar spine (L5).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Compared with the planning CT, pelvic tilt for most patients was within \u00b12\u00b0 using the BodyFIX and\u2009\u00b1\u20094\u00b0 for the BB. The Butterfly Board had a slightly higher variance both for patient\u2010to\u2010patient (standard deviation of the systematic error) and day\u2010to\u2010day error (standard deviation of the random error). Variance in position between individual patients and the two stabilisation devices were minimal in the anterior\u2013posterior (AP) and superior\u2013inferior (SI) direction for the pubic symphysis, sacral promontory and L5 spine. Re\u2010imaged fractions due to pelvic tilt reduced by about half when BodyFIX was used (39.1% BB, 19.4% BodyFIX). One patient treated with the BB required a re\u2010scan for pelvic tilt. Three patients required a re\u2010scan for body contour variations (two using BodyFIX and one with the BB).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>BodyFIX resulted in a more accurate inter\u2010fraction setup and efficient treatment and is used as the standard stabilisation for gynaecological patients at our centre.
