Motion due to maternal respiration was estimated by extracting a self\u2010gating signal and applying focused navigation. Bulk motion was estimated by splitting the acquisition into sequential bins, reconstructing 3D volumes and applying rigid image registration. These combined motion estimates were used to correct k\u2010space. Self\u2010gating signals were compared to ground truth in simulations and an external sensor in utero. The cumulative position error (CPE) measured the accuracy of motion estimations relative to ground truth in simulations and relative sharpness measured the corresponding impact on image quality for both simulations and in utero data. An expert reviewer performed a blinded ranking of in utero images including uncorrected and corrected data.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Self\u2010gating signals correlated strongly with ground truth for simulations (\n                      <jats:italic>R<\/jats:italic>\n                      \u2009=\u20090.97\u2009\u00b1\u20090.01) and a external sensor for in utero data (\n                      <jats:italic>R<\/jats:italic>\n                      \u2009=\u20090.75\u2009\u00b1\u20090.23). CPE decreased significantly using ACROBATIC (uncorrected: 13.33[12.73\u201314.05], corrected: 2.20[1.80\u20132.61]). Relative image sharpness increased with ACROBATIC for both simulated (4.51[2.89\u20135.79]) and in utero data (1.12[0.77\u20131.44]) consistent with expert ranking where ACROBATIC images were given the best rank in the majority of cases.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>ACROBATIC enables motion correction in 3D radial fetal MRI.
