The hybrid <jats:styled-content style="fixed-case">DIR</jats:styled-content> algorithms in RayStation and <jats:styled-content style="fixed-case">MIM</jats:styled-content> Maestro were evaluated. Contours of the prostate, bladder, rectum, and seminal vesicles (<jats:styled-content style="fixed-case">SV</jats:styled-content>s) were used as region‐of‐interest (<jats:styled-content style="fixed-case">ROI</jats:styled-content>s) to guide image deformation in the hybrid <jats:styled-content style="fixed-case">DIR</jats:styled-content> and to compare the <jats:styled-content style="fixed-case">DIR</jats:styled-content> accuracy. To evaluate robustness of the hybrid <jats:styled-content style="fixed-case">DIR</jats:styled-content> for prostate cancer patients with organs with volume that vary on a daily basis, such as the bladder and rectum, the <jats:styled-content style="fixed-case">DIR</jats:styled-content> algorithms were performed on ten pairs of <jats:styled-content style="fixed-case">CT</jats:styled-content> volumes from ten patients who underwent prostate intensity‐modulated radiation therapy or volumetric modulated arc therapy. In a visual evaluation, <jats:styled-content style="fixed-case">MIM</jats:styled-content> caused unrealistic image deformation in soft tissues, organs, and pelvic bones. The mean dice similarity coefficient (<jats:styled-content style="fixed-case">DSC</jats:styled-content>) ranged from 0.46 to 0.90 for the prostate, bladder, rectum, and <jats:styled-content style="fixed-case">SV</jats:styled-content>s; the <jats:styled-content style="fixed-case">SV</jats:styled-content>s had the lowest <jats:styled-content style="fixed-case">DSC</jats:styled-content>. Target registration error (<jats:styled-content style="fixed-case">TRE</jats:styled-content>) at the centroid of the <jats:styled-content style="fixed-case">ROI</jats:styled-content>s was about 2 mm for the prostate and bladder, and about 6 mm for the rectum and <jats:styled-content style="fixed-case">SV</jats:styled-content>s. RayStation did not cause unrealistic image deformation, and could maintain the shape of pelvic bones in most cases. The mean <jats:styled-content style="fixed-case">DSC</jats:styled-content> and <jats:styled-content style="fixed-case">TRE</jats:styled-content> at the centroid of the <jats:styled-content style="fixed-case">ROI</jats:styled-content>s were about 0.9 and within 5 mm generally. In both software programs, the use of <jats:styled-content style="fixed-case">ROI</jats:styled-content>s to guide image deformation had the possibility to reduce any unrealistic image deformation and might be effective to keep the <jats:styled-content style="fixed-case">DIR</jats:styled-content> physically reasonable.
