Accuracy and precision of patient positioning for pelvic MR-only radiation therapy using digitally reconstructed radiographs.

Conclusions
 The MRCAT pseudo-CT method provides clinically acceptable accuracy and precision for patient positioning for pelvic radiation therapy based on planar DRR images. Furthermore, due to the reduction of geometric uncertainty, compared to dual-modality workflow, the approach is likely to improve the total geometric accuracy of pelvic radiation therapy.
