Innovative MR-only simulation pelvis lets you plan radiation therapy for male and female pelvic cancer patients with soft-tissue tumors using MRI as a single-modality solution. Within just one MR exam, MR-only simulation provides excellent soft-tissue contrast for target and OAR delineation, and CT-like density information for dose calculations. This not only extends the benefits of MRI’s outstanding soft-tissue contrast to radiotherapy planning, but it also eliminates arduous, error-prone CT-MRI registration from the process, reducing uncertainties and complexity.

Export to treatment planning systems
  • MRCAT images are DICOM conform (CT) for direct export to treatment planning systems
  • 1. Accuracy means: MRCAT provides around 1 mm total geometric accuracy of image data in less than 20 cm Diameter Spherical Volume (DSV). MRCAT provides below 2 mm total geometric accuracy of image data in more than 40 cm Diameter Spherical Volume (DSV)*. * Limited to 32 cm in z-direction in more than 95% of the points within the volume
  • 2. Equivalent means: the simulated dose based on MRCAT images does not differ in 95% of the pelvic cancer patients (Gamma analysis criterion 3%/3mm realized in 99% of voxels within the PTV or exceeding 75% of the maximum dose) when compared with CT-based plan for EBRT.
  • 3. Tested in a non-clinical environment with single Pinnacle user and a 5-beam IMRT plan. Excluding time for optional manual adjustments.
