Unleash the real power of MR simulation

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.
