MR-only simulation

MR-only simulation
Compatibility	Ingenia MR-RT 1.5T and 3.0T
Imaging protocol	Dedicated ExamCard provides sequences for: 3D MRCAT source information (mDIXON) Anatomical information for delineation (T2W TSE)
MRCAT generation	Running parallel to image acquisition on the MR console, embedded post-processing generates MRCAT images using: Automated segmentation and tissue classification Automated assignment of CT-based density values
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.
