MRCAT Brain
MR-RT clinical application
MRCAT Brain clinical application allows the use of MRI as the primary imaging modality for radiotherapy planning of primary and metastatic tumors in the brain without the need for CT. Detailed anatomical information for contouring and attenuation maps for dose calculations are both obtained from a single, submillimeter resolution 3D T1W mDIXON MR sequence. Artificial Intelligence (AI) is used for fast computation of continuous Hounsfield units directly on the MR console.

Features
Automatic generation of synthetic CT images using AI
MRCAT Brain uses Artificial Intelligence (AI) for fast computation of MRCAT attenuation maps based on the mDIXON T1W scan. MRCAT generation takes place right on the MR console and provides continuous Hounsfield units for CT-like image appearance.
Seamless workflow integration
DICOM-CT conform, the MRCAT Brain dataset can be exported to treatment planning systems and used as the primary image dataset for dose calculations. You can also use the high-resolution MRCAT data for patient positioning at the Linac. Studies have shown that positioning verification is as accurate as with CT-based workflows***.
