Orfit MRI-S Solution for brain, head and neck

The Orfit MRI-S Solution for brain, head and neck provides patient immobilization on the Siemens MAGNETOM family of MRI scanners. It allows for fusion of images with the patient in exactly the same position as during simulation and treatment.

The solution includes a High Precision (HP) Base Plate, a Bi-lateral Antenna Holder, a set of six HP Head Supports, and a set of Couch Top Fixations. Patients are immobilized with an Efficast thermoplastic 3-points or 5-points mask. All components and thermoplastic masks are MRI-compatible and meet the standards of Siemens AG Healthcare with respect to functioning on the Magnetic Resonance Systems listed in the table below.

HP base plate

The HP base plate comes with different sets of dedicated indexing fixations so that it can be mounted on top of the different couch tops of the Siemens MAGNETOM family MRI scanners.

Slots are provided in the base plate to attach Orfit Efficast thermoplastic head and neck masks. All Orfit HP Head Supports, Blocks and Wedges can also be positioned on the base plate. This allows the patient to be immobilized in exactly the same position as for simulation and treatment.

Bi-lateral antenna holder

The antenna holder slides over the cranial end of the base plate. It can be opened for easy mounting of the antennas and for patient setup with a mask. In a closed position the antennas are very close to the head of the patient for optimal image quality. The levers of the holder accept the large Flex coils of the Siemens MRI system.
