iMRI Neurosurgery Solution

NORAS offers 1.5T and 3T eight-channel head coils for imaging in the neurosurgical OR environment.

The two-part construction of the OR Head Coil allows the removal of both coil sections during the preparation phase as well as during the intervention. This enables easy patient positioning and excellent access to the FOI (field of interest). While attached, the two coil halves form an eight-channel volume array with very good field homogeneity and image quality.

The OR Head Holder ensures the secure immobilization of the patient’s head during the surgical intervention. Furthermore, the OR Head Holder serves as fixation of both coil halves.
The system design ensures a sterile “chamber“ between two OR drapes. Hence, none of the cables nor any of the coils needs to be sterilized.

The OR Head Holder is compatible with the following operating tools:

  • Sugita®
  • Budde® Halo
  • GREENBERG™
  • VarioGuide™ Biopsy Arm
  • LEYLA Flexible Snake Arms

The NORAS OR Head Coil and Head Holder are currently available for Siemens and Philips 1.5T and 3T MR systems. They support the navigation systems of BrainLab and Medtronic.
