IMRIS sterile wireless imaging coil and Monteris laser technologies combine for first time inside a VISIUS Surgical Theatre with iMRI


IMRIS has announced that the company’s InSitu wireless coil and Monteris NeuroBlate laser ablation system have been used together for the first time at a leading United States neuroscience centre. This combination brought improved visualisation and workflow in removing a patient’s low-grade glioma brain tumour inside a VISIUS Surgical Theatre.

“Using the sterile InSitu wireless coil with the NeuroBlate system  streamlines the workflow for transitioning between intraoperative  imaging and surgery and provides high-quality MR images for  navigation,” says Monteris president and chief executive officer John E Schellhorn.




The InSitu Coil is a sterile, wireless, ultra-lightweight and disposable imaging coil that eliminates the need to manage cables and heavy imaging coils typically draped and removed between intraoperative scans. Instead, this coil is secured directly to the sterile field, and provides an open window for direct access to the operative site for the manipulation of the NeuroBlate robotic laser thermotherapy probe or other surgical tools. The NeuroBlate System, a type of laser interstitial thermal therapy (LITT), applies focused energy under MR-guidance to ablate tumours through a minimally invasive approach, while the system’s cooling technology helps avoid damage to adjacent  healthy tissue.




The InSitu wireless coil enhances the image quality of MR images acquired by the VISIUS iMR scanner. The InSitu Coil remains in a consistent position during the procedure, eliminating the small fluctuations in the MR images that may be caused if using a coil that requires repositioning between scans.




“The experience of neurosurgeons has demonstrated that employing MR imaging and software-based visualisation with the Monteris system allows the ablation of targeted tissue using minimally invasive techniques through very small holes in the skull,” Schellhorn adds.
