IMRIS, Inc. announced the granting of three patents by the Japanese patent office related to key technology currently integrated into its intraoperative MRI (iMRI) solution within the VISIUS Surgical Theatre. The patents cover control of effective MR imaging using a movable system; imaging coils where clarity is maintained when used while in position during x-ray use; and other components related to using both MR and x-ray imaging in the same environment. The covered technology is utilized in VISIUS Surgical Theatres which are hybrid operating room suites with iMRI where a diagnostic quality scanner moves to the patient using ceiling-mounted rails.

VISIUS iMRI hybrid ORs may also include x-ray angiography systems where both types of imaging are desired. The fully integrated suites provide neurosurgeons on-demand access to high resolution images - before, during and after procedures without moving the patient from the OR table for truly intraoperative imaging and improved treatment outcomes. During brain tumor procedures, serial scanning gives the surgeon the ability to assess results and perform further resection to remove as much tumor as possible.

Clinical studies indicate a link between more complete removal of some types of tumors and longer life expectancy and quality of life. IMRIS also develops and manufactures proprietary intraoperative CT systems, head fixation devices, imaging coils, and OR tables for use in this unique and multifunctional intraoperative environment.
