Novel, Compact, Intraoperative Magnetic Resonance Imaging-guided System for Conventional Neurosurgical Operating Rooms

Intraoperative Imaging Using a Mobile Computed Tomography Scanner

“…The surgery is performed with a distance to the magnet and the operative setting does not need to be changed, for example position of the patient or the surgeon. Other authors report on a compact mobile MR scanner with an integrated navigation system that can be stored under the operating table [12,17,29]. The scanner is draped and can be brought into position if imaging is necessary.…”

Intracranial navigation by using low-field intraoperative magnetic resonance imaging: preliminary experience

“…lished previously. 3,19,37 Briefly, the PoleStar N-10 system is a 0.12-tesla, low-field open MR imager with the 5-G line located 1.5 m from the magnet isocenter. The critical design element of this iMR imager is a pair of parallel, vertically oriented, permanent ceramic magnets that are spaced 25 cm apart.…”

Intracranial Surgery With a Compact, Low-Field-Strength Magnetic Resonance Imager

“…The PoleStar system was conceived by MRI engineers who worked intimately with neurosurgeons to design a system that would interfere as little as possible with surgical routine. 6 This Buser-friendliness[ came at a cost, howeverVa small magnet gap, limited FOV, and variable image quality. 7 The PoleStar N20 was developed to overcome these problems.…”

“…Created by a small startup company, in partnership with Hadani and other neurosurgeons in Tel Aviv, Israel, this device is now marketed by Medtronic Navigation (Louisville, CO). After the initial report of the PoleStar by Hadani et al, 6 other users described their experience. 7Y9 Key features of this system were its mobility within the OR, small footprint, docking underneath a regular operating table, and integrated surgical navigation.…”
