GE Signa Ovation Open MRI Scanner

The GE Signa Ovation Open MRI Scanner is designed for patients who have difficulty tolerating the close quarters of conventional MR machines

GE Signa Ovation Overview

The GE Signa Ovation 0.35T MRI system is a state of the art, open MR imaging system designed to provide maximum patient comfort. Its open, patient-friendly design measures 142 cm (41.5 feet) pole to pole with 16 inches of vertical clearance, to accommodate even larger patients without the trauma of closed quarters. Each GE Signa Ovation 0.35T MRI is equipped with a patient table rated to 225 kg (500 lbs) that can swing 25 degrees to either side and laterally an additional 12 cm (5 inches), an integrated transmit/receive body coil and an optional XL body surface coil.
