GE HealthCare (GEHC) has received U.S. Food and Drug Administration (FDA) clearance for its 3-tesla MRI scanner Signa Magnus for head imaging.
The system is specifically tailored for neuroimaging and features an asymmetrical, head-only gradient coil design, which achieves higher gradient performance due to its reduced inner diameter, GEHC said. The asymmetrical design shifts the gradient isocenter to the patient edge of the coil rather than its geometric center, enabling patient head access and avoiding shoulder width constraints.
The head-only design allows the scanner to deliver a gradient amplitude and slew rate greater than conventional 60 cm or 70 cm bore whole-body MRI systems, the company noted.
