Intended Use

Vantage Galan 3T systems are indicated for use as a diagnostic imaging modality that produces cross-sectional transaxial, coronal, sagittal, and oblique images that display anatomic structures of the head or body. Additionally, this system is capable of non-contrast enhanced imaging, such as MRA.

Technology

The Vantage Galan MRT-3020 is a 3 Tesla MRI system that uses a new in-house magnet and gradient coil, a new Real-time Platform architecture for stable and high-speed processing by the Real Time Manager. It includes advanced software applications such as AI-supported 4D Flow visualization for blood flow analysis, Zoom DWI for smaller field-of-view diffusion imaging to reduce artifacts, and 3D-QALAS for quantitative T1, T2, and PD mapping using an interleaved Look-Locker sequence with T2 prep and IR pulses. The AiCE Reconstruction Processing Unit utilizes AI methods to improve MRI image reconstruction.

Performance

Performance testing included bench tests and volunteer imaging for the 4D Flow, Zoom DWI, and 3D-QALAS sequences. Clinical image quality was evaluated by expert reviewers comparing contrast and signal strength against published reference images. Risk management and software verification/validation were conducted following FDA guidance. Testing demonstrated the device meets predetermined acceptance criteria and is safe and effective for its intended use.
