Swoop Point-of-Care Magnetic Resonance Imaging (POC MRI) Scanner System

The Swoop™ Point-of-Care MRI system provides portable, low-field (0.0686 T) magnetic resonance imaging of the brain for adult and pediatric patients (≥ 6 years) using T1-weighted, T2-weighted, and FLAIR sequences. This iteration introduces updated iterative image reconstruction algorithms, validated through non-clinical testing, aimed at enhancing image quality by reducing noise and artifacts for diagnostic support in settings where conventional MRI is impractical.

The Swoop™ Point-of-Care (POC) Magnetic Resonance Imaging (MRI) System by Hyperfine, Inc. is a portable device engineered to generate images depicting the internal structure of the human head. It is designed for use in scenarios where standard diagnostic brain examinations are not clinically practical or medically prudent, catering to both adult and pediatric patients aged six years and older. The system is intended for deployment at the point-of-care across diverse medical environments, including emergency rooms, critical care units, hospital and rehabilitation rooms, and within emergency transport vehicles, providing diagnostic information when images are interpreted by a trained physician. This MRI system operates using a 0.0686 Tesla permanent magnet and an iterative image reconstruction methodology to produce T1-weighted, T2-weighted, and FLAIR (Fluid-Attenuated Inversion Recovery) sequences of the brain. The device incorporates updated image reconstruction algorithms specifically aimed at improving image quality through the reduction of image noise and artifacts. These enhancements involve replacing a previous non-uniformity field correction method and normalizing image post-processing steps. Performance evaluations were conducted via non-clinical methods, including software verification and validation, phantom-based image quality assessments (including American College of Radiology phantoms), alongside biocompatibility, electrical safety, and electromagnetic compatibility testing.
