Motivation: The 64mT Hyperfine Swoop (Hyperfine Inc. Guilford CT) is a first-of-kind point-of-care (POC) commercial system to allow ‘patient-to-scanner’ imaging.
Goal(s): We report an independent technical benchmark analysis of this system’s power consumption in this study (pass-through measures of W, kWh, and A).
Approach: Performance benchmarks of MR systems power consumption was measured per-pulse sequence using consumer-grade instrumentation under continuous monitoring. Custom acquisition protocol using two portable 120VAC NEMA-standard power banks were examined.
Results: A look-up benchmark table of empirical surge current draw (with 120VAC), its implicit advisory, and a potentially viable protocol run example without 'wall' i.e. via stand-alone power supply are reported.
Impact: POC-MR Instrumentation power benchmark considerations on a per-pulse-sequence power consumption basis provide key insights into protocol deployment, scheduling, and optimal scan resource management considerations in resource-limited settings. Successful pulse sequence protocol implementation with under resource-limited setting was also demonstrated.
