Circle Cardiovascular Imaging vs Hyperfine Swoop
Hyperfine sells a scanner, a 0.064T portable brain MRI with Optive AI reconstruction. Circle sells software for CT, CTA and MR studies. Swoop goes to a neuro ICU or a resource-limited hospital without a shielded room. StrokeSENS suits a stroke center that wants ASPECTS and LVO calls on CT, holding K250221 for ASPECTS (product code POK) and K212261 for LVO (product code QAS, filed by Circle Neurovascular Imaging). The bedside MRI buyer and the stroke-center CT buyer differ, though a stroke center with a neuro ICU could buy both.
Swoop images T1, T2, T2-FLAIR and DWI. A Malawi implementation paper lists lower resolution, longer scans and no contrast-enhanced T1. openFDA shows 17 Hyperfine records, the newest Swoop K262622 on August 19, 2026. The FY2025 10-K describes ownership plus an annual software, service and support agreement after a one-year warranty, on 36- or 60-month terms. An older Scientific Reports paper estimated about $50,000 per system (currency not stated). Circle publishes no price or license terms. Hyperfine's own preliminary Q3 2026 release puts revenue up 55% year over year, and a Yahoo Finance summary shows a Q2 2026 net loss of $9.3M (currency not stated).
