New Hyperfine Swoop® Portable MRI for Easier and Faster Stroke Visualization
Read the press release in Swedish here. Read the press release in German here.
The portable MRI scanner, Hyperfine Swoop®, has received new AI-supported software for better stroke visualization.
Today, Lioness Medtech AB announced the release of a new CE-marked software version for the Hyperfine Swoop® portable MR Imaging® system. The update introduces a new advanced multi-directional diffusion-weighted sequence (Multi-directional DWI).
The enhanced DWI sequence uses a multi-direction image acquisition approach, similar to techniques used in high-field MRI, gives quicker and better visibility into smaller strokes, all done at the patient’s bedside.
Since Hyperfine’s earliest prototype scans in 2016, the image quality of the Hyperfine Swoop® System has improved continuously. Lioness Medtech has been the distributor of the Hyperfine Swoop® system across the Nordics since 2024, witnessing firsthand the evolution of Optive AI™ along with an ongoing series of software, firmware and hardware refinements. Optive AI™ continues to evolve, delivering progressively better image quality over time. This progress is visible directly in side-by-side scan comparisons across software versions, from the earliest images from 2016, to today’s Optive AI™-powered performance.

The imaging processing moves through a multi-stage pipeline: Spanning Sequence Acquisition → Noise Cancellation → Image Generation → AI-driven post-processing; and continues to improve with each software release.
On the hardware side, according to Hyperfine Inc., Swoop model 2 features improvements in the design of the head coil, resulting in increased signal-to-noise ratio at the base of the brain by 20%, expanding the anatomy for which Swoop® delivers diagnostic-quality images.
More importantly, the work-horse sequences, T1, T2, FLAIR, and DWI, including all but FLAIR’s fast acquisition variants, remain available across existing systems, meaning existing users of Swoop® continue to benefit from the platform’s ongoing software improvements.

Note: Sequence specifications are subject to change with future software updates (Model 2 hardware, 10.1 software shown above). Scan time is nominal and can slightly change depending on the acquisition plane (Axi/Cor/Sag). The nominal scan times reported are for axial plane acquisition.
One highlight of the recent software update is that the advanced DWI sequence that delivers enhanced diagnostic image quality by a multi-direction image acquisition approach, similar to high-field MRIs, supporting more confident identification of smaller strokes.*
Swoop®’s user experience is built around a user-friendly tablet-based interface. The entire MR brain scan, from setup through scan preview, is easily accessible and can be performed on an iPad®, allowing operators to view images in real time as the exam progresses. The system integrates securely with hospital IT infrastructure and can receive software updates via remote download, ensuring Swoop® systems can stay up to date with the latest image quality improvements, without requiring on-site visits.

Beyond image quality alone, this evolution reflects a broader shift toward more sustainable, accessible imaging. Swoop® remains significantly more energy- and infrastructure-efficient than conventional high-field MRI: it uses roughly 97% less energy per scan, requires no helium or specialized cooling, and runs on a standard wall outlet, making it deployable at the bedside rather than requiring patient transport to a dedicated MRI enviroment.
| The Swoop® System | High-Field MRI | |
| Energy per Scan | ~675 watt-hours (97% less) | ~19,900 watt-hours |
| Magnet Type | Permanent magnet | Superconducting |
| Magnet Field | 0.064T | 1.5T |
| Power Requirements | Standard wall outlet 120VAC | 480 VAC and high-power electronics |
| Magnet Cooling | No specialized cooling | Complex supercooling: liquid helium and cooling pumps |
| Weight | ~635 kg | ~5990 kg |
| Access | Bedside | Patient transport required |
| Installation | Ship to Customer | Significant infrastructure project |
Hyperfine’s recently announced Model 2 hardware with shortened scan times for existing sequences and improved ease of use for both transport and scanning. As Hyperfine continues to invest in software and hardware innovation, Swoop® is expected to keep advancing, bringing higher image quality, broader clinical utility, and more sustainable imaging to the point of care.
