GE HealthCare has announced the launch of two pending MR systems — SIGNA Bolt and SIGNA Sprint with Freelium — along with a new AI-powered workflow platform, SIGNA One.

The technologies, unveiled at the annual RSNA meeting underway in Chicago, are currently under FDA review.

The new systems are designed to address efficiency bottlenecks, support sustainability goals, and improve diagnostic consistency, particularly as imaging volumes continue to grow faster than the available radiologist workforce.
SIGNA Bolt is GE’s latest 3T wide bore MR system. It incorporates a high-performance gradient system and a digital RF platform to support both clinical operations and research applications. The scanner is built to reduce operational energy demands while enabling advanced imaging capabilities, including AI-based tools for faster exams and automated workflows. It also supports neurology and oncology care pathways with integrated planning-to-reporting tools.

The 1.5T SIGNA Sprint with Freelium features a sealed, helium-light magnet that uses less than 1% of the helium found in conventional MR systems. Its ventless design enables flexible installation, even in nontraditional or remote care environments.

GE says the Sprint system aims to balance sustainability with high image quality, supported by deep learning applications such as AIR Recon DL and Sonic DL. It also includes two layers of operational automation, scanning autonomy and autoramping, to reduce the need for technician oversight and minimize system downtime.

Both systems run on SIGNA One, a new AI-driven MR workflow platform. The software is designed to streamline patient setup, positioning, and scanning through a simplified user interface, real-time guidance, and contactless physiological monitoring. GE is leveraging NVIDIA GPUs to power SIGNA One’s deep learning tools and image reconstruction capabilities.

“The urgency for greater access, efficiency and precision in MRI has never been greater,” said Kelly Londy, president and CEO of MR at GE HealthCare. “With the introduction of our advanced SIGNA lineup, we’re delivering on a bold vision for MRI.”
