GE Healthcare has announced that its new Revolution CT system has captured a motion free image of the human heart in just one beat with uncompromised image quality.

GE Healthcare has announced that its new Revolution CT system has captured a motion free image of the human heart in just one beat with uncompromised image quality.

Investigational clinical images to demonstrate the capabilities of the scanner were obtained in collaboration with West Kendall Baptist Hospital.

Baptist Health South Florida radiology chairman and cardiac imaging director Dr Ricardo C Cury served as principal investigator for this study and captured the images.

"Diagnostic quality images are now possible in challenging patients like those with high heart rates, which is a significant advancement," Dr Cury said. "The impressive ability of Revolution to combine coverage, spatial and temporal resolution in a single scanner will translate to many clinical applications and potentially new applications in the future."

"Diagnostic quality images are now possible in challenging patients like those with high heart rates, which is a significant advancement."

The all-in-one Revolution CT system provides uncompromised image quality and clinical capabilities through the convergence of spatial resolution, temporal resolution, coverage, and low dose.

This convergence enables the advanced clinical exams, including comprehensive cardiac exams with anatomic and functional information in just one heartbeat, even with challenging patients and higher heart rates, as well as papid, whole-brain stroke assessment at low dose; and dynamic liver, kidney, or pancreas oncology workup personalised with perfusion and vascular flow analysis.

The key technology enablers of the Revolution CT system include a new 16cm Gemstone clarity detector for whole organ coverage, spatial resolution at 230µ for visualising small anatomy, a new gantry platform that delivers 0.28 seconds rotation speed and tested to support up to 0.2 seconds, and SnapShot Freeze motion correction technology.

The SnapShot Freeze motion correction technology allows the Revolution CT system to deliver 24msec effective temporal resolution for high heart rate imaging without restrictions.

The new device continues GE's commitment to even lower CT doses, with innovations such as the new Gemstone Clarity detector, a dedicated 70kVp scan mode for pediatric use, and ASiR-V, the company's next-generation of iterative reconstruction technology.

The system provides a wider 80cm bore and a quiet scanning experience with the new Whisper Drive system for the patients.

GE Healthcare MICT and AW president and CEO Steve Gray said: "Revolution CT is able to scan even the most challenging patients, day in and day out, with remarkably clear images. And, we made sure that using it is productive, logical, and intuitive."

The CT scanner is yet to receive 510(k) approval from the US Food and Drug Administration. The device is also yet to receive CE Mark approval.
