GE Revolution HD

Description

Overview

The GE Revolution HD brings together the core innovations of GE Healthcare’s flagship CT technology into a high-performance scanner. Built on GE’s Gemstone™ detector architecture—a garnet-based scintillator that recovers 4 times faster with 100 times primary speed over conventional materials—the system sets a high benchmark for low-contrast detectability, spatial resolution, and artifact reduction.

Featuring Gemstone Spectral Imaging (GSI), the Revolution HD switches rapidly between 80 kVp and 140 kVp in 0.25 milliseconds during a single rotation. This provides quantitative dual-energy tissue characterization, enabling clinicians to assess tissue composition, map iodine distribution, perform virtual non-contrast (VNC) conversions, and differentiate renal stone types.

Key Features & Advanced Technologies

• Gemstone™ Detector & Volara™ DAS: Manufactured from synthetic garnet, this detector features ultra-fast primary decay and minimal afterglow. Combined with the Volara™ Data Acquisition System (delivering 2.5x more views per rotation), it renders micro-structures down to 0.23 mm spatial resolution.

• Gemstone Spectral Imaging (GSI): Ultra-fast single-source fast kV-switching captures registered dual-energy data across a full 50 cm Field of View (FOV). Generates monochromatic energy images (40–140 keV) and material-density pairs (Iodine/Water, Calcium/Water) to improve lesion detection.

• ASiR-V™ & Veo™ Iterative Reconstruction: Next-generation iterative reconstruction algorithms reduce image noise by up to 91% and patient radiation exposure by up to 82% compared to standard filtered back projection (FBP).

• SnapShot™ Freeze Technology: Intelligent motion-correction software that compensates for coronary vessel motion, enhancing spatial resolution up to 6x and yielding an effective temporal resolution of 29 ms.

• Smart MAR (Metal Artifact Reduction): Isolates photon starvation and beam-hardening streaks caused by orthopedic joint replacements, dental work, or vascular coils to reveal hidden soft tissue detail.

• Volume Helical Shuttle / Volume Shuttle: Enables dynamic 4D volume acquisitions extending coverage up to 8 cm for brain perfusion and up to 31.2 cm for dynamic 4D CTA.
