Revolution HD 64 Acquisition & High-Definition Imaging

The Revolution HD 64 uses a 64-channel acquisition system, GE’s Gemstone detector, and rapid gantry rotation to capture detailed CT images. These technologies support routine diagnostic studies and specialized examinations requiring fine anatomical detail or precise acquisition timing.

64-Slice Acquisition for Detailed Head-to-Body CT

The Revolution HD 64 acquires 64 slices per rotation across 40 mm (1.57 in) of anatomy. With acquired slice thicknesses as thin as 0.625 mm (0.025 in), it supports detailed head, chest, abdominal, pelvic, spine, and musculoskeletal examinations.

During helical scanning, continuous patient-table movement allows coverage of larger anatomical regions. The platform also supports overlapping reconstruction of up to 128 image sections from its 64-channel acquisition data, providing additional closely spaced views without requiring 128 separate physical detector rows.

Gemstone Detector for Fine Anatomical Detail

GE’s Gemstone detector uses fast-response scintillator material to capture X-ray measurements with minimal residual signal between successive readings. Its spatial resolution reaches as fine as 0.23 mm (0.009 in), supporting evaluation of coronary vessels, fine bone anatomy, and other small anatomical structures.

With 40 mm (1.57 in) of detector coverage, the system supports routine head-to-body examinations and compatible advanced acquisition protocols. The detector’s rapid response also enables the fast energy switching used by optional Gemstone Spectral Imaging.

0.35-Second Rotation for Fast CT Acquisition

The Revolution HD completes a gantry rotation in as little as 0.35 seconds, helping limit motion-related image distortion. Fast acquisition is particularly valuable for cardiac imaging, contrast-enhanced vascular examinations, and time-sensitive diagnostic studies.

Volara Data Acquisition for High-Resolution Images

Revolution HD 64 Image Reconstruction & Dose Management

The Revolution HD combines image reconstruction and exposure-control technologies to help facilities balance diagnostic detail with radiation-dose management. Reconstruction software reduces image noise, while automated exposure tools help tailor scanning parameters to the patient and examination.

Iterative Reconstruction for Image Clarity & Dose Management

Iterative reconstruction helps reduce image noise while preserving clinically useful anatomical detail. The Revolution HD platform supports several reconstruction approaches with different performance characteristics.

• • ASiR: Adaptive Statistical Iterative Reconstruction reduces image noise and supports diagnostic image quality at appropriately selected radiation-dose settings. ASiR is a standard Revolution HD reconstruction capability.
  • ASiR-V: Optional advanced iterative reconstruction that offers additional noise reduction and supports dose optimization during compatible examinations.
  • Veo: Optional model-based iterative reconstruction that uses a detailed mathematical model of the CT imaging process to improve fine detail and the visibility of subtle tissue differences.

ASiR-V and Veo require compatible reconstruction hardware, software, and licensing. Actual image-quality and radiation-dose benefits depend on patient anatomy, the clinical task, and the selected imaging protocol.

Patient-Specific Radiation-Dose Controls

The Revolution HD provides automated technologies that help technologists select exposure settings and manage examination protocols.

• • SmartmA: Adjusts X-ray tube current according to changes in patient anatomy and body thickness, helping maintain appropriate image quality throughout an examination.
  • kV Assist: Helps select X-ray tube voltage based on patient characteristics and clinical requirements.

  • CT 4Kids: Provides pediatric scanning protocols designed for the imaging needs of smaller patients.
  • Dose Check: Provides configurable notifications and alerts when planned radiation-dose parameters reach established thresholds.

These technologies complement iterative reconstruction by managing exposure during image acquisition. Available functions and protocol settings depend on the system configuration.

Smart MAR for Clearer Imaging Around Metal

Metal implants can cause streaks and distortions that obscure surrounding anatomy on CT images.

• • Smart Metal Artifact Reduction (Smart MAR): Optional reconstruction technology that reduces artifacts caused by metallic objects, helping improve visibility around joint replacements, surgical hardware, and other implants. This is particularly useful for orthopedic and postoperative examinations.

Smart MAR requires compatible installed software.

Available clinical applications extend the Revolution HD beyond routine CT. Compatible configurations provide additional information about tissue composition, coronary anatomy, cerebral blood flow, and complex vascular structures.

Gemstone Spectral Imaging for Tissue Characterization

Optional Gemstone Spectral Imaging (GSI) rapidly switches between two X-ray energy settings during acquisition. Because different materials absorb these energies differently, GSI can help distinguish tissue and material characteristics that may appear similar on conventional CT images.

Compatible clinical applications include:

Kidney Stone Characterization: Helps distinguish certain stone compositions during urinary tract evaluation.

• • Material Separation: Provides additional information about substances such as iodine and water.
  • Virtual Noncontrast Imaging: Generates images that estimate the appearance of anatomy without contrast material using spectral acquisition data.
  • Lesion Evaluation: Supports selected abdominal and oncology applications by providing additional tissue-characterization information.

GSI can also support specialized vascular imaging and advanced image analysis. It requires compatible acquisition hardware, reconstruction software, and active licenses.

SnapShot Freeze for Cardiac Motion Correction

Coronary artery movement can cause image blurring during cardiac CT, even with rapid gantry rotation.

• • SnapShot Freeze: Optional motion-correction technology that analyzes coronary artery movement during reconstruction to reduce motion-related distortion and improve visibility during compatible cardiac CT angiography examinations.

Under specified cardiac phantom testing conditions, SnapShot Freeze has demonstrated an effective temporal resolution of 29 milliseconds. This describes motion-correction performance rather than the scanner’s physical gantry rotation time.

Volume Shuttle for Brain Perfusion Imaging

Selected neurological examinations require repeated acquisitions to evaluate changes in blood flow through brain tissue.

• • Volume Shuttle: Moves the patient table between acquisition positions during repeated scans, extending anatomical coverage beyond the detector’s 40 mm width. Combined with compatible perfusion software, it supports assessment of blood flow across a larger region of brain tissue.

Available coverage, perfusion measurements, and clinical applications depend on the installed acquisition and reconstruction options.

Advanced Vascular & 3D Image Review

Compatible post-processing applications provide additional ways to analyze CT data and visualize complex anatomical structures.

• • Advanced Vessel Analysis: Creates specialized views and measurements to support evaluation of vascular anatomy.
