Revolution HD 128 High-Definition Imaging Performance

The Revolution HD combines a high-resolution Gemstone detector, rapid gantry rotation, and 128-slice reconstruction. These technologies work together to provide detailed anatomical imaging for routine examinations and demanding specialty applications.

Gemstone Detector for Fine Anatomical Detail

The Revolution HD uses GE’s Gemstone detector technology to capture detailed imaging information across 40 mm (1.57 in) of anatomy per gantry rotation.

Its fast detector response helps preserve X-ray measurements while limiting interference from earlier signals.

The system can achieve spatial resolution as fine as 0.23 mm (0.009 in), allowing clinicians to evaluate small anatomical features that may be difficult to distinguish in lower-resolution images.

This level of detail supports imaging of coronary arteries, fine bone structures, blood vessels, and other anatomy where small differences can affect clinical interpretation.

128-Slice Reconstruction from 64-Channel Acquisition

The GE Revolution HD 128 uses 64-channel acquisition with overlapping reconstruction to produce up to 128 single-energy image sections per rotation.

Overlapping reconstruction creates additional, closely spaced image sections from the original scan data. This provides more positions through which clinicians can review anatomy without requiring a second examination.

The detector captures 40 mm (1.57 in) of anatomical coverage per rotation. The 128-slice designation describes reconstructed image output rather than 128 independent detector rows.

These capabilities support detailed multiplanar and three-dimensional review of anatomical structures.

0.35-Second Rotation for Fast CT Acquisition

The Revolution HD completes a gantry rotation in as little as 0.35 seconds, helping acquire anatomical information over a shorter period and limiting the effects of patient movement.

This is particularly useful for cardiac imaging, where coronary arteries move continuously, and for selected vascular examinations requiring precise contrast timing.

The scanner also supports efficient routine head, chest, abdominal, pelvic, and emergency CT examinations.

Volara Data Acquisition for High-Resolution Images

GE’s Volara technology processes the X-ray measurements collected by the Gemstone detector.

Its high-density sampling helps preserve fine anatomical information during image reconstruction and reduce certain image distortions.

This supports detailed evaluation of small bone structures, soft tissues, and blood vessels.

Revolution HD 128 Image Reconstruction & Dose Management

The Revolution HD supports different reconstruction and exposure-control technologies that help facilities maintain diagnostic image detail while managing radiation dose. Each addresses a different part of the imaging process, from reducing image noise to adapting exposure settings to the patient.

Iterative Reconstruction for Image Clarity & Dose Management

Image reconstruction converts measurements collected during CT scanning into images clinicians can interpret. GE offers several reconstruction methods that help reduce unwanted graininess, known as image noise.

- ASiR: Adaptive Statistical Iterative Reconstruction reduces image noise while preserving diagnostically useful detail. This can support appropriately selected lower-dose examinations.
- ASiR-V: An advanced iterative reconstruction method that further improves noise reduction and image clarity during compatible examinations.
- Veo: Uses model-based iterative reconstruction, which mathematically accounts for how CT images are formed to improve fine detail and the visibility of tissues with subtle differences in contrast.

Available reconstruction technologies depend on the system’s software generation and installed configuration. ASiR and ASiR-V provide iterative reconstruction options, while Veo offers additional model-based reconstruction capabilities on equipped systems.

Actual image-quality and dose benefits depend on patient anatomy, examination requirements, and scanning protocols.

Patient-Specific Radiation-Dose Controls

Compatible Revolution HD configurations include technologies that help technologists select and adjust X-ray exposure according to the patient and examination.

- SmartmA: Automatically varies X-ray tube current according to patient anatomy, helping match radiation output to differences in body size and thickness.
- kV Assist: Helps select an appropriate X-ray tube voltage, which affects how X-rays penetrate different tissues and influences image quality and radiation exposure.
- Organ Dose Modulation: Adjusts exposure during selected examinations to help manage radiation reaching sensitive anatomical regions.
- Pediatric Scanning Protocols: Provide examination settings suited to smaller patients and their particular imaging requirements.

These functions support patient-specific dose management without removing the need for appropriate clinical protocols and technologist oversight.

Smart MAR for Clearer Imaging Around Metal

Metal implants can produce streaks and distortions in CT images, making nearby tissues difficult to evaluate.

Available Smart Metal Artifact Reduction (Smart MAR) reduces these distortions during image reconstruction, improving visibility around joint replacements, surgical hardware, and other metallic implants.

This can be particularly valuable for orthopedic assessment, postoperative imaging, and examinations where metal interferes with conventional image interpretation.

Smart MAR requires compatible installed software.

Revolution HD 128 Patient Access & Positioning

The Revolution HD combines a 70 cm gantry opening with motorized patient positioning and available high-capacity table configurations. These features help facilities accommodate different patient sizes and clinical requirements while supporting consistent examination preparation.

70 cm Gantry for Patient Access

The Revolution HD features a 70 cm (27.6 in) gantry opening for routine head-to-body imaging.

Its gantry supports tilt adjustments of up to 30 degrees in either direction, allowing technologists to adjust the scanning angle for selected head examinations and other positioning requirements.

Front and rear gantry controls, patient alignment features, and compatible in-room operating functions help technologists prepare examinations efficiently.

Patient Table Capacity & Available Travel

The Revolution HD offers patient-table configurations designed for different patient sizes and examination requirements.

Documented configurations include:

- 500 lb (227 kg) Patient Capacity: Supports a broad range of patients during routine and advanced diagnostic examinations.

MXR Imaging helps facilities select patient-table configurations and positioning accessories suited to their clinical needs.

Revolution HD 128 Exam Planning & Workflow Automation

The Revolution HD supports examination-preparation tools designed to reduce repetitive setup steps, improve positioning consistency, and streamline clinical workflows.

One Step Positioning & Gantry Controls

Compatible workflow technologies include:

- One Step Positioning: Moves the patient table toward a predefined scanning position with fewer manual adjustments, helping streamline patient preparation.
- Xtream Gantry Display: Provides patient and examination information at the scanner, with available patient-facing educational content to help explain the procedure.
- One Stop ED: Supports emergency examination setup through compatible gantry-mounted controls, allowing technologists to manage selected patient and scanning functions near the table.

These functions address different parts of examination preparation and can reduce repetitive tasks during busy clinical workflows.

Their availability depends on the installed hardware and software configuration.

Dynamic Transition for Contrast Scan Timing

Contrast-enhanced CT uses injected contrast material to make blood vessels and certain tissues easier to see.

Available Dynamic Transition technology helps coordinate image acquisition with the arrival of contrast in the selected anatomical region.

This supports consistent timing during vascular and other contrast-enhanced examinations where capturing the appropriate enhancement phase is important.

Automated Image Processing & PACS Connectivity

The Revolution HD supports automated image reconstruction, examination management, and transfer to compatible picture archiving and communication systems (PACS).

PACS allows medical images to be stored, retrieved, and reviewed across a healthcare facility. The scanner exchanges images using Digital Imaging and Communications in Medicine (DICOM), the standard used to connect compatible imaging systems.

These capabilities help completed examinations move efficiently from acquisition to clinical review.

Available network services and automated functions depend on the installed console and software.

Revolution HD 128 Advanced Clinical Imaging

The Revolution HD supports specialized imaging technologies that provide additional information beyond conventional anatomical CT. Available options extend the platform’s capabilities in cardiac imaging, tissue characterization, vascular assessment, and neurological examinations.

Gemstone Spectral Imaging for Tissue Characterization

Gemstone Spectral Imaging (GSI) is one of the Revolution HD platform’s most distinctive advanced capabilities.

Optional GSI rapidly switches between two X-ray energy settings during scanning. Because different materials absorb X-rays differently at different energy levels, the resulting information can help clinicians distinguish tissues and materials that appear similar in conventional CT images.

Compatible applications include:

- Kidney Stone Characterization: Helps distinguish certain stone compositions by analyzing differences in X-ray absorption.
- Material Separation: Provides additional information about substances such as iodine and water within the imaged anatomy.
- Virtual Noncontrast Imaging: Uses spectral data to create images that estimate the appearance of anatomy without contrast material.
- Lesion Evaluation: Provides additional tissue-characterization information for selected oncology and abdominal examinations.

GSI can also support specialized vascular examinations and other clinical applications.

Compatible configurations can reconstruct up to 256 spectral image sections per rotation. GSI requires the appropriate acquisition hardware, software, and licenses.

SnapShot Freeze for Clearer Cardiac CT

Coronary arteries move continuously during the cardiac cycle, making detailed cardiac imaging challenging.

Optional SnapShot Freeze technology analyzes coronary vessel movement and reduces motion-related blurring during image reconstruction.

This helps improve visualization of coronary anatomy during selected cardiac CT angiography examinations.

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

The technology can be particularly useful when coronary movement would otherwise limit image clarity.

Volume Shuttle for Brain Perfusion Imaging

Available Volume Shuttle technology extends imaging coverage during repeated CT acquisitions by moving the patient table between scanning positions.

This allows the scanner to collect data across a larger anatomical region than the detector covers in one rotation.

With compatible perfusion software, these repeated acquisitions can help assess how blood moves through brain tissue over time, supporting selected neurological and vascular evaluations.

The supported coverage and available examinations depend on installed acquisition and reconstruction software.

Advanced Vascular & 3D Image Review

Compatible advanced visualization applications allow clinicians to evaluate acquired CT data from multiple perspectives.

Available functions may include:

- Advanced Vessel Analysis: Supports additional views and measurements of blood vessel anatomy.
- 3D Volume Visualization: Creates anatomical images that can be rotated to help evaluate complex fractures, vascular structures, and surgical anatomy.
