GE HealthCare Revolution EVO
GE HealthCare · Model Revolution EVO
Make low-dose routine. Diagnostic images at the right dose add up to great care. Thats why its essential for you to limit your patients radiation exposure to just whats necessary. To do that, you need a CT that makes it easier for you to lower radiation dose without making it harder to make the right diagnosis. Revolution* EVO delivers several dose-lowering capabilities. Our innovative ASiR-V* iterative reconstruction comes standard, and is designed to reduce noise levels, improve low-contrast detectability and reduce dose by up to 82% in routine imaging for all exams and all patients1,2. Along with ASiR-V, a comprehensive collection of Smart Dose technologies helps you monitor, measure and manage your dose delivery and select the optimum parameters to ensure low dose and diagnostic images. Dose management tools such as CT 4Kids dose-optimized pediatric reference scan protocols, 3D Dose Modulation, Organ Dose Modulation, Dose Check, DoseWatch, DICOM DRSR and more are all at your fingertips. Revolution* EVO is designed to provide the high-resolution, low-dose images and answers that increase your confidenceeven when performing advanced procedures. It helps you stay on top of today's standard of care. Improving spatial resolution by up to 100% over previous GE CT scanners enables the image clarity you need to see fine anatomical details, providing a pathway to a quick, confident diagnosis1. Improved spatial resolution is enabled by the redesigned Clarity Imaging System from the Performix* 40 Plus tube, to the Clarity detector and low-noise data acquisition system inherited from Revolution CT. With the increased weight limit of the Revolution EVO patient table and the improved low-contrast detectability and noise performance of ASiR-V, you can image patients weighing up to 675 lbs. and obtain diagnostic image quality with reduced noise and improved contrast resolution. For pediatric patients, speed and low dose are critical. Fast, up to 175 mm/sec acquisitions enable a reduction in breathing artifacts, and ASiR-V ultra-low-dose capabilities allow you to image pediatric patients confidently. As new clinical and financial models evolve in healthcare, you need a CT that can help you attract new referring physicians, grow the services you offer and the patients you serve. ASiR-V* low-dose capabilities make it ideal for pediatric scans, oncology and chronic disease follow-up. At the same time, Revolution EVO gives you the flexibility to expand your services with Advanced Applications powered by AW. Emergency and vascular. Scan trauma patients quickly and catch arterial phase enhancement easily without sacrificing image quality, with up to 175 mm/sec acquisitions enabled by high-pitch helical IQE and 0.35-second rotation speed. Oncology and chronic disease. Revolution EVO with ASiR-V enables ultra-low-dose imaging so that you can confidently provide a high-level of care to those patients that require multiple scans or frequent follow-up.
Key tips
- ·Never bypass a radiation interlock to "just get the image" - this is one of the few true zero-tolerance rules in BMET work.
- ·Trend image-quality phantom results over time - drift shows up before an outright failure does.
- ·Portable/mobile units take real physical abuse from transport - check wheel locks and cable strain reliefs more often than fixed units.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Image artefacts (rings / streaks / noise)
HighSymptoms: Ring or band artefacts, excessive noise, HU non-uniformity, failed daily air/water calibration.
Root cause: Detector-channel drift or a bad detector module, a DAS fault, or air-cal / tube-output drift.
X-ray tube fault / end of life
HighSymptoms: Tube-arc errors, exposure aborts, kV/mA faults, spits, or noisy bearing; tube pulls high heat units.
Root cause: Anode / bearing wear or vacuum degradation - the CT tube is a wear item.
Gantry rotation / slip-ring fault
MediumSymptoms: Rotation faults, comms errors during rotation, brush dust, drive alarms.
Root cause: Worn slip-ring brushes, a drive-belt / bearing fault, or the data-transmission link.
Table / patient-positioning fault
MediumSymptoms: Table drifts, will not index to the correct position, height or cradle errors.
Root cause: Table drive, encoder, or brake fault.
Reconstruction / console / network fault
MediumSymptoms: Recon hangs or is slow, images will not send to PACS, console errors.
Root cause: Recon-hardware or console-PC fault, or the network / storage.
Chiller / cooling fault
MediumSymptoms: Over-temperature warnings, exposures inhibited after a series, coolant alarm.
Root cause: Chiller pump / fan, low coolant, or a blocked heat exchanger.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Daily QC per modality: image-quality phantom test
- ·Tube and detector inspection
- ·Annual state-required radiation safety survey
- ·Vendor-scheduled preventive maintenance
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Ring or streak artefacts / failed calibration
- Run the daily air (fast) calibration; if it fails, run the full calibration set.
- Scan a uniform water phantom and review HU uniformity and noise.
- Check the tube warm-up and heat-unit status.
- Escalate a confirmed detector-channel or DAS fault to the OEM.
- Re-verify image quality with the phantom after any correction.
Symptom: Exposure aborts / tube-arc errors
- Note the exact error codes and the phase (warm-up vs scan).
- Run extended tube conditioning / seasoning.
- Review the arc-count and heat-unit trend.
- Confirm chiller operation and coolant level.
- Plan a tube replacement when arc counts climb or output drifts.
