Description
GE HealthCare Revolution Apex & Revolution CT Technical Reference Manual 5871355-1EN Rev 2 (2023)
The GE HealthCare Revolution Apex & Revolution CT Technical Reference Manual 5871355-1EN Rev 2 (2023) is a detailed technical reference for the Revolution Apex and related Revolution CT configurations identified in the document. It concentrates on safety, quality assurance, radiation dose and image-quality performance, planned maintenance, system specifications, X-ray tube data, CT operating theory, acceptance testing, and radiotherapy treatment-planning requirements. Revision 2 is dated May 2023 and applies to Revolution CT 1.0 software 22MW25.xx for the covered systems.
This is not a general service-repair manual for unrestricted component replacement. The document states that designated service personnel should use the proper service manuals when servicing the system. Its role is different: it provides the technical performance, QA, maintenance-schedule, measurement, acceptance-test, dose, and specification information used to understand and verify scanner performance.

Quality Assurance, Dose and Performance Reference
A major portion of this Revolution Apex technical reference manual is devoted to quality assurance and measurable system performance. The QA chapter includes a testing schedule, 20 cm Water Phantom scans, QA Phantom scans, phantom handling, protocol references, image-analysis reports, representative images, and separate QA data forms for 160 mm and 80 mm systems and for 40 mm systems. The procedures describe positioning and scanning the phantoms, using Image Analysis, checking protocol results, and recording performance data.
The dose and performance material extends beyond routine QA. It covers dose information, stray radiation measurements, deterministic effects, noise, modulation transfer function (MTF), nominal slice thickness, and sensitivity profile. This makes the manual useful when checking whether the scanner is performing within the documented technical framework and when reviewing the parameters that affect radiation output and image quality.
Planned Maintenance and System Technical Data
The planned-maintenance section provides a structured PM schedule for the covered Revolution Apex and Revolution CT systems using the Quantix™ 160 tube. Scheduled items include preliminary PM checks, room-condition inspection, gantry inspection, alignment-light inspection, gantry fans and blowers, scanner desktop and system cabinet PM, UPS battery checks, covers and filters, axial-drive filter cleaning, gantry bearing lubrication, gantry assembly bolt inspection, tube heat-exchanger filter cleaning, detector and DTS PM, PDU checks, table checks, kV/mA/scan-time verification, focal-spot validation and calibration, and image-quality testing.
The system-specification chapters add the electrical and radiation-performance reference data needed around that maintenance work. Topics include compatible certified components, component rating plates, laser alignment lights, main power supply, nominal electric power, CT system X-ray tube ratings, equivalent filtration, half-value layer, kV/mA/exposure-time accuracy, electromagnetic compatibility, and operating, shipping, and short-term storage environmental specifications. A dedicated Quantix™ 160 X-ray tube chapter provides tube model information, operating environment, X-ray characteristics, tube assembly and insert details, environmental health and safety information, markings, and routine maintenance.
CT Operation, Networking and Imaging Functions
The manual also explains CT operating theory and the principal scanner subcomponents, including the X-ray source, detector, gantry, power distribution unit, table, system cabinet, and scanner desktop. It describes how the X-ray source and detector operate and gives configuration information for the detector coverage used by 160 mm, 80 mm, and 40 mm systems.
Network sections document the purpose of connecting the scanner to a network, network-interface technical specifications, information flows, required network characteristics and configuration, compatibility, and hazardous situations that can arise from IT-network failure. Operational-mode coverage includes Scout, Axial, Cine, VolumeShuttle™, Helical, Cardiac Axial, Cardiac Helical, ECG-Modulated mA, SmartTrack, Gemstone Spectral Imaging, and SmartStep. Additional technical topics cover image display, scout-based attenuation characterization, CT perfusion, total scan time, automatic exposure control, slice-thickness reference noise index, SmartmA, Organ Dose Modulation, and Auto Prescription concepts including patient-size estimation and Size Adjusted Noise Index.

Acceptance Testing and Radiotherapy Planning
Revision 2 specifically updates the CT Acceptance Testing chapter to comply with changes in DIN standards. The chapter describes acceptance testing based on IEC 61223-3-5:2019 and includes patient-support positioning, patient-positioning accuracy, preview-image accuracy, tomographic section thickness, dose, noise, mean CT number and uniformity, high-contrast spatial resolution, automatic exposure control, baseline values, constancy-test criteria and frequency, and acceptance testing after a major service action. Test equipment, test procedures, data evaluation, acceptance criteria, and required actions are included where applicable.
The radiotherapy treatment-planning section addresses requirements for providing CT images for RTP. It covers alignment and characteristics of the patient-support top, table sag, integral light markers for patient marking, a typical scan mode for RTP image generation, HU-value conversion, and geometric accuracy of image data. These pages are particularly relevant where CT image geometry and positioning need to be evaluated for treatment-planning workflows.

Taken as a whole, the manual gives trained users and technical personnel a broad reference for scanner safety, performance verification, QA testing, scheduled maintenance checks, dose and image-quality evaluation, equipment specifications, operational theory, network requirements, acceptance testing, and RTP-related image requirements. The coverage is centered on understanding and confirming system performance rather than replacing the separate installation or service manuals referenced by GE HealthCare.
Technical Reference for QA, Performance Checks and Planned Maintenance
Use the GE HealthCare Revolution Apex & Revolution CT Technical Reference Manual 5871355-1EN Rev 2 (2023) when you need the documented procedures and specifications behind QA phantom testing, dose and image-quality checks, planned-maintenance scheduling, CT acceptance tests, system electrical and X-ray data, Quantix™ 160 tube information, or technical operating references for the covered scanners. Having the correct revision helps technicians and qualified users work from the published procedures, performance criteria, safety information, and specifications rather than relying on memory or incomplete notes.
Delivered as an instant PDF after purchase – no shipping delay. Open it on a computer, tablet, or phone and print the pages you need for the job, QA session, maintenance check, or technical reference.
