No
The document describes image processing and optimization features (SmartScout) but does not explicitly mention or describe the use of AI or ML algorithms. The performance studies focus on image quality and dose, not AI/ML performance metrics.
No.
The primary stated use of the device is to produce cross-sectional images for diagnostic purposes, aiding in the diagnosis of disease, trauma, or abnormality, and for planning, guiding, and monitoring therapy, rather than directly treating a condition.
Yes
The text explicitly states: "The device output is a valuable medical tool for the diagnosis of disease, trauma, or abnormality and for planning, guiding, and monitoring therapy." This directly indicates its role in diagnosis.
No
The device description explicitly states it is a "multi-slice CT scanner consisting of a gantry, patient table, scanner desktop (operator console), system cabinet, power distribution unit (PDU), and interconnecting cables," which are all hardware components. While it includes software, it is not solely software.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- IVDs analyze biological samples: In Vitro Diagnostics are designed to examine specimens taken from the human body, such as blood, urine, tissue, etc., to provide information about a person's health.
- This device is an imaging system: The description clearly states that this system produces cross-sectional images of the body using X-ray transmission data. It's a medical imaging device, specifically a Computed Tomography (CT) scanner.
- The output is images and analysis of those images: While the device performs analysis on the image data (like spectral imaging for kidney stone characterization), this analysis is based on the physical properties of the tissues and materials within the body as captured by the X-rays, not on the chemical or biological properties of a sample taken from the body.
The device's function is to visualize internal structures and provide information for diagnosis and treatment planning based on those images. This falls under the category of medical imaging devices, not in vitro diagnostics.
N/A
Intended Use / Indications for Use
The system is intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission projection data from the same axial plane taken at different angles. The system has the capability to image whole organs in a single rotation. Whole organs include but are not limited to brain, heart, liver, kidney, pancreas, etc. The system may acquire data using Axial, Cine, Helical, Cardiac, and Gated CT scan techniques from patients of all ages may be obtained either with or without contrast. This device may include signal analysis and display equipment, patient and equipment supports, components and accessories.
This device may include data and image processing to produce images in a variety of trans-axial and reformatted planes. Further, the images can be post processed to produce additional imaging planes or analysis results.
The system is indicated for head, whole body, cardiac, and vascular X-ray Computed Tomography applications.
The device output is a valuable medical tool for the diagnosis of disease, trauma, or abnormality and for planning, guiding, and monitoring therapy.
If the spectral imaging option is included on the system can acquire CT images using different kV levels of the same anatomical region of a patient in a single source. The differences in the energy dependence of the attenuation coefficient of the different materials provide information about the chemical composition of body materials. This approach enables images to be generated at energies selected from the available spectrum to visualize and analyze information about anatomical and pathological structures.
GSI provides information of the chemical composition of renal calculi by calculation and graphical display of the spectrum of effective atomic number. GSI Kidney stone characterization provides additional information to aid in the characterization of uric acid versus nonuric acid stones. It is intended to be used as an adjunct to current standard methods for evaluating stone etiology and composition.

Revolution CT ES and Revolution Apex are multi-slice CT scanner consisting of a gantry, patient table, scanner desktop (operator console), system cabinet, power distribution unit (PDU), and interconnecting cables. The system includes image acquisition hardware, image acquisition and reconstruction software, and associated accessories. The Revolution CT ES has 128 detector rows with 80mm coverage while the Revolution CT and Revolution Apex have 256 detector rows with 160mm detector coverage.
GE has modified the cleared Revolution CT (K163213) within our design controls to include the SmartScout Option to offer optimized thermal management and improved workflow. The SmartScout mode, if selected by the user, allows for performance of tube warmups during patient scout scanning, eliminating user intervention and wait times for tube warmup. It quides the user to the optimal scout scanning parameters, in order to optimize image quality and dose during patient scanning. The user will still have access to the Regular Scout mode where all traditional routine scout technique settings can be accessed and manually prescribed, such as kV, mA, and cradle speed. SmartScout is an added capability and does not remove access to Regular scout mode.

Device Description: Revolution CT Family with SmartScout
The Revolution CT family of products including Revolution CT. Revolution CT ES and Revolution Apex are multi-slice CT scanner consisting of a gantry, patient table, scanner desktop (operator console), system cabinet, power distribution unit (PDU), and interconnecting cables. The system includes image acquisition hardware, image acquisition and reconstruction software, and associated accessories. The Revolution CT ES has 128 detector rows with 80mm coverage while the Revolution CT and Revolution Apex have 256 detector rows with 160mm detector coverage.
GE has modified the cleared Revolution CT (K163213) within our design controls to include the SmartScout Option to offer optimized thermal management and improved workflow. The SmartScout mode, if selected by the user, allows for performance of tube warmups during patient scout scanning, eliminating user intervention and wait times for tube warmup. It quides the user to the optimal scout scanning parameters, in order to optimize image quality and dose during patient scanning. The user will still have access to the Regular Scout mode where all traditional routine scout technique settings can be accessed and manually prescribed, such as kV, mA, and cradle speed. SmartScout is an added capability and does not remove access to Regular scout mode.
Qualitative and quantitative phantom studies demonstrate that the SmartScout delivers the similar CT Scout image quality at the similar size-appropriate dose levels (CTDIvol) compared to reqular Scout scan.
The SmartScout option will be offered on the Revolution Apex system configuration initially and can be ported to Revolution CT and Revolution CT ES in the future.
This modified system has the same intended use and indications for use as its predicate device. The modified system employs the same basic fundamental operating principles as the existing marketed product Revolution CT, and is of comparable type and substantially equivalent to its predicate device.

The letters and the border are both a light blue color. There are three white, teardrop-shaped elements evenly spaced around the outside of the circle.
The SmartScout feature involves hardware and software changes.
The change to implement SmartScout involves minor changes to the source collimator, and corresponding software modifications to manage the new scout scan mode as well as managing the tube thermal conditions, while also meeting a user-selected patient CTDIvol for the scout. SmartScout accomplishes this dual concurrent goal in addition to delivering equivalent performance to Regular scout in terms of sizing of the patient anatomy for the purposes of AEC and diagnostic scan range prescription.
The workflow for SmartScout is designed to be as similar as possible to that of the Reqular scout mode. The need for a tube warmup is dependent upon on the system-specific patient throughput and prior scanning history.

Determination of Substantial Equivalence
The Revolution CT Family with SmartScout option has completed testing and is in compliance with IEC 60601-1 Ed. 3 and its associated collateral and particular standards, 21CFR Subchapter J. and NEMA XR-25, XR-26, XR-28 and XR-29. The proposed device has successfully completed all testing per our quality system as well as comparison testing to the predicate device. It was designed and is manufactured under the Quality System Regulations of 21CFR 820 and ISO 13485. The following quality assurance measures were applied to the development of the system:
- Risk Analysis
- · Required Reviews
- · Design Reviews
- Testing on unit level (Module verification)
- · Integration testing (System verification)
- · Performance testing (Verification)
- · Safety testing (Verification)
- · Simulated use testing (Validation)
GE believes the Revolution CT Family system is of comparable type and substantially equivalent to our currently marketed system Revolution CT (K163213).
The substantial equivalence was also based on software documentation for a "Moderate" level of concern device.
Summary of Additional Testing
In addition to the verification and validation testing successfully completed as required by GE Healthcare's quality system, additional engineering (non-Clinical testing) was performed to provide the requisite data to substantiate performance claims, the revised indications, and ultimately substantial equivalence.
Non-Clinical Testing
The performance evaluation testing used a variety of phantoms representing head and body to provide technical substantiation of the SmartScout performance on the Revolution Apex. Various mathematical and statistical analyses were performed to demonstrate that each performance item was successfully verified and substantiated for data acquisition and optimized image generation. The evaluation also included pediatric phantom evaluation.
Clinical Testing
The Revolution CT family with SmartScout can be fully tested on the engineering bench thus no additional clinical testing was required.
