Device Story

Mobile X-ray system for bedside/portable exams; utilizes digital flat panel detectors (Lux HD 35, Lux HD 43, DRX-LC) with Cesium Iodide scintillators; converts X-rays to visible photons then electron signals via TFT diode capacitor arrays. System includes X-ray generator, tube head, collimator, and touchscreen interface. Features Digital Exposure Control (DEC) for wireless AEC functionality. ImageView software (v2.0) manages image acquisition; Eclipse II software with Smart Noise Cancellation (SNC) processes images to improve contrast-to-noise ratio and preserve detail. Used by clinicians in all patient treatment areas. Output is high-resolution static radiographic image for diagnostic review. SNC enables potential radiation dose reduction without loss of image quality.

Clinical Evidence

Clinical study evaluated SNC image quality using 7 mobile systems at 8 sites with live subjects, anthropomorphic phantoms, and cadaveric specimens. Four board-certified radiologists performed pairwise comparisons of nominal-dose images (no SNC) vs. simulated 50% reduced-dose images (with SNC). Results: SNC images equivalent or superior to non-SNC (p=0.000); mean RadLex score 3.4 (Diagnostic); >99.7% of SNC images rated same or higher than non-SNC. CDRAD phantom testing confirmed similar IQFinv scores at 50% dose reduction. Study supports claim of improved diagnostic quality and potential for dose reduction.

They are intended to replace film/screen systems in all general-purpose diagnostic procedures. Lux HD 35 Detector and Lux HD 43 Detector are not intended for mammography or dental applications. ## DRX-LC Detector DRX-LC, as a major imaging component, are supplied to the manufacturers of medical diagnostic X-ray photography systems and used in conjunction with the medical diagnostic X-ray photography system to image the object to be checked. They are capable of outputting the acquired static images to a processing device after acquisition. ## Device Description The DRX-Revolution Mobile X-ray system will support the new Lux HD Detectors with the DEC function (K243556), additionally the detectors will also support the optional SNC feature (K241505). ## Carestream Mobile X-ray Systems DRX-Revolution Mobile X-Ray System is a mobile diagnostic x-ray system that utilizes digital technology for bedside or portable exams. Key components of the system are the x-ray generator, a tube head assembly (includes the x-ray tube and collimator) that allows for multiple axes of movement, a maneuverable drive system, touchscreen user interface(s) for user input. It is a mobile diagnostic system intended to generate and control X-rays for examination of various anatomical regions. ## Lux HD Detectors (35x43, 43x43 sizes) Lux HD 35x43 and 43x43 detectors are high-definition detectors (100um) designed with a Cesium Iodide scintillator for the conversion from X-ray to visible photon. The visible photons are transformed to electron signals by a diode capacitor array within TFT panel, which are composed and processed by connecting to scanning and readout electronics to form an image by transmitting to the device PC through the user interface. The CsI scintillator provides a high spatial resolution image. The detectors use a glass free technology which makes the overall detector weight lighter and mitigates the risks related to device breakage. Lux HDs are designed with Digital Exposure Control (DEC) functionality which uses a wireless connection to communicate with a DEC control box, which in turn connects to the generator for x-ray control. This DEC feature also enables AEC functions to be used for mobile imaging without a physical wired connection. These detectors will integrate into the DRX-Revolution X-ray system ## DRX-LC Detector DRX-LC digital flat panel detector is a large-sized X-ray flat panel detector with wireless function based on amorphous silicon (a-Si) thin film transistor (TFT) technology. It utilizes a cesium iodide (CsI) {6} scintillator, and a 3064×8696 active pixel matrix with a pixel size of 139μm, providing high-quality radiographic images. The DRX-LC is designed with DEC feature (same as above) using two additional accessories to support DEC function, a wireless control box and wireless transmission adapter. This detector will integrate into the DRX-Revolution X-ray system.

The modifications include the integration of the new Lux HD digital flat panel detectors and inclusion of the SNC and DEC features and are described below. - The cleared Lux HD detectors with Digital Exposure Control (DEC) functionality were cleared in a detector-level submission by Carestream’s development partner under K243556 and then subsequently transferred to Carestream for device listing. Carestream’s version of the detector is the same with the only difference being minor optimization. The DRX-LC was cleared in K230059 for use with general radiography and for use with DEC feature. All of the above detectors with DEC function will be compatible with the mobile system. - The digital radiography systems (DRX-Revolution Mobile X-Ray System) that will support the cleared Lux HD detectors consist of the same fundamental scientific technology and is designed with the same operating principles as the predicate devices. The predicate and modified system consist of the same critical components: an x-ray generator, x-ray tube, collimator, and image acquisition software. The only difference is the minor modification to the acquisition software to support the detectors with DEC functionality. - The ImageView software is the image acquisition software that is installed on the digital x-ray systems. The base version of the software (2.0) has been cleared with the following Carestream DR systems - DRX Evolution Plus (K233381) - DRX Compass (K223842) - DRX-Revolution (K241505) - DRX-Evolution Plus X-ray System, DRX-Compass Mobile X-ray System with Lux HD 35 Detector, Lux HD 43 Detector Detectors (K250954) The image processing software (Eclipse II) includes the optional Smart Noise Cancellation (SNC) module and is the same as the predicate devices. *SNC is not installed on the detectors. It is important to note that the image processing software and the imaging chain remains the same, we are only adding cleared detectors, Lux HD 35, Lux HD 43 (K243556), and DRX-LC for use with the previously cleared Eclipse II w/SNC. Smart Noise Cancellation clearances: - Eclipse II with Enhanced Noise Reduction (K202441) - Eclipse II SNC Claims (K213307) - DRX-Revolution (K241505) - DRX-Evolution Plus (K233381) - DRX-Compass (K223842) - DRX-Evolution Plus X-ray System, DRX-Compass Mobile X-ray System with Lux HD 35 Detector, Lux HD 43 Detector (K250954) {9} Page 6 of 8 # Summary of Clinical Testing A clinical study was designed to evaluate the image quality performance of SNC on images acquired from the Carestream Focus HD 35/43 and Lux HD 35/43 detectors. Performance testing included imaging performance of the Eclipse II (rendering software) with and without Smart Noise Cancellation, capturing images with the Focus HD 35/43 and Lux HD 35/43 detectors for use on mobile and stationary systems. Images were obtained from 7 mobile systems at 8 different sites and acquired using live subjects, anthropomorphic phantoms, and adult cadaveric specimens. All processed images were delivered to a diagnostic workstation with high-resolution monitors for comparative evaluation by board-certified radiologists. The study demonstrated that images processed with SNC are equivalent to or better than images processed without SNC (the predicate device). The following key points summarize the outcomes of the testing for the in-rooms systems: - Overall preference is in favor of SNC at a meaningful level (p = 0.000). - Image quality for SNC is as good as or better than images without SNC (p = 0.000), regardless of image type, with a mean RadLex score of 3.4 ("Diagnostic"), which supports the claim of SNC being safe and effective. Greater than 99.7% of the SNC RadLex images were rated the same as or higher than the non-SNC images. - SNC produces images with hardware appearance as good as or better than the predicate device. - A CDRAD phantom was used to compare images acquired at nominal dose without SNC to images generated at 50% reduced dose with SNC, which produced similar scores of inverse Image Quality Figure (IQFinv). - A reader study conducted by four independent, board-certified diagnostic radiologists compared pairwise live patient images acquired at nominal dose without SNC to simulation-generated images representing approximately 50% dose reduction processed with SNC. Actual live patient images acquired at reduced dose were not obtained or evaluated; therefore, the comparison was limited to simulated reduced-dose images and did not include a direct comparison using real patient images acquired at reduced exposure. The study demonstrated that simulated reduced-dose images processed with SNC were of diagnostic quality comparable to nominal-dose images processed without SNC based on RadLex ratings. The claim below is cleared and applicable to the mobile system. - "SNC provides improved diagnostic quality, preservation of fine detail and better contrast-to-noise ratio for images acquired at clinically nominal exposures. SNC enables customers to lower radiation dose without loss in image quality". *These statements were validated using Carestream CsI detectors in reader studies conducted by board-certified radiologists. Pairwise comparisons were performed between images at nominal exposure dose without SNC and at 50% reduced dose with SNC. The reduced-dose images included live patient images with simulated dose reduction, as well as images of human cadavers and anthropomorphic phantoms obtained using actual reduced-dose X-ray exposures. SNC performance was further confirmed using a CDRAD phantom. IEC EI values on average at nominal and reduced doses were 220 and 110, respectively.* {10} Page 7 of 8 # Summary of Non-Clinical Testing System verification and validation was performed. This testing demonstrates the safety and performance of the new Lux HD detectors integrated with the DRX-Revolution system. Additional IQ testing was performed, which specifically characterizes SNC performance using quantitative methods of analysis of non-clinical data. The "predicate" device processed images without SNC, and the "subject" device processed images with SNC. The predicate and subject devices were evaluated using captures of flat fields and physics phantoms. The images from both devices were quantitatively compared using Normalized Noise Power Spectra (NNPS), standard deviation (noise) of flat sections of the images, Modulation Transfer Function (MTF), and the contrast-detail curve. This testing demonstrated that there is significant noise reduction without impacting sharpness and resulting in retention of image spatial resolution between the predicate and subject devices." # Performance Standards & FDA Guidance Documents The following FDA guidance documents were reviewed prior to the 510(k) submission. - Content of Premarket Submissions for Device Software Functions Guidance for Industry and Food and Drug Administration Staff June 2023 - Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions, June 27, 2025 - Pediatric Information for X-ray Imaging Device Premarket Notifications Guidance for Industry and Food and Drug Administration Staff November 2017 The following performance standards are applicable to the DRX-Revolution Mobile X-ray system: - ISO 14971:2019 Application of risk management to medical devices - ISO 20417:2021 Medical devices - Information to be supplied by the manufacturer - IEC 62366-1:2015+A1:2020 Medical devices - Part 1: Application of usability engineering to medical devices - ISO 15223-1:2021 Medical devices - Symbols to be used with information to be supplied by the manufacturer - Part 1: General requirements - AAMI ES60601-1:2005 +C1;A2: 2012 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601-1:2005 (Third Edition) + CORR. 1:2006 + CORR. 2:2007 + A1:2012) - IEC 60601-1-2:2015 Electro-Magnetic Compatibility including FCC Part 15 Subpart B:2018 - IEC 60601-1-3:2008+A2:2021 (Second Edition) + A1:2013 Medical electrical equipment - Part 1-3: General Requirements for Radiation Protection in Diagnostic X-Ray Equipment - IEC 60601-1-6:2010 + A1:2015, Edition 3.0 Medical electrical equipment - Part 1-6: General requirements for basic safety and essential performance - Collateral standard - IEC 60601-2-54:2009+A1:2015 Particular requirements for the basic safety and essential performance of X-ray equipment for radiography and radioscopy - 60601-2-28:2017 Part 2: Particular requirements for the safety of X-ray source assemblies and X-ray tube assemblies for medical diagnosis - IEC 62304:2006 + A1:2015 Medical device software Software life-cycle processes - ISO 10993-1:2018 Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process {11} - IEC 63000:2018: Technical documentation for the assessment of electrical and electronic products with respect to the restriction of hazardous substances - Digital Imaging and Communication in Medicine (DICOM) Page 8 of 8
