Device Story

Stationary X-ray systems (DRX-Evolution Plus, DRX-Compass) utilize X-ray generators, tubes, and flat-panel detectors (Lux HD 35/43) to acquire radiographic images. Detectors convert X-rays to visible light via Cesium Iodide (CsI) scintillator, then to electron signals via TFT array. Systems include ImageView software with Eclipse II image processing and optional Smart Noise Cancellation (SNC) module. Digital Exposure Control (DEC) enables wireless AEC functionality on Evolution Plus. Operated by technologists in clinical settings; images reviewed by radiologists for diagnostic decision-making. Benefits include high-resolution imaging, reduced detector weight via glass-free technology, and potential dose reduction via SNC.

Clinical Evidence

Clinical study evaluated SNC image quality using live subjects, anthropomorphic phantoms, and cadaveric specimens. Four radiologists compared nominal-dose images (no SNC) to simulated 50% reduced-dose images (with SNC). Results: SNC images rated equivalent or better (p=0.000); mean RadLex score 3.4 ('Diagnostic'); >99.7% of SNC images rated same or higher than non-SNC. Non-clinical bench testing (NNPS, MTF, contrast-detail curves) confirmed significant noise reduction without loss of spatial resolution.

Technological Characteristics

Stationary X-ray system; Cesium Iodide (CsI) scintillator; glass-free epoxy laminate substrate; TFT panel design; 100-micron pixel pitch; 16-bit AD conversion. Connectivity: Wireless DEC for AEC. Software: ImageView v2.0 with Eclipse II/SNC. Sterilization: N/A (non-invasive).

Indications for Use

Indicated for general radiographic diagnosis of human anatomy, including adult and pediatric patients. Applicable to skull, spinal column, extremities, chest, and abdomen. Contraindicated for mammography and dental applications.

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.

# Device Description

## Lux HD Digital Flat Panel Detectors (35x43, 43x43 sizes)

Lux HD 35x43 and 43x43 detectors are high-definition detectors (100um) designed with a Cesium Iodide (CsI) 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 which helps to increase the diagnostic confidence. 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 with out-of-bucky exams and mobile imaging without a physical wired connection.

## Carestream In-Room X-ray Systems

The DRX Evolution Plus (K233381), DRX Compass (K223842) are permanently installed diagnostic x-ray systems for general radiographic x-ray imaging. These systems consist of a combination of components including an x-ray generator, workstation computers, various models of patient support tables, wall-mounted image receptors/detectors for upright imaging, various models of tube support devices, x-ray tube, and collimator (beam-limiting device). Currently, the DRX Evolution Plus X-ray system is designed to use a standalone automatic exposure control (AEC) chamber placed in front of the detector to control the x-ray exposures. Lux HD will be compatible with these systems. The DRX-Compass will not support the DEC feature; however the Lux HD detectors can still be used for general radiography.

# Summary of Safety and Performance

## Technological Characteristics

The modified DRX-Evolution Plus (K233381), DRX-Compass (K223842) systems are substantially equivalent to the predicate devices currently cleared on the market. The below key points support this determination and summarizes the similarities in characteristics when comparing the modified and predicate devices. Any minor differences do not raise questions on performance or safety in regards to the radiographic systems.

- 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 digital radiography systems 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 systems 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
- K233381 (DRX Evolution Plus)
- K223842 (DRX Compass System)

ImagineView 2.0 (B2.2) supports the digital radiography rooms systems (DRX Compass, DRX Evolution Plus) with the Lux HD detectors with DEC, SNC and Smart Virtual LLI features. The Smart Virtual LLI feature is built on top of the existing cleared LLI functionality. It is designed to enhance (not replace) the operator’s workflow by providing an optimized starting point for LLI exams for the technologist. Instead of relying on the existing (cleared) LLI default settings, Smart Virtual LLI intelligently suggests the initial parameter for the regions (top, bottom, collimation width, and OID), allowing for more efficiency in adjustments.

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), Focus HD 35, Focus HD 43 (K213646, K213529) 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 Evolution Plus (K233381)
- DRX Compass (K223842)

## Clinical and Non 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

{9}

and Lux HD 35/43 detectors for use on stationary systems. Images were 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 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 of 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 the images acquired at nominal dose without SNC to the images generated at 50% reduced dose images with SNC which produced similar scores of inverse of 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.

System verification and validation was performed. This testing demonstrates the safety and performance of the new Lux HD detectors integrated with the DRX-Evolution and DRX-Compass systems.

Additional IQ testing was performed, which specifically characterizes the 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 the 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 the subject devices.

In conclusion both clinical and non-clinical (bench) testing demonstrates the DRX Evolution and DRX Compass systems (modified) with integration of the Lux detectors with DEC and SNC is the same as or equivalent to the cleared room systems (predicate) currently on the market.
