No
The document describes standard image processing techniques (gain/offset correction, defective pixel correction) and does not mention AI, ML, or related concepts.
No.
The device is described as an imaging device intended to capture and display radiographic images, which is diagnostic, not therapeutic.
No
Explanation: The device is an X-ray imager that captures and displays radiographic images. It does not perform analysis or interpretation of these images to provide a diagnosis. Its function is to produce the image itself, which a healthcare professional would then interpret for diagnostic purposes.
No
The device description explicitly states it is a "scintillator-photodetector device (Solid State X-ray Imager)" and describes its physical components and how it converts x-rays into electrical charge. This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is for capturing and displaying radiographic images of human anatomy. This is a diagnostic imaging device, not a device used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.
- Device Description: The description details a scintillator-photodetector device that converts X-rays into digital images. This is consistent with medical imaging equipment, not IVD devices.
- Input Imaging Modality: The input is radiographic images, which are produced by X-ray machines, not from analyzing biological samples.
IVD devices are specifically designed to perform tests on samples taken from the body to provide diagnostic information. This device is designed to create images of the body using external radiation.

Intended Use / Indications for Use
"The device is intended to capture for display radiographic images of human anatomy including both pediatric and adult patients. The device is intended for use in general projections wherever conventional screen-film systems or CR systems may be used. Excluded from the indications for use are mammography, fluoroscopy, and angiography applications".

Device Description
The modified DRX Plus 3543C is a scintillator-photodetector device (Solid State X-ray Imager) utilizing an amorphous silicon flat panel image sensor. The modified detector is redesigned with the intent to reduce weight and increase durability, while utilizing a non-glass substrate material and cesium iodide scintillator. The modified detector, like the predicate is designed to interact with Carestream's DRX-1 System (K090318).
The modified DRX Plus 3543C Detector, like the predicate, creates a digital image from the x-rays incident on the input surface during an x-ray exposure. The flat panel imager absorbs incident x-rays and converts the energy into visible light photons. These light photons are converted into electrical charge and stored in structures called "pixels." The digital value in each pixel of the image is directly related to the intensity of the incident x-ray flux at that particular location on the surface of the detector. Image acquisition software is used to correct the digital image for defective pixels and lines on the detector, perform gain and offset correction and generate sub-sampled preview images.
The modified and predicate are essentially the same as they are both digital x-ray flat panel scintillatorphotodetector devices (Solid State X-ray Imagers) utilizing an amorphous silicon flat panel image sensor. The predicate and modified are both DRX Plus 3543 flat panel detectors, the difference is that the modified device utilizes a cesium iodide (Csi) scintillator, whereas the predicate utilizes gadolinium oxysulfide (GOS). The modified device official product name is marketed as "Lux 35 Detector." Both flat panels operate primarily in a wireless state, using a battery for power and allows wireless communication for control and data transmission. This eliminates the need for cables that can hinder efficient workflow. The detectors have the ability to communicate via a wired ("tethered") connection to the console, if desired.

Technological Characteristics
The modified detector is substantially equivalent to the predicate device currently cleared on the market (K150766) and uses the same fundamental scientific technology as the predicate device. The detectors are both digital x-ray flat panel scintillator-photodetector devices (Solid State X-ray Imager) utilizing an amorphous silicon flat panel image sensor. The predicate and modified are both DRX Plus 3543 flat panel detectors, the main difference is that the modified device utilizes a cesium iodide (Csi) scintillator and non-glass substrate whereas the predicate utilizes gadolinium oxysulfide (GOS) and a glass substrate. The modified device official product name is marketed as Lux 35 Detector.
Both flat panels operate primarily in a wireless state, using a battery for power and allows wireless communication for control and data transmission. This eliminates the need for cables that can hinder efficient workflow. The detectors have the ability to communicate via a wired ("tethered") connection to the console, if desired. The modified detector is designed to interact with Carestream's existing acquisition software that resides on the legally marketed Carestream DRX-1 System (K090318). The predicate device (DRX Plus 3543) has clearance with DRX-1 under K150766. Additionally, the DRX-1 System has clearance for the following Carestream detectors:

Carestream has obtained previous detector clearances for use with DRX-1, as listed above. This submission is for the clearance of the modified digital flat panel detector only.
After images are captured with the digital flat panel detector and can be communicated to the DRX-1 System console. The DRX-1 System contains Image Eclipse Processing Software II to allow rendering of the images. The image is processed and transformed into data for viewing and then put into DICOM format for output. Image Eclipse Processing Software II has been cleared for use (K180809) with previous Carestream DRX Plus 2530C under K183425.
The image acquisition software corrects the digital image for defective pixels and lines on the detector. perform gain and offset correction, and generate sub-sampled preview images. The image acquisition software that resides on the DRX-1 System console will be replaced with Image View Software. The ImageView Software has obtained several FDA clearances for use with Carestream Digital Radiography Systems used with the Carestream flat panels:
- 트 K163203 - DRX Evolution System with Image View Software

Summary of Non-Clinical Testing
Clinical testing was not required to establish substantial equivalence. Bench testing was sufficient to assess the device safety and effectiveness. The performance of the modified device DRX Plus 3543C (Lux 35) detector was evaluated in non-clinical (bench) testing using a Phantom Image Study. A technical analysis (non-diagnostic) of image quality attributes such as detail, sharpness, noise and appearance of artifacts were compared for each image.
Greater than 84% of all responses were rated 0 or higher in favor of the modified DRX Plus 3543C panel. All ratings for the attributes (detail contrast, sharpness and noise) were significantly greater than 0 indicating that the modified DRX Plus 3543C images were equivalent to just noticeably better than the predicate images.
