The summary describes a standard digital X-ray detector and does not mention any AI or ML capabilities.
No
The device is described as a "Digital X-ray detector" for "general radiographic diagnosis," which is an imaging device used to diagnose conditions, not to treat them.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "indicated for digital imaging solution designed for providing general radiographic diagnosis of human anatomy."
No
The device description explicitly states it is a "wired/wireless flat-panel type digital X-ray detector" and lists multiple hardware components such as SSU, USB Switch Box, cables, and an Access Point. This indicates it is a hardware device, not software-only.
Based on the provided information, the EVS 4343 Digital X-ray detector is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states it's for "digital imaging solution designed for providing general radiographic diagnosis of human anatomy." This involves imaging the human body directly, not analyzing samples taken from the body (which is the core of in vitro diagnostics).
- Device Description: The description details a device that captures X-ray images of the body. It replaces film-based systems for capturing images of the patient.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), reagents, or any processes related to testing samples outside of the body.
In vitro diagnostics are devices used to examine specimens, such as blood, urine, or tissue, that have been taken from the human body to detect diseases, conditions, or infections. The EVS 4343 is an imaging device used to visualize the internal structures of the body directly.

Device Description
The EVS 4343 is a wired/wireless flat-panel type digital X-ray detector that captures projection radiographic images in digital format within seconds, eliminating the need for an entire x-ray film or an image plate as an image capture medium. EVS 4343 differs from traditional X-ray systems in that, instead of exposing a film and chemically processing it to create a hard copy image, a device called a Detector is used to capture the image in electronic form.
EVS 4343 consists of main components such as SSU, USB Switch Box and other accessories (Tether Interface Cable, Access Point, Hand Switch, Generator Interface Cable, LAN Cable, Interface cable, AC Power Code).

10. Summary of Clinical Data
A single-blinded concurrence study according to CDRH's Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging Devices was conducted, and the study confirmed that the new x-ray detectors EVS 4343 provide images of equivalent diagnostic capability to the predicate device, the E-WOO TECHNOLOGY Xmaru1717, and its results demonstrate substantial equivalence.
11. Conclusion [21 CFR 807.92(b) (3)]
The DRTECH EVS 4343 Digital X-ray detector is substantially equivalent to the currently marketed and predicate device (E-WOO TECHNOLOGY Xmaru1717 K091090) in terms of design features, fundamental scientific technology, indications for use, and safety and effectiveness.
Additionally, Substantial equivalence was demonstrated through the non-clinical performance, which complied with the requirements specified in the international and FDArecognized consensus standards, AAMI ANSI ES60601-1, IEC 60601-1-2, ISO 14971, IEC 6220-1 and NEMA PS 3.1 - 3.20 and the clinical test, which complied with the requirements specified in the CDRH's Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging Devices.
The results of these tests demonstrate that DRTECH EVS 4343 Digital X-ray detector meets the acceptance criteria and is adequate for this intended use. The comparison of technological characteristics, non-clinical performance data, safety testing, and clinical image concurrence data demonstrates that the device is as effective, and performs as well or better than the predicate devices.
