Intended Use
The EVS 3643 Digital X-ray detector is indicated for digital imaging solution designed for providing general radiographic diagnosis of human anatomy. This device is intended to replace film or screen based radiographic systems in all general purpose diagnostic procedures. This device is not intended for mammography applications.
Device Description
The EVS 3643 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 3643 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 3643 consists of main components such as SSU. USB Switch Box, Battery Pack, Battery charger and other accessories (Tether Interface Cable, Hand Switch, Generator Interface Cable, LAN Cable, Interface cable, AC Power Code). EVS 3643 should be integrated with an operating PC and an X-Ray generator.
More Information

No
The summary describes a standard digital X-ray detector and its components. There is no mention of AI, ML, or advanced image processing that would suggest the use of such technologies. The performance studies focus on standard radiographic metrics and equivalence to a predicate device.

No
The device is an X-ray detector used for diagnostic imaging, not for treating diseases or conditions.

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 lists multiple hardware components (SSU, USB Switch Box, Battery Pack, Battery charger, cables, etc.) and states it is a wired/wireless flat-panel type digital X-ray detector.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states "digital imaging solution designed for providing general radiographic diagnosis of human anatomy." This describes a device used for capturing images of the internal structure of the body, which is a function of medical imaging, not in vitro diagnostics.
  • Device Description: The description details a "digital X-ray detector" that captures "projection radiographic images." This further reinforces its role in medical imaging.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.) or providing information about a patient's health status based on such analysis, which are the hallmarks of an IVD.

In summary, the EVS 3643 is a medical imaging device used for capturing X-ray images for diagnostic purposes, not an in vitro diagnostic device.

5. Description of the Device [21 CFR 807.92(a) (4)]

The EVS 3643 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 3643 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 3643 consists of main components such as SSU. USB Switch Box, Battery Pack, Battery charger and other accessories (Tether Interface Cable, Hand Switch, Generator Interface Cable, LAN Cable, Interface cable, AC Power Code).

EVS 3643 should be integrated with an operating PC and an X-Ray generator.

6. Intended Use [21 CFR 807.92(a) (5)]

The EVS 3643 Digital X-ray detector is indicated for digital imaging solution designed for providing general radiographic diagnosis of human anatomy. This device is intended to replace film or screen based radiographic systems in all general purpose diagnostic procedures. This device is not intended for mammography applications.

7. Technological Characteristics [21 CFR 807.92(a) (6)]

The EVS 3643 Detector is an indirect conversion device in the form of a square plate in which converts the incoming X-rays into visible light. This visible light is then collected by an optical sensor, which generates an electric charges representation of the spatial distribution of the incoming X-ray quanta.

The charges are converted to a modulated electrical signal thin film transistors. The amplified signal is converted to a voltage signal and is then converted from an analog to digital signal which can be transmitted to a viewed image print out, transmitted to remote viewing or stored as an electronic data file for later viewing.

Comparisons with the predicate, devices show the technological characteristics of the EVS 3643 to be same to the predicate devices. The EVS 3643 is functionally identical to the predicate devices.

8. Substantial Equivalence [21 CFR 807.92(b) (1) and 807.92]

EVS 3643 is a series of the predicate device EVS 4343. The size of the detector, power supply to the detector and the wireless connection are improved.

When compared to the predicate devices (K142475), the EVS 3643 presented in this submission has the same of the followings:

  • Intended Use
  • · Technological characteristics
  • · Design features
  • Communication Method
  • Scintillator Materials

The two devices share the similar performance as the following:

5

  • Performance (MTF)
  • · Performance (DQE)
  • Resolution
  • · Software version

However, the size of the predicate device's detector is 17" X 17" whereas that of EVS 3643 is 14" X 17". Also, the predicate device connects the detector to the SSU through a wire for power supply and data communication whereas the EVS 3643 is also capable of using the battery inside the detector and wireless communication of top of the method the predicate device uses.

Also, there is a change in the version of the software due to the different size of the detector, but there is no change in the function of the software.

In summary, after comparing EVS 3643 and the predicate device, no significant difference was observed. Also, the main comparison items including the intended use and technological characteristics were highly similar or the same. Therefore, EVS 3643 is substantially equivalent to the predicate device.

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 3643 provide images of equivalent diagnostic capability to the predicate devices (K142475) and its results demonstrate substantial equivalence.

Clinical images were provided; these images were not necessary to establish substantial equivalence based on the modifications to the device (note X-ray detector technology that is identical to the predicate device) but they provide further evidence in addition to the laboratory performance data to show that the subject device works as intended.

11. Conclusion [21 CFR 807.92(b) (3)]

The EVS 3643 is substantially equivalent to the currently marketed and predicate devices (K142475) 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 FDA-recognized consensus standards, IEC60601-1, IEC 60601-1-2, IEC62220-1 and IEC 62133 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 EVS 3643 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 safe, as effective, and performs as well the predicate devices.
