Intended Use
VIVIX-S 4386W is indicated for digital imaging solution designed as a general radiographic system for human anatomy. It is intended to replace film or screen based radiographic systems in all general purposes of diagnostic procedures. It is not to be used for mammography. It is intended for both adult and pediatric populations.
Device Description
VIVIX-S 4386W, a flat panel detector model named; FXRD-4386WB with imaging areas of 43cm x 86cm. The device intercepts x-ray photons and the scintillator emits visible spectrum photons that illuminate an array of photo (a-SI)-detectors that create electrical signals. After the electrical signals are generated, it is converted to digital value, and the Software which acquires and processes the data values from the detector. The resulting digital images will be displayed on monitors. These devices should be integrated with an operating PC and an X-Ray generator. It can be utilized to digitalize x-ray images and transfer for radiography diagnostic.
More Information

No
The summary describes a standard digital X-ray detector and associated software for image acquisition and processing, with no mention of AI or ML capabilities.

No.
The device is for diagnostic imaging (replacing film or screen-based radiographic systems for diagnostic procedures) and does not provide therapy.

Yes
The "Intended Use / Indications for Use" section states that the device is intended for "general purposes of diagnostic procedures" and the "Device Description" mentions that it "can be utilized to digitalize x-ray images and transfer for radiography diagnostic."

No

The device description clearly states it is a flat panel detector (FXRD-4386WB) which is a hardware component that intercepts x-ray photons and converts them to electrical signals. While it includes software for data acquisition and processing, it is not solely software.

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

Here's why:

  • Intended Use: The intended use clearly states it's for "digital imaging solution designed as a general radiographic system for human anatomy." This describes an imaging device used to visualize internal structures of the body, not a test performed on samples taken from the body (like blood, urine, or tissue).
  • Device Description: The description details how the device captures X-ray photons and converts them into digital images for display. This is consistent with a medical imaging device, not an IVD.
  • Input Imaging Modality: The input is X-ray, which is a form of radiation used for imaging, not a method for analyzing biological samples.
  • Anatomical Site: It's used for "human anatomy," meaning it images the body itself.
  • No mention of analyzing biological samples: The description and intended use do not mention any process involving the analysis of samples taken from a patient.

IVD devices are specifically designed to perform tests on specimens derived from the human body to provide information for diagnosis, monitoring, or screening. This device's function is to create images of the body.

9. Summary of Non-Clinical Data

A comparison test was conducted between the subject devices (VIVIX-S 4386W) and the predicate device (K181003) on the items such as DQE, MTF and spatial resolution.

These detectors comply with the following international and FDA-recognized consensus standards:

  • 21CFR1020.30, Diagnostic X-ray Systems and their major components
  • . 21CFR1020.31, Radiographic equipment
    • IEC 60601-1 Medical Electrical Equipment -- Part 1: General Requirements for Basic Safety and Essential Performance.
  • . CAN/CSA-C22.2 No. 60601-1 (2008) (Medical Equipment --Part 1 : General Requirements for Basic Safety and Essential Performance) (includes National Differences for Canada)
  • ANSI/AAMI ES60601-1 (2005+ C1:09+A2:10) (Medical Electrical Equipment – Part 1
  • IEC 60601-1-2 Medical Electrical Equipment - Part 1-2 : General Requirements for Basic Safety and Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements And Tests

10. Summary of Clinical Data

A single-blinded concurrence study was conducted, and the study confirmed that the new VIVIX-S 4386W provides images of equivalent diagnostic capability to the predicate devices, the VIVIX-S 1717V and its results demonstrate substantial equivalence.

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

The VIVIX-S 4386W is substantially equivalent to the currently marketed and predicate devices (K181003) 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, 3 and the clinical test.

The results of these tests demonstrate that VIVIX-S 4386W 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.
