Yes
The "Intended Use / Indications for Use" states that the device is "indicated for use in generating radiographic images of human anatomy for diagnostic X-ray procedures."
No
The device description clearly states it is a "wireless, lightweight, cassette-sized, flat panel X-ray detector" and details its physical components like the amorphous silicon flat panel, scintillator, electronics, and enclosure. While it uses software (XISL) to control the detector, the core device is a piece of hardware.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "generating radiographic images of human anatomy for diagnostic X-ray procedures." This involves imaging the internal structure of the body using X-rays.
- Device Description: The description details a flat panel X-ray detector that captures X-ray images.
- Input Imaging Modality: The input is explicitly stated as "X-ray."
- Anatomical Site: The anatomical site is "Human anatomy," referring to the body itself.
IVD devices, as defined by regulatory bodies, are used to examine specimens (like blood, urine, tissue) taken from the human body to provide information about a physiological or pathological state. This device does not interact with or analyze such specimens. It is a component of an X-ray imaging system used to visualize the body directly.

Device Description
The XRpad2 4343 HWC-M is a wireless, lightweight, cassette-sized, flat panel X-ray detector for digital radiography. It fits into a conventional table or wall-stand Bucky, just like a film-screen cassette. The X-ray detector consists of an amorphous silicon flat panel with a directly deposited Csl:Tl scintillator and dedicated read-out, scan, and control electronics, all packaged in a carbon-fiber and aluminum enclosure. The outside dimensions of the detector are 460 mm × 460 mm × 15.5 mm, which fits into a standard X-ray cassette Bucky.
The detector can be integrated with an X-ray system to enable digital radiography. The following accessories are available for the XRpad2 4343 HWC-M:
- XRpad LBC-2 (Lithium Battery Charger)
- . XRpad IPU-2 (Interface and Power Unit)
- . XRpad LPT2 Detector Cable
- . XRpad Protective Insert
- AC Cable IEC 60320 C13 DE

- . Trigger Cable 20 m/65.5 ft.
- GigE Interface Cable 7.6 m/25 ft.
- . GigE Interface Cable 15.25 m/50 ft.
Device Software:
The XRpad2 4343 HWC-M device, like the predicate, relies on the X-ray Imaging Software Library (XISL), to control the detector from the host computer. The XISL is a C/C++-coded software library that provides parameterized functions to interface the device to a host work station via an IP Network connection. By use of the application programming interface (API) of XISL one can acquire images and configure all use functions of the XRpad2 4343 HWC-M detector.

Summary of Performance Studies
The proposed new device (XRpad2 4343 HWC-M) and the predicate device (XRpad2 4336 HWC-M) utilize similar technology and materials, are similar in design and construction, and have the same intended use. The construction and physical characteristics of the two devices are similar. The difference is related to a 76 mm increase in the width dimension of the proposed device, which does not impact image quality.
The XRpad2 4343 HWC-M flat panel detector has successfully completed internal non-clinical testing, and complies with IEC and ISO standards and regulations related to medical safety, EMC, and bio-compatibility. A clinical study was not required for the XRpad2 4343 HWC-M device. Taking into consideration the similarities in construction and physical characteristics of the XRpad2 4343 HWC-M to the predicate device, substantial equivalence of imaging performance between the two XRpad2 flat panel detectors can be demonstrated by a comparison of the non-clinical testing results only.
Summary of Non-Clinical Data:
To demonstrate the equivalence of the XRpad2 4343 HWC-M to the predicate device, Varex Imaging has performed internal non-clinical testing and demonstrated compliance with accepted IEC and ISO standards and regulations. In addition, Varex Imaging has followed the non-clinical considerations outlined in the Guidance for the Submission of 510(k)'s for Solid State X-ray Imaging Devices, September, 2016. This testing demonstrated that critical image quality performance attributes, such as MTF and DQE, of the XRpad2 4343 HWC-M are comparable to the predicate device. The resulting data from the conducted non-clinical tests demonstrate substantial equivalence.
