The device description explicitly states that the system includes hardware components such as an image receptor, computer, and monitor, in addition to the software.
Based on the provided text, the Varex Nexus DR Digital X-ray Imaging System is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The Varex Nexus DR Digital X-ray Imaging System is an imaging system that uses X-rays to create images of the internal structures of the body. It directly interacts with the patient's body to acquire images, rather than analyzing samples taken from the body.
- Intended Use: The intended use clearly states it's for "general radiographic examinations and applications," which involves imaging the patient directly.
- Device Description: The description details the components (image receptor, computer, monitor, software) and how it converts X-rays into digital signals for imaging, consistent with an in-vivo imaging system.
Therefore, the Varex Nexus DR Digital X-ray Imaging System falls under the category of in-vivo diagnostic imaging devices, not In Vitro Diagnostic devices.

Device Description
The Varex Nexus DR. Digital X-ray Imaging System is a high resolution digital imaging system designed for digital X-ray imaging through the use of an X-ray detector. The Nexus DR. Digital X-ray Imaging System is designed to support general radiographic (excluding fluoroscopy, angiography, and mammography) procedures through a single common imaging platform.
The modified device consists of an X-ray imaging receptor, computer, monitor, and the digital imaging software and the optional Integrated Generator GUI software.
The Varex Nexus DR. Digital X-ray Imaging System is a configurable product platform designed to allow Varex to leverage the common components of digital X-ray imaging systems from which the following medical modalities can be served: General Radiography (excluding fluoroscopy, angiography, and mammography). The Nexus DR. Digital X-ray Imaging System is then configured to function on a computer with modality specific components, functionality and capabilities to complete the specific product package.
Like the predicate device, the modified Nexus DR. Digital X-ray Imaging System is in a class of devices that all use similar technology to acquire digital radiographic images. These devices convert X-rays into visible light that shines onto a TFT array, which converts the visible light into a digital electronic signal. This process is ultimately used for the same purpose as Radiographic film, to create an X-ray image.
Identical to the predicate device, the modified device is capable of interfacing with flat panel detectors in RAD Mode without utilizing an external I/O box to interface with the X-ray generator. The modified device also retains the ability to apply the grid suppression feature.
Similar to the already cleared Nexus DR™ Digital X-ray Imaging System with Stitching and CPI Rad Vision the modified device, Nexus DR™ Digital X-ray Imaging System (with Integrated Generator), has the same intended use for the DR application. The modified device, however, has the ability to allow the operator to control the CPI CMP200 X-ray generator through the Nexus DR™ Graphical User Interface (GUI). All control functions currently available to the operator on the CPI Membrane Rad Console will be available via the Nexus DR GUI. The Nexus DR Digital X-ray Imaging System can then store the images on the local computer, archive them to CD/DVD media, transfer them to Hard Copy format via DICOM printers, or transfer them to PACS reviewing stations in DICOM format.
