## Intended Use

The Xplorer 1000 is a digital x-ray imager intended as a replacement for x-ray film for general human radiography.

## Device Story

Xplorer 1000 is an optical-based digital x-ray imager; replaces conventional x-ray film. Input: incident x-ray energy. Operation: fluorescent screen converts x-rays to visible light; mirror deflects light; lens focuses light onto high-resolution CCD camera; camera produces digital image. Trigger mechanism captures image upon x-ray beam activation; no connection to x-ray generator required. Used in clinical settings for general radiography. Output: digital radiographic images. Healthcare providers use images for diagnostic assessment of bone and anatomy. Benefits: provides digital imaging capabilities equivalent to film-based systems.

## Clinical Evidence

Clinical study included 20 human subjects undergoing both conventional and Xplorer 1000 radiography across a range of general anatomy. A panel of 3 radiologists evaluated image quality, finding the Xplorer 1000 equivalent to conventional film. Bench testing verified spatial resolution using line pair targets and phantoms, exceeding American College of Radiologists standards.

## Technological Characteristics

Optical-based digital x-ray imager. Components: fluorescent screen, mirror, lens, high-resolution CCD sensor. Energy source: incident x-ray energy. Spatial resolution: 127 microns at 100% MTF. Standalone device; no electrical connection to x-ray generator required.

## Regulatory Identification

A stationary x-ray system is a permanently installed diagnostic system intended to generate and control x-rays for examination of various anatomical regions. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.

## Special Controls

*Classification.* Class II (special controls). A radiographic contrast tray or radiology diagnostic kit intended for use with a stationary x-ray system only is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 892.9.

## Predicate Devices

- IMIX DIGITAL THORAX SYSTEM ([K974863](/device/K974863.md))
- conventional radiographic film (21 CFR 892.1840)

#### Name(s) of the device

| Trade name  | Xplorer 1000 Digital X-ray Imager |
|-------------|-----------------------------------|
| Common name | Digital X-ray Imager              |

Classification name Solid State X-ray Imager

#### Identification of predicate device(s)

Equivalency is based on the IMIX DIGITAL THORAX SYSTEM (K974863) and conventional radiographic film (21 CFR 892.1840).

#### Description of the device

The Xplorer 1000 is an optical based digital x-ray imager. It works by converting incident x-ray energy to visible light by use of fluorescent screen. The visible light is deflected by a mirror to a high resolution CCD camera that produces a digital image. The device trigger mechanism ensures that image is captured when the x-ray beam is turned on. The device does not require any connection to the x-ray generator.

#### Intended Use

The Xplorer 1000 is a digital x-ray imager intended as a replacement for x-ray film for general human radiography.

#### Non-clinical testing

The Xplorer 1000 uses a fluorescent screen of the type used in film / screen radiography to convert x-rays to light. This light is then captured by a high resolution CCD sensor.

To verify the spatial resolution and determine its equivalence to film, tests were performed using line pair resolution targets and radiological phantoms. Resolution was found to exceed the standards set by the American College of Radiologists and, qualitatively, imaging of bone detail, particularly trabeculae, was found equivalent by radiologists.

## Clinical testing

In an image quality study, 20 human subjects were x-rayed both conventionally and with the Xplorer 1000. A range of anatomy was covered representative of general radiography. The results were examined by a panel of 3 radiologists and found equivalent to film.

## Conclusion

Imaging Dynamics concludes that the Xplorer 1000 Digital X-ray Imager is equivalent to the Imix Digital Thorax System (K974863) and conventional radiographic film (21 CFR 892.1840) based upon the following criteria:

- the Xplorer 1000 has the same intended use as the predicate devices; and, .
	- the Xplorer 1000 has radiographic performance equivalent to the predicate devices.
