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

CareView 1500Cw is a kind of wireless portable digital X-ray flat panel detectors which have 434mm×355mm imaging area. The device communicates by not only the wireless communication but also wired communication feature (Giga-bit Ethernet communication mode by connecting the power box) optionally.

The device intercepts X-ray photons and then the scintillator emits visible spectrum photons that illuminate an array of photo detectors (a-Si) that create electrical signals. After the electrical signals are generated, it is converted to a digital value and an image will be displayed on the monitor.

The detector should be integrated with an operating PC and an X-ray generator to utilize as digitalizing X-ray images and transfer for radiography diagnostic.

The detector can't provide feedback to the generator to terminate the x-ray exposure.

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

The CareView 1500Cw detector is indicated for digital imaging solution designed for providing general radiographic diagnosis of human anatomy. It is intended to replace radiographic film/screen systems in all general-purpose diagnostic procedures. This product is not intended for mammography applications.
