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

CareView 1800Cw is a kind of wireless, portable digital X-ray flat panel detectors which have 244 mm x 307 mm 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 1800Cw detector is indicated for digital imaging solution designed for providing general radiographic diagnosis of human anatomy. It is intended to replace radiographicfilm/screen systems in all general-purpose diagnostic procedures.This product is not intended for mammography applications.

## 8. System requirements to operate with other radiographic system components

- 1) Recommended Generator Specification:
Energy range: 40~150kVp

mA range: 10~1000mA(depending on the generator power)

ms range: 10~6300ms to produce 0.1~1000mAs (depending on the generator power)

Note: To our best knowledge, the detector is compatible with the X-ray generators with

thespecifications described above. If you have questions regarding the compatibility issue for othergenerators, please contact your distributor or CareRay.

- 2) ApplicationProgram Interface (API) for system integration manufacturer Peripheral hardware: CareView detector connected via wired communication. CPU: Intel (R) Core (TM) 2 Duo, 2.93GHz or above RAM: 2 GB or higher Hard disk: 160 GB or higher Monitor: 1280 x 1024 or higher OS: Windows XP or Windows 7 Development environment: MS Visual Studio 2005 3) X-ray exposure mode
The synchronous connection mode is the signal transfer modebetween the X-ray generator which sends the X-ray and the detector which receives the X-ray.

CareView 1800Cw supported typical sync mode contains external sync, soft sync, manual sync and auto sync containing FFAED mode.

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

### 9. Substantial Equivalence [21 CFR 807.92(b) (1) and 807.92(b)(2)]

- A Electrical safety and EMC testing
Electrical, mechanical, environmental safety and performance testing according to IEC/ES 60601-1 was performed, and EMC testing was also conducted in accordance with IEC/EN 60601-1-2. All test results are satisfactory.

- A Nonclinical and clinical considerations
The proposed device (CareView 1800Cw) and predicate device (CareView 1500Cw) share most of primary product specifications including intended use, technology, material, and

{8}------------------------------------------------

imaging principle, etc. Difference lies in the mechanical structure. While the predicate detector has a rectangular shape of 355 mm X 434 mm, the subject device is larger and square, measuring 433.5 mm X 433.5 mm. The pixel size stays unchanged from the predicate detector.

The differences of mechanical structure don't affect the technological parameters and clinical images.

#### 10. Conclusion [21 CFR 807.92(b)(3)]

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, the CareView1800Cw X-ray flat panel detector is substantially equivalent to predicate deviceCareView1500Cw (K150929). Both propose and predicate devices are same in the intended use, the design principle, the applicable standards and specification. Some characteristics, for example, the mechanical structure are different. However the test reports in this submission documents provide demonstration that these differences do not raise any new questions of safety an deffectiveness. Therefore, CareRay Digital Medical System Co., Ltd. concludes the CareView1800Cw X-ray flat panel detector is substantially equivalent with the predicate device CareView1500Cw (K150929).
