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

The CareView 1800Le detector is a class of digital X-ray flat panel detector that has an imaging area of 430mm×430mm. The detector communicates by a wired connection (Giga-bit Ethernet communication mode via connecting the power box).

The detector functions by intercepting X-ray photons. Then the scintillator emits visible spectrum photons that illuminate an array of photo detectors (a-Si) that create electrical signals. The electrical signals are then digitally converted to display an image on the monitor.

The detector should be connected to a computer and X-ray generator to digitize X-ray images and transfer radiography diagnostics. The x-ray generator, an essential part of a full x-ray system, is not part of the subject medical device.

The software that supports the functions of the digital detector CareView 1800Le is unchanged from the predicate.

Generally, CareView 1800Le is the same as the cleared product, CareView 1800L except the

pixel size. The pixel size of CareView 1800Le is 140 μm, while the CareView 1800L is 154 μm.

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

The CareView 1800Le 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.

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

The submitted medical device is the CareView 1800Le digital detector. The other x-ray system components referred below are for information purpose only.

- 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)

{7}------------------------------------------------

Note: To our best knowledge, the detector is compatible with the X-ray generators with the specifications described above. If you have questions regarding the compatibility issue for other generators, please contact your distributor or CareRay.

- 2) Application Program 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: 6 GB or higher

Hard disk: 80 GB or higher

Monitor: 1280 x 1024 or higher

OS: Windows XP or Windows 7 or Windows 10

- Development environment: MS Visual Studio 2005
- 3) X-ray exposure mode

CareView 1800Le 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 1800Le) and predicate device (CareView 1800L) share most of primary product specifications including intended use, technology, material, and imaging principle, power supply method etc. The only difference is the pixel size. While the predicate device pixel size is 154 um, the proposed device pixel size is 140 um. The difference of pixel size doesn'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 CareView 1800Le X-ray flat panel detector is substantially equivalent to predicate device CareView 1800L(K153492).

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

Both propose and predicate devices are same in the intended use, the design principle, the applicable standards and specification. Some characteristics, for example, pixel size is different. However the test reports in this submission documents provide demonstration that this difference doesn't raise any new questions of safety and effectiveness. Therefore, CareRay Digital Medical Technology Co., Ltd. concludes the CareView 1800Le X-ray flat panel detector is substantially equivalent with the predicate device CareView 1800L (K153492).
