Indications for Use
CareView 1800R X-ray Flat Panel Detectors is indicated for digital imaging solution designed for providing general radiographic system in all general purpose diagnostic procedures. CareView 1800R X-ray Flat Panel Detectors is a component of a digital imaging system. Properly integrated into a completed X-ray system, the detector enables the digital X-ray imaging intended for medical application. This product is not intended for mammography applications and dental X-ray applications.
Device Story
CareView 1800R is a stationary X-ray flat panel detector (FPD) component for digital radiography systems. It uses a TFT/PD image sensor with a direct-deposited CsI scintillator to convert X-ray photons into visible light, then into electron signals via a diode capacitor array. The device captures single-frame images, which are processed and transmitted to a PC via a user interface. Used in clinical settings by healthcare professionals, the detector integrates into a completed X-ray system to enable digital imaging. It supports external and manual synchronization modes with X-ray generators. The output is a digital image used by clinicians for diagnostic purposes, facilitating medical decision-making through high-resolution radiographic visualization.
Clinical Evidence
Clinical evidence included a concurrence study of 30 clinical images comparing the CareView 1800R to the predicate device. Results showed no significant difference between the images produced by the subject and predicate devices. Primary evidence for equivalence was based on laboratory performance data (MTF, DQE, NPS, sensitivity, lag, uniformity, etc.) and established scintillator material usage.
Technological Characteristics
Active area 43cm x 43cm; CsI scintillator; TFT readout mechanism; 16-bit ADC; 154µm pixel pitch; 2816x2816 pixel array. Stationary installation. Power consumption ~36W.

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 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: 2 GB or higher
Hard disk: 160 GB or higher

## 9. Substantial Equivalence [21 CFR 807.92(b) (1) and 807.92(b)(2)]
- > 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. Section 201.7.2.7, 201.7.9.1, 201.7.9.2.1.103 and 203.4.1 of IEC 60601-2-54 were also conducted.
- A Nonclinical considerations
The following non-clinical studies have been performed and the results have shown that the CareView 1800R X-ray flat panel detector is substantially equivalent to the predicate devices on the Market (CXDI-40EG).
{7}------------------------------------------------
-Detective quantum efficiency (DQE), Quantum limited performance, Modulation transfer function (MTF), Effects of aliasing, Sensitivity linearity, Lag(Erasure thoroughness), Change in detection sensitivity, Dose requirement and reciprocity changes, Stability of device characteristics with time, Uniformity of device characteristic, Noise power spectrum(NPS), Spatial resolution, Image Acquisition time, & Black level
- A Clinical considerations
A concurrence study of 30 clinical images was conducted to compare the performance of the CareView 1800R to that of the predicate device (K050987).
Clinical images were provided; these images were not necessary to establish substantial equivalence based on the superior performance in comparison to the predicate based on laboratory testing and based on the use of a detector scintillator material that is already on the marketplace; however, they provide further evidence in addition to the laboratory performance data to show that the complete system works as intended.
There was no significant difference between the images of the CareView 1800R and those of the predicate device.
#### 10. Conclusion [21 CFR 807.92(b) (3)]
In accordance with the Federal Food, Druq and Cosmetic Act, 21 CFR Part 807 and based on the information provided in this premarket notification, the CareView 1800R X-ray flat panel detector is substantially equivalent to predicate device CXDI-40EG (K050987). Both propose and predicate devices are same or very similar in the intended use, the design principle, the applicable standards and specification. Some characteristics, for example, the detector size, pixel pitch, weight and ADC digitization, X-ray absorber, storage condition are different. However the test reports in this submission documents provide demonstration that these differences do not raise any new questions of safety and effectiveness. Therefore, CareRay Digital Medical System Co., Ltd. concludes the CareView 1800R X-ray flat panel detector is substantially equivalent with the predicate device CXDI-40EG (K050987) of Canon Inc.
