## Dear Mr. Woodard:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

| Device<br>Description: | The DIGITAL RADIOGRAPHY CXDI-Elite, also called the DIGITAL<br>RADIOGRAPHY E1, (hereinafter referred to as CXDI-Elite) is a solid-state x-ray<br>imager. The CXDI-Elite is a series of detectors, and in the predicate device consists of<br>the CXDI-720C Wireless detector unit, also called the AR-E3543W detector. The<br>detector intercepts x-ray photons, and the scintillator emits visible spectrum photons<br>that illuminate an array of photodetectors that create electrical signals. After the<br>electrical signals are generated, the signals are converted to digital values, and the<br>images will be displayed on monitors. The digital value can be communicated to the<br>operator console via a wired or wireless connection. | |
| | The subject of this Special 510(k) submission is a change to the CXDI-Elite to add new<br>detectors, the CXDI-420C Wireless (also called AR-E4343W) and the CXDI-420C<br>Fixed (also called AR-E4343S), to the CXDI-Elite series of detectors. In addition, a<br>Detector Stand (DS-01) has also been added as a component to be used with both the<br>CXDI-720C Wireless and CXDI-420C Wireless. Compatibility with the Power Box<br>(PB-01), a CXDI-Pro component that was cleared under K220098 has also been added.<br>The CXDI Control Software has been updated from V3.10.0.4 to V3.10.2.2 to fix some<br>bugs, update the GPU driver, and add several minor functional changes. Together, these<br>changes make up the CXDI-Elite. | |
| Indications for<br>Use: | The DIGITAL RADIOGRAPHY CXDI-Elite / E1 provides digital image capture for<br>conventional film/screen radiographic examinations. This device is intended to capture,<br>for display, radiographic images of human anatomy, and to replace radiographic<br>film/screen systems in all general purpose diagnostic procedures. This device is not<br>intended for mammography applications. | |
| Summary of<br>Technological<br>Characteristics: | Comparison with the predicate device shows the technological characteristics of the<br>CXDI-Elite is substantially equivalent to the predicate device. The flat panel detector<br>units are functionally similar, but one of the proposed detectors, CXDI-420C Fixed,<br>removes Standalone Mode as a photographing mode. | |

Summary of Non-Clinical / Test Data:

The fundamental scientific technology of the CXDI-Elite has not been modified. The changes are the addition of new detectors CXDI-420C Wireless (AR-E4343W) and CXDI-420C Fixed (AR-E4343S); the addition of an optional accessory, the Detector Stand (DS-01); the update to the CXDI Control Software from 3.10.0.4 to 3.10.2.2; and the update to the detector firmware from 02.00.00.03 to F2.00.03.00.

Evaluation of the addition of the new detector and optional accessories confirmed that the changes did not impact CXDI-Elite conformance with the U.S. Performance Standard for radiographic equipment and with relevant voluntary safety standards for Electrical safety and Electromagnetic Compatibility testing, specifically IEC standards 60601-1, 60601-1-2, 60601-2-54, and 60601-1-6.

These verification/validation activities successfully demonstrated that the device continues to meet the standards for the areas impacted by the modifications to the predicate device and raises no new questions regarding either safety or effectiveness when compared to the predicate device. Clinical testing is not necessary for the current submission, based on the minor differences from the predicate device. Adequate detector bench testing should be sufficient to demonstrate that the subject detector CXDI-Elite / E1 works as intended. Therefore, the verification/validation activities conducted support a determination of substantial equivalence for the CXDI-Elite.

The proposed device follows the applicable elements of the following FDA guidance documents: Guidance for the Submission of 510(k)s for Solid State X-ray Imaging Devices, Guidance for the Content of Premarket Submissions for Software contained in Medical Devices, Content of Premarket Submissions for Management of Cybersecurity in Medical Devices, Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process", Radio Frequency Wireless Technology in Medical Devices, and Pediatric Information for X-ray Imaging Device Premarket Notifications.

Canon Inc. considers the DIGITAL RADIOGRAPHY CXDI-Elite / E1 device to be Conclusion: substantially equivalent to the predicate device listed above. This conclusion is based on
