No
The summary describes a digital radiography system with hardware and software updates for image capture and display. There is no mention of AI, ML, or any related technologies for image analysis, interpretation, or other functions beyond basic image conversion and display. The performance studies focus on safety and equivalence to the predicate device, not on AI/ML performance metrics.
No
The device is described as an X-ray imager for capturing, displaying, and replacing film/screen systems in diagnostic procedures, which is a diagnostic function, not a therapeutic one.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is "intended to capture, for display, radiographic images of human anatomy, and to replace radiographic film/screen systems in all general purpose diagnostic procedures." This directly indicates its use in diagnostics.
No
The device description explicitly states that the CXDI-CS01 is a "solid-state x-ray imager" and a "series of detectors," which are hardware components. While it includes software (CXDI Control Software), it is not solely software.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states the device is for "digital image capture for conventional film/screen radiographic examinations" and to "capture, for display, radiographic images of human anatomy." This describes an imaging device used to visualize internal structures of the body.
- Device Description: The description details how the device intercepts x-ray photons and converts them into digital images for display. This aligns with the function of a medical imaging system.
- Lack of IVD Characteristics: IVD devices are used to examine specimens (like blood, urine, or tissue) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening. The provided text makes no mention of analyzing biological specimens or performing tests on samples outside the body.
Therefore, the DIGITAL RADIOGRAPHY CXDI-CS01 is a medical imaging device, not an In Vitro Diagnostic device.

Device Description
The DIGITAL RADIOGRAPHY CXDI-CS01 (hereinafter referred to as CXDI- CS01) is a solid-state x-ray imager. The CXDI-CS01 is a series of detectors and, in the predicate device submission (K222661), consists of the CXDI-702C Wireless, CXDI-402C Wireless, CXDI-710C Wireless, CXDI-810C Wireless, CXDI-410C Wireless, DIGITAL RADIOGRAPHY CXDI-Pro (CXDI-703C Wireless and CXDI-403C Wireless), and DIGITAL RADIOGRAPHY CXDI-Elite (CXDI-720C Wireless).
The CXDI-CS01 intercepts x-ray photons, and the scintillator emits visible spectrum photons that illuminate an array of photodetectors that create electrical signals. After the electrical signals are generated, the signals are converted to digital values. The digital values are sent to the PC via a wired or wireless connection, converted to images with the CXDI Control Software, and then displayed on the PC/monitors. The PC/monitors used with the CXDI-CS01 are not a part of this submission.
The subject of this Special 510(k) submission is the changes to the predicate CXDI- CS01, which include the addition of the DIGITAL RADIOGRAPHY CXDI-Pro detector (CXDI-803C Wireless) and the DIGITAL RADIOGRAPHY CXDI-Elite detectors (CXDI-820C Wireless and CXDI-420C Wireless) to the CXDI-CS01 series of detectors, a firmware update of the DIGITAL RADIOGRAPHY CXDI-Pro and DIGITAL RADIOGRAPHY CXDI-Elite detectors from 01.01.03.00 to 01.02.00.01 and from F2.00.03.00 to 02.01.04.00 respectively, and a CXDI Control Software version update from V3.10.2.2 to V3.10.2.6 to fix bugs. Together, these changes make up the CXDI-CS01.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Evaluation of the addition of the new detectors confirmed that the change did not impact the conformance of CXDI-CS01 with the U.S. Performance Standard for radiographic equipment and relevant voluntary safety standards for Electrical safety and Electromagnetic Compatibility testing, specifically IEC standards 60601-1, 60601-1-2, 60601-1-3, 60601-1-6, 60601-2-54, 62220-1, 62304, and 62366. The design control activities and biocompatibility evaluation successfully demonstrated that the modifications to the predicate device raise no new questions regarding either safety or effectiveness. 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-CS01, works as intended. Therefore, the verification/validation activities conducted support a determination of substantial equivalence for the CXDI-CS01.

The fundamental scientific technology of the CXDI-CS01 has not been modified. Summary of The major change is the addition of new detectors and component. Non-Clinical/ Test Data: Evaluation of the addition of the new detectors confirmed that the change did not impact the conformance of CXDI-CS01 with the U.S. Performance Standard for radiographic equipment and relevant voluntary safety standards for Electrical safety and Electromagnetic Compatibility testing, specifically IEC standards 60601-1, 60601-1-2, 60601-1-3, 60601-1-6, 60601-2-54, 62220-1, 62304, and 62366. The design control activities and biocompatibility evaluation successfully demonstrated that the modifications to the predicate device raise no new questions regarding either safety or effectiveness. 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-CS01, works as intended. Therefore, the verification/validation activities conducted support a determination of substantial equivalence for the CXDI-CS01. 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. Conclusion: Canon Inc. considers the DIGITAL RADIOGRAPHY CXDI-CS01 device to be substantially equivalent to the predicate device listed above. This conclusion is based on the similarities in primary intended use, principles of operation, functional design, and established medical use.
