Device Story

Smart-C is a battery-powered, mobile mini C-arm fluoroscopic X-ray system. Input: X-ray images acquired via CMOS flat panel detector and X-ray source monoblock. Transformation: System processes X-ray signals into digital images; wireless transfer (IEEE 802.11AC) to a tablet computer workstation. Output: Real-time fluoroscopic images displayed on a 13" touchscreen tablet or optional 27" monitor cart. Usage: Point-of-care in clinical, surgical, or emergency settings; operated by physicians/surgeons. Workflow: Wireless footswitch initiates acquisition; tablet provides image processing, storage, and display. Clinical impact: Enables real-time visualization during orthopedic/extremity procedures; portability allows flexible positioning in OR or clinical venues. Benefits: Cord-free operation improves workflow; diagnostic image quality supports surgical decision-making.

Clinical Evidence

Bench testing included anthropomorphic phantom imaging, image quality performance testing (contrast/spatial resolution), and dynamic resolution assessment. Clinical utility was demonstrated via a Clinical Imaging Evaluation using cadaver subjects representing extremity imaging (including shoulders) across standard and low-dose modes. A Pediatric Imaging Usability Evaluation confirmed suitability for extremity positioning in neonatal and infant patients. Physician feedback indicated image quality was at least as good as the predicate device.

The mechanical arrangement between these components is almost identical. One difference is the main power source being a Li-ion battery pack in the Smart-C and standard mains power supply for the Mobile DI. The safety and efficacy considerations of battery power for the Smart-C are considered and mitigated through the Risk Analysis and design mitigations. > A significant difference between the 2 devices is the use of a standard computer and imaging monitor for the Mobile DI, and the use of a Tablet Computer with integrated touchscreen display as the primary workstation for the Smart-C. To evaluate the substantial equivalence of the tablet computer/display with a standard imaging monitor, we referred to the FDA Guidance Display Devices for Diagnostic Radiology. In addition to the display data, a Qualified Expert Evaluation of the diagnostic ability of the tablet display device was performed by 2 independent board-certified physicians. The conclusion of the expert evaluators is that the image quality of the tablet is diagnostic in all presented cases, and thus substantially equivalent to a standard surgical monitor for the intended use of the Smart-C device. {7}------------------------------------------------ Another significant difference between the units is that the Smart-C uses WiFi technology to wirelessly transfer the images from the x-ray detector to the Tablet computer for display and processing. This allows the display device to be positioned independently of the Smart-C. and within the physicians preferred field of view. This improves the workflow and ease of imaging. FDA guidance documents used in the development of the device include Radio Frequency Wireless Technology in Medical Devices, and Content of Premarket Submissions for Management of Cybersecurity in Medical Devices. Summary Reports were prepared to show how the Smart-C complies with these guidance documents. ### Summary Bench Testing A Qualified Expert Evaluation of the image quality of the Smart-C was performed by independent physicians utilizing images obtained from anthropomorphic phantoms. An additional Image Quality Performance test was completed using image quality phantoms for contrast and spatial resolution. Dynamic image resolution was assessed using rotation of a phantom with 2 lead dots. In addition to the image quality bench studies, system verification and validation testing including hazard mitigation has been performed to demonstrate the Smart-C system meets design input and user needs. The Smart-C system has been tested to show compliance with the applicable IEC series of x-ray performance standards, including IEC60601-2-54. It also meets all applicable 21CFR Subchapter J performance standards. ### Summary Clinical Testing The clinical utility of the Smart-C was demonstrated by performing a Clinical Imaging Evaluation. Cadaver subjects were chosen to represent the range of extremity imaging. including shoulders. To represent a range of imaging conditions the testing was performed in both standard fluoro and in low-dose mode. Image enhancement algorithms like recursive filtering and edge enhancement were evaluated, and suitable conditions determined for their use. Patient positioning considerations for adult patients were considered in a separate usability study. To address the special needs of neonatal and infant patients, a Pediatric Imaging Usability Evaluation was performed. This included the additional consideration of patient positioning for these very small size subjects. The Smart-C is not indicated for wholebody imaging of pediatric patients, so this study was limited to extremity positioning. Based on physician feedback, the clinical images obtained with the Smart-C were at least as good as the predicate device. There were no new concerns regarding patient positioning, including for neonatal and infant patients. - Conclusion: The Smart-C and the predicate device both have the same intended use to provide physicians with real-time fluoroscopic visualization of anatomy of extremities. Thev meet the same recognized performance and safety standards, and to conform to FDA guidance regarding solid-state x-ray imaging systems. The designs are based on the same modern technologies using a compact monoblock x-ray generator and flat-panel x-ray {8}------------------------------------------------ detector, operating at similar power levels. Differences in technological characteristics (battery power, wireless image transfer, tablet display, and wireless footswitch) have been evaluated for safety hazards utilizing risk management activities and risk analysis. The design mitigations were successfully tested during verification and validation. The Smart-C has been evaluated by numerous physicians and surgeons for image quality and usability on anthropomorphic phantoms, image quality phantoms, and cadaver subjects in clinical settings. They determined that it performs at least as well as the predicate device, and that it is efficacious for the intended uses. We conclude that the Smart-C is of comparable type and substantially equivalent to the predicate device Orthoscan Mobile DI (K113708) and is safe and effective for its intended use.
