The summary describes a mobile x-ray system with hardware and software upgrades for imaging capabilities and integration with navigation systems. There is no mention of AI or ML in the intended use, device description, or performance studies. The performance studies focus on image quality, motion compensation, and extended field of view, not AI/ML algorithm performance.
No
The device is an imaging system (mobile x-ray system) used for diagnostic purposes, not for treating diseases or conditions.
Yes
The device is an x-ray system that provides 2D and 3D information of anatomic structures, which is used to diagnose medical conditions, and clinical studies involved patient imaging under standard operating conditions to validate new features' impact in routine diagnostic settings.
No
The device is described as a "mobile x-ray system" consisting of a "ring gantry and respective arms carrying the X-Ray source" and "all necessary electronic and components along with low-level software". This clearly indicates the presence of significant hardware components beyond just software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body, such as blood, urine, or tissue, to provide information for diagnosis, monitoring, or screening.
- Device Function: The ImagingRing m is an X-ray system that produces images of the internal structures of the body. It does not analyze specimens taken from the body.
- Intended Use: The intended use clearly states it's for "2D planar and fluoroscopic and 3D imaging for adult and pediatric patients" to obtain "information of anatomic structures." This is in vivo imaging, not in vitro analysis.
The device is an imaging system used directly on the patient, which falls under the category of medical devices but not specifically In Vitro Diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Study Type: Non-clinical (cadaver studies, evaluations at reference customer sites) and clinical studies.
Sample Size: Not specified.
Data Source: Highridge Cadaver Lab in the US, Paracelsus Medical University (Austria), and clinical settings.
Annotation Protocol: Not specified.
Key Investigations and Findings:
- X-ray energy option (140 kVp): Cadaver studies compared 3DCBCT images acquired at 120 kVp and 140 kVp. The increased tube voltage does not negatively impact image quality and provides higher penetration, particularly for larger patients or cases involving metallic implants.
- Infrared-based motion compensation: Assessed through both cadaver and clinical studies. It was confirmed that this feature improves image quality without altering total radiation dose by reducing motion-related artifacts.
- Extended Field of View (FOV) techniques (longitudinally extended 3D imaging and 2D topogram scanning): Evaluated through a combination of clinical and cadaver studies. These features enhance workflow efficiency while maintaining high image quality and adhering to radiation principles, allowing for better anatomical coverage and more precise planning of subsequent CBCT scans.
Conclusion: The enhancements (higher X-ray energy, motion compensation, and extended FOV capabilities) introduced in the device do not negatively impact its clinical performance and instead provide tangible benefits in patient imaging, demonstrating substantial equivalence.

Non-Clinical and/or Clinical Tests Summary & Conclusions 21 CFR 807.92(b)
Summary of Non-Clinical and Clinical Testing Supporting Substantial Equivalence
As part of the comprehensive non-clinical testing conducted to evaluate the subject device and its new features, multiple studies have been carried out in collaboration with renowned institutions. These investigations encompass a variety of testing environments, including cadaver studies (e.g. at Highridge Cadaver Lab in the US, Paracelsus Medical evaluations at reference customer sites, to ensure a thorough assessment of the device's performance, safety, and usability.
Overview of Testing Approach
The testing framework incorporated both non-clinical methodologies to provide a robust foundation for determining substantial equivalence. Non-clinical testing includes performed at multiple institutions, aiming to simulate real-world conditions while maintaining control variables. Clinical studies involved patient imaging under standard operating conditions to validate the new features' impact in routine diagnostic settings.
Key Investigations and Findings
One of the primary objectives was to analyze whether X-ray energy option (140 kVp) affects diagnostic accuracy and usability. Cadaver studies compared 3DCBCT images acquired at 120 kVp, demonstrating that the increased tube voltage does not negatively impact image quality. Instead, higher penetration particularly for larger patients or cases involving metallic implants.
The implementation of infrared-based motion was assessed through both cadaver and clinical studies, evaluating its effectiveness in reducing motion-related artifacts. By acquiring and reconstructing images with and without motion compensation, it was confirmed that this feature improves mage quality without altering total radiation dose. This finding is particularly relevant in cases where respiratory motion or involuntary patient movement could otherwise degrade image clarity.
The introduction of extended Field of View (FOV) techniques, including longitudinally extended 3D imaging and 2D topogram scanning, was also rigorously evaluated. These features alow for better anatomical coverage, facilitating more precise planning of subsequent CBCT scans. Through a combination of clinical and cadaver studies, it was demonstrated that extended FOV scanning enhances workflow efficiency while maintaining high image quality and adhering to radiation principles.

Conclusion:
Across all evaluated features, clinical and non-clinications introduced in the subject device do not neqatively impact its clinical performance. Instead, enhancements such as higher X-ray energy, motion compensation, and extended FOV capabilities provide tangible benefits in patient imaging, these non-clinical imaging studies, through the comparison of image quality, artifacts, anatomical representation, and dose, demonstrate the substantial equivalence of the devices with the tested new features to their respective base versions or similar devices.
