The XiScan Expert Imaging Systems are intended for fluoroscopic imaging of patient extremities.
The XiScan Expert Imaging Systems are compact, mobile, mini c-arm systems specifically designed for fluoroscopic imaging of patient extremities. Two versions are available: the XiScan Office Expert and the XiScan Surgical Expert. The systems can be operated in either manual or automatic exposure rate control (AERC) modes, with options of reduced radiation LOW DOSE and high resolution STANDARD DOSE when using AERC. Both systems offer a range of options for image manipulations. The Surgical Expert also features a remote, hand-held keypad to manage on-screen patient information and image storage.
The provided text is a 510(k) summary for the XiScan Expert Imaging Systems, which are mini c-arm systems for fluoroscopic imaging. It primarily focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria through a dedicated study.
Therefore, many of the requested details about acceptance criteria, study design, and ground truth establishment are not present in this type of regulatory submission, as the requirement for 510(k) is to show equivalence.
However, I can extract the available information:
1. Table of Acceptance Criteria and Reported Device Performance:
No specific acceptance criteria or performance metrics (e.g., sensitivity, specificity, accuracy) are reported in this 510(k) summary. The document relies on a comparison to predicate devices.
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Not specified directly in this document. The basis for substantial equivalence is listed below. | Not specified directly in this document. The basis for substantial equivalence is listed below. |
| Basis for Substantial Equivalence: | The XiScan Expert Imaging Systems have the same intended use and similar technical specifications compared to predicate devices (Fluoroscan Premier, Fluoroscan OfficeMate, OEC Mini 6600 Digital Mobile C-arm). |
| All devices are mini c-arm systems with similar technique factors, SIDs, field-of-view sizes, and image enhancement options. | |
| A bench test confirmed that patient X-ray exposure rates for imaging various anatomies are similar. |
2. Sample Size for the Test Set and Data Provenance:
No specific "test set" in the context of evaluating diagnostic performance is mentioned. The assessment was based on a "bench test comparison" of device specifications and X-ray exposure rates.
- Sample size for test set: Not applicable/not specified for a typical diagnostic performance study.
- Data provenance: The "bench test comparison" implies data was generated directly from the devices being compared, likely within a controlled test environment. Country of origin not specified. Retrospective/prospective not applicable in this context.
3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications:
Not applicable. This document describes a comparison of technical specifications and X-ray exposure, not a diagnostic performance study requiring expert ground truth for interpretation.
4. Adjudication Method for the Test Set:
Not applicable. No diagnostic interpretation or "test set" requiring adjudication is mentioned.
5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:
No. This document does not mention an MRMC study or any study evaluating the effect of AI assistance on human readers. The device itself is an imaging system, not an AI-based diagnostic tool.
6. Standalone (Algorithm Only) Performance Study:
No. The device is an imaging system, not an algorithm. Therefore, a standalone algorithm performance study is not applicable.
7. Type of Ground Truth Used:
Not applicable for a typical diagnostic performance study. The "ground truth" for the bench test comparison would be adherence to technical specifications and measured X-ray output, which would be objectively determined.
8. Sample Size for the Training Set:
Not applicable. This document describes a physical medical imaging device, not a machine learning algorithm that requires a training set.
9. How Ground Truth for the Training Set Was Established:
Not applicable, as there is no training set for a machine learning algorithm.

5. INTENDED USE
The XiScan Expert Imaging Systems are intended for fluoroscopic imaging of patient extremities.
BASIS FOR SUBSTANTIAL EQUIVALENCE 6.
The XiScan Expert Imaging Systems have the same intended use, and similar technical specifications, as compared to the predicate devices. All devices are mini c-arm systems with similar technique factors, SIDs, field-of-view sizes, and image enhancement options. A bench test comparison of the devices confirmed that the patient X-ray exposure rates for imaging various anatomies are similar. Based on these comparisons, the XiScan Expert Imaging Systems are substantially equivalent to the Fluoroscan and OEC mini c-arm systems.

Dear Ms. Hemeon-Heyer:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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. You may, therefore, market the device, subject to the general controls provisions of the Act. 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.
If your device is classified (see above) into either class III (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General requlation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP requlation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4613.
