The OEC FluoroTrak 9800 Plus provides the physician with fluoroscopic imaging during diagnostic, surgical and interventional procedures. The surgical navigation feature is intended as an aid to the surgeon for locating anatomical structures anywhere on the human body during either open or percutaneous procedures. It is indicated for any medical condition that may benefit from the use of stereotactic surgery and which provides a reference to rigid anatomical structures such as sinus, skull, long bone or vertebra visible on fluoroscopic images.
The OEC FluoroTrak 9800 Plus is the result of mechanically integrating the Instatrak 3000 System with FluoroTrak Module (marketed by Visualization Technology, Inc.) into the workstation of the OEC 9800 Mobile Imaging System. The 9800 Mobile Imaging System is an image intensified fluoroscopic system consisting of a mobile C-arm and OEC Workstation. The C-arm supports the highvoltage generator, x-ray tube, x-ray controls, and image intensifier. The C-arm is designed to perform linear and rotational motions that allow the user to position the x-rav imaging components at various andles and distances with respect to the patient. The OEC workstation is a mobile platform that supports image display monitors, image processing and recording devices. The InstaTrak 3000 System is an image quidance system indicated for use during sinus, skull base, cranial and axial skeletal procedures. Using the InstaTrak 3000, the surgeon can readly identify the immediate location and position of the surgical instrument during the indicated procedure. The InstaTrak 3000 System allows the surgeon to view reconstructed twodimensional images of the patient's analomy in response to an electromagnetically tracked surgical instrument. This indicates the position of the tracked surgical instrument with regard to the patient's analomy based on pre-operative medical images.
Here's an analysis of the provided text regarding the OEC FluoroTrak 9800 Plus, focusing on acceptance criteria and study details.
Important Note: The provided 510(k) summary is very brief and primarily focuses on regulatory compliance and substantial equivalence to predicate devices, rather than detailed performance studies and acceptance criteria as might be found in a more comprehensive clinical trial report. As such, many of the requested fields below will indicate "Not provided" or "Not applicable" based on the limited information available in this summary.
Acceptance Criteria and Device Performance
The provided document (a 510(k) summary) does not explicitly state acceptance criteria in terms of specific performance metrics (e.g., accuracy, sensitivity, specificity, resolution) for the OEC FluoroTrak 9800 Plus in its primary function as a fluoroscopic imaging system or its surgical navigation feature. Instead, the acceptance criteria are implicitly tied to regulatory compliance with established product safety and performance standards, and demonstrating substantial equivalence to predicate devices.
1. Table of Acceptance Criteria and Reported Device Performance

| Intended use remains the same as described in original 510(k)s for predicate devices. | The intended use of both the InstaTrak 3000 System with FluoroTrak Module and the OEC 9800 Mobile Imaging System remains the same. (Statement of fact) |
Rationale for Table Content:
The 510(k) summary is a regulatory document to establish "substantial equivalence" to a legally marketed predicate device. It demonstrates this primarily through compliance with recognized standards and a comparison of technological characteristics and intended use. Specific quantitative performance data and acceptance criteria for this particular device are not detailed in this summary. The "reported device performance" is thus a statement of the device's design adherence to these standards and the FDA's finding of substantial equivalence.
Study Details
Based on the provided 510(k) summary, a formal clinical study with detailed performance metrics, test sets, expert adjudication, or MRMC comparisons is not described. The submission relies on establishing substantial equivalence to previously cleared devices (OEC 9800 Mobile Digital Imaging System and InstaTrak 3000 System with FluoroTrak Module) and compliance with relevant safety and performance standards. The integration of two existing systems into one does not typically require a new, extensive clinical performance study if the fundamental component functions and intended uses remain unchanged and safety is addressed through component compliance.
2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)
- Not provided. The document does not describe a specific test set or data provenance for a performance study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)
- Not provided. No details on experts or ground truth establishment for a performance study are mentioned.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set
- Not provided. No adjudication method is mentioned, as no specific test set is detailed.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable / Not provided. The device described is a fluoroscopic imaging system with a surgical navigation feature, not an AI-assisted diagnostic tool that would typically undergo MRMC studies to evaluate reader improvement. The 510(k) summary does not mention any AI components or MRMC studies.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not applicable / Not provided. The device is a physical medical imaging and navigation system, not a standalone algorithm. Performance is integrated with human use.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Not provided. Details on ground truth for performance evaluation are not discussed in this summary. The "ground truth" for regulatory clearance is implicitly the established safety and effectiveness of the predicate devices and compliance with recognized standards.
8. The sample size for the training set
- Not applicable / Not provided. The document does not describe an algorithm requiring a training set in the context of machine learning.
9. How the ground truth for the training set was established
- Not applicable / Not provided. As no training set is described for an algorithm, this information is not relevant to the provided summary.
