2. Sample Size for the Test Set and Data Provenance
- Sample Size: The document does not explicitly state a specific number for the test set (clinical images). It mentions "sample radiographs of similar age groups and anatomical structures."
- Data Provenance: The clinical images were taken to demonstrate substantial equivalency between the 1417WCC and 1417WCA. The text does not specify the country of origin of the data, but it was reviewed by a "licensed US radiologist," implying the images might have been collected or evaluated in the US (or at least by a US-qualified professional). The study appears to be a prospective comparative study looking at new images generated by both devices for comparison.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications
- Number of Experts: One licensed US radiologist.
- Qualifications: "licensed US radiologist." No further details on years of experience or sub-specialization are provided.
4. Adjudication Method for the Test Set
The document does not explicitly state a formal adjudication method (e.g., 2+1, 3+1). It indicates that the images were "reviewed by a licensed US radiologist to render an expert opinion." This suggests a single expert review rather than a consensus-based adjudication process.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done
No, an MRMC comparative effectiveness study was not conducted in this submission. The study involved a single expert reviewer comparing images from the test device (1417WCC) and the predicate device (1417WCA).
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
Yes, a standalone performance assessment was done for the device's technical image quality parameters:
- MTF, DQE, and NPS tests were performed on both the 1417WCC and 1417WCA using "identical test equipment and same analysis method described by IEC 62220-1." These are objective, algorithm-only (device-only) measurements of physical imaging performance.
7. The Type of Ground Truth Used
- Non-clinical (Technical Performance): Objective measurements based on established standards (IEC 62220-1) for MTF, DQE, and NPS.
- Clinical (Subjective Evaluation): Expert opinion from a licensed US radiologist, serving as the ground truth for subjective image quality assessment and comparison. This would fall under expert consensus if there were multiple experts, but here it's a single expert's opinion.
8. The Sample Size for the Training Set
The document does not provide information on a training set. This device is a digital X-ray detector, which is hardware that captures images. It's not an AI/algorithm-based diagnostic device that typically requires a large training set of images with established ground truth for a machine learning model. The evaluation focuses on the performance characteristics of the hardware itself.
9. How the Ground Truth for the Training Set Was Established
As no training set is mentioned or applicable for this type of device (a digital X-ray detector hardware), this question is not relevant to the provided information.

4. Summary of Performance Testing
The 1417WCC flat panel detector is a modified version of 1417WCA (K130935), FDA cleared predicate device from Rayence. Indications for use, material, form factor, performance, and safety characteristics between 1417WCC and 1417WCA are identical.
The non-clinical test report and clinical consideration report were prepared and submitted to FDA separately to demonstrate the substantial equivalency between two similar detectors. The non-clinical test report contains the MTF, DQE and NPS test results of 1417WCC and 1417WCA by using the identical test equipment and same analysis method described by IEC 62220-1. The comparison of the MTF for 1417WCC
and 1417WCA detector demonstrated that the MTF of the 1417WCA detector performed almost same with 1417WCC. Therefore, the overall resolution performance and sharpness of 1417WCC is almost same with 1417WCA. The DOE represents the ability to visualize object details of a certain size and contrast. 1417WCC demonstrated higher DQE performance than 1417WCA at various spatial frequencies and provides almost same Signal-to Noise Ratio (SNR) transfer from the input to the output of a detector as a function of frequency. At the lowest spatial frequency. 1417WCC has a DOE of 74% and that of 1417WCA is 72%. 1417WCC also exhibited NPS which has almost same performance with 1417WCA. Therefore, the image quality of 1417WCC is found to be substantially equivalent to 1417WCA at the same patient exposure.
To further demonstrate the substantial equivalency of two devices, clinical images are taken from both devices and reviewed by a licensed US radiologist to render an expert opinion. Both the test subject (1417WCC) and control group (1417WCA) are evaluated and compared by taking sample radiographs of similar age groups and anatomical structures in accordance with the test protocol of diagnostic radiography evaluation procedure.
7
{7}------------------------------------------------
Based on the non-clinical and clinical consideration test and the outcome of a comparative review by an expert for both devices, we can claim the substantial equivalency between 1417WCC and its predicate device, 1417WCA in terms of image quality.
After comparing a broad review of plain radiographic images taken with the 1417WCC and the 1417WCA, the images obtained with the 1417WCC are comparable or superior to the same view obtained from a similar patient with the 1417WCA. In general, both the spatial resolution and soft tissue contrast are superior using the 1417WCC. Specifically, the soft tissues on extremity films were seen with better clarity. There is no difficulty in evaluating a wide range of anatomic structures necessary to provide a correct conclusion.
The manufacturing facility is in conformance with the design control procedure requirements and the relevant EPRC standards as specified in 21 CFR 802.30 and the records are available for review.
5. Summary for any testing in the submission:
