1717SGN and 1717SCN Digital Flat Panel X-Ray Detector are indicated for digital imaging solution designed for general radiographic system for human anatomy. They are intended to replace film or screen based radiographic systems in all general purpose diagnostic procedures. Not to be used for mammography.

Device Description

1717SGN and 1717SCN digital solid state X-ray detectors are based on flat-panel technology. Both radiographic image detector and processing units consist of a scintillator coupled to an a-Si TFTsensor. A digital flat panel X-ray detector needs to be integrated with a radiographic imaging system. It can be utilized to capture and digitalize X-ray images for radiographic diagnosis. The RAW files can be further processed as DICOM compatible image files by separate console SW (not part of this 510k submission) for a radiographic diagnosis and analysis.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the Rayence Co., Ltd.'s 1717SGN / 1717SCN Digital Flat Panel X-ray Detectors. The submission aims to demonstrate substantial equivalence to predicate devices (LLX240AB01 and LTX240AA01-A manufactured by Samsung Mobile Display Co., Ltd.).

This document outlines the testing conducted to support the claim of substantial equivalency but does not provide specific, quantifiable acceptance criteria in a table format with corresponding pass/fail results or detailed device performance metrics relevant to an AI/Machine Learning context. The focus is on demonstrating that the new devices perform comparably to (or better than) existing predicate devices for general radiographic use, primarily through non-clinical bench testing and a limited clinical consideration.

Therefore, many of the requested elements for an AI/ML device's acceptance criteria and study proving performance cannot be fully extracted or are not applicable from this document, as it pertains to a hardware medical device submission.

Here's an attempt to address the points based on the provided text, highlighting where information is missing or not applicable:

Acceptance Criteria and Study Proving Device Meets Acceptance Criteria

This document describes the 510(k) submission for a digital flat panel X-ray detector, not an AI/Machine Learning diagnostic algorithm. Therefore, the typical acceptance criteria and study designs for AI/ML devices (e.g., sensitivity, specificity, AUC, MRMC studies, ground truth establishment for AI training/testing sets) are not directly applicable or detailed in this submission.

The general acceptance criteria for this hardware device revolve around demonstrating substantial equivalence to predicate devices in terms of:

Safe and effective operation.
Having the same intended use.
Similar technological characteristics.
Performance that is comparable or superior to the predicate.

1. A table of acceptance criteria and the reported device performance

The document does not present acceptance criteria in a quantitative table format suitable for an AI/ML context (e.g., minimum sensitivity, specificity). Instead, performance is reported comparatively against the predicate devices.

Acceptance Criterion (Implicit)	Device Performance (1717SGN / 1717SCN)
Non-clinical Performance
MTF (Modulation Transfer Function)	Performed "better" than predicate devices (LLX240AB01/LTX240AA01-A).
DQE (Detective Quantum Efficiency)	1717SGN: Higher DQE than LLX240AB01 at all spatial frequencies and superior Signal-to-Noise Ratio (SNR) transfer.
	1717SCN: Higher DQE at high spatial frequencies (1 lp/mm to 3 lp/mm).
NPS (Noise Power Spectrum)	Test results provided (details not explicitly stated as comparative data).
Clinical Performance (Qualitative Comparison)
Spatial Resolution	"comparable or superior" to predicate. Specifically, "superior" for 1717SCN/1717SCN (likely a typo, refers to subject devices).
Soft Tissue Contrast	"comparable or superior" to predicate. Specifically, "superior" for 1717SCN/1717SCN. Soft tissues on extremity films seen with "better clarity".
Evaluation of Anatomic Structures	No difficulty in evaluating a wide range of anatomic structures necessary to provide a correct conclusion.
Safety & Electrical Performance	Passed IEC 60601-1:2005 + CORR.1(2006) + CORR(2007) and IEC 60601-1-2:2007 (EMC).

2. Sample size used for the test set and the data provenance

Test Set (Clinical Consideration): "sample radiographs of similar age groups and anatomical structures" were taken. A specific number of cases or images is not provided.
Data Provenance: Not explicitly stated, but given the manufacturer is Rayence Co., Ltd. (Korea) and the consulting firm is in Houston, TX, the data could be from various geographies. The clinical consideration involved a "licensed US radiologist", suggesting the review was done in the U.S. There is no indication of retrospective or prospective study design, but the description "After comparing a broad review of plain radiographic images taken with..." suggests an observational review rather than a formal prospective clinical trial.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Number of Experts: "a licensed US radiologist" (implies one expert).
Qualifications: "licensed US radiologist." No specific experience level (e.g., 10 years) is provided.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Adjudication Method: "reviewed by a licensed US radiologist to render an expert opinion." This implies no formal adjudication among multiple readers, as only one expert is mentioned. The comparison was a qualitative expert review.

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

No MRMC study or AI assistance: This submission is for a digital X-ray detector, not an AI-powered diagnostic tool. Therefore, an MRMC study related to AI assistance was not applicable and not performed.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable: This is a hardware device. No diagnostic algorithm is being evaluated in a standalone capacity.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

Type of Ground Truth (for clinical consideration): The "ground truth" was the expert opinion of a single licensed US radiologist comparing images from the new devices against images from the predicate devices. This is a qualitative comparison, not a formal diagnostic ground truth like pathology.

8. The sample size for the training set

Not applicable: This is a hardware device; there is no mention of a "training set" in the context of an AI/ML algorithm.

9. How the ground truth for the training set was established

Not applicable: No training set for an AI/ML algorithm was used.

7. Summary of Performance Testing

1717SGN and 1717SCN Digital Flat Panel X-Ray Detector have the same indications for use, material, form factor, performance, and safety characteristics compared to the predicate devices, LLX240AB01 and LTX240AA01-A, respectively.

The non-clinical test report and clinical consideration report for each subject device were prepared and submitted to FDA separately to demonstrate the substantial equivalency of the subject devices compared to each respective predicate device. The non-clinical test report contains the MTF, DQE and NPS test results of 1717SGN and 1717SCN by using the identical test equipment and same analysis method described by IEC 6220-1. The comparative result of the MTF test for 1717SGN and 1717SCN detector with respective predicate demonstrated that the MTF of the both 1717SGN and 1717SCN performed better compared with the predicate devices. The DQE represents the ability to visualize object details of a certain size and contrast. 1717SGN demonstrated higher DQE performance than LLX240AB01 at all spatial frequencies as well as superior Signal-to Noise Ratio (SNR) transfer from the input to the output of the detector as a function of frequency. 1717SCN has higher DQE performance at high spartial frequencies, especially from 11p/mm to 3 lp/mm.

To further demonstrate the substantial equivalency of two devices, clinical images are taken from both subject devices and reviewed by a licensed US radiologist to render an expert opinion. Both the test subject (1717SGN and 1717SCN) and control group (LLX240AB01 and LTX240AA01-A) 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.

After comparing a broad review of plain radiographic images taken with 1717SGN / 1717SCN and LLX240AB01 / LTX240AA01-A, the images obtained with the 1717SGN / 1717SCN are comparable or superior to the same view obtained from a similar patient with the LLX240AB01 / LTX240AA01-A. In general, both the spatial resolution and soft tissue contrast are superior

{9}------------------------------------------------

using the 1717SCN / 1717SCN digital flat panel detector. 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.

Clinical images were provided; these images were not necessary to establish substantial equivalence based on the modifications to the device but they provide further evidence in addition to the laboratory performance data to show that the subject devices operate as indicated.

Based on the non-clinical bench testing supplemented by the clinical consideration and the outcome of a comparative review by an expert for both devices, the sponsor demonstrated that the subject devices operate as indicated and are substantially equivalent to the predicate devices in terms of safety and effectiveness.

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.

8. Summary for any testing in the submission:

Electrical, mechanical, environmental safety and performance testing according to standard IEC 60601-1: 2005 + CORR.1(2006) + CORR(2007) (Medical electrical equipment Part 1:General requirements for basic safety and essential performance) was performed, and EMC testing were conducted in accordance with standard IEC 60601-1-2:2007.
