This document describes the regulatory submission for Sony LMD-X310S, LMD-X310MD, LMD-X310NB, LMD-X550S, LMD-X550MD, and LMD-X550NB LCD Monitors. The submission focuses on demonstrating substantial equivalence to a predicate device, the SONY LMD-2451MT LCD MONITOR.
Here's an analysis of the requested information based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The document does not present a formal table of "acceptance criteria" with specific numerical values for performance metrics that the device had to meet. Instead, it states that the devices conformed to recognized standards and that bench testing "met pre-defined design and performance acceptance criteria."
The performance characteristics are largely presented in a comparative table with the predicate device, focusing on technological characteristics rather than specific "acceptance criteria" against which performance was measured.
Functional Performance Comparison (derived from Section 5.6):

2. Sample Size Used for the Test Set and Data Provenance
The document mentions "bench testing as part of required performance verification and validation activities" (Section 5.7) and states that "Results show that the subject device has met pre-defined design and performance acceptance criteria." However, it does not specify any sample size for the test set or the provenance of any data. The testing appears to be functional and safety testing of the device itself, rather than testing on a dataset of medical images.
3. Number of Experts Used to Establish Ground Truth and Qualifications
Not applicable. This submission focuses on the safety and performance of a medical display monitor and its substantial equivalence to a predicate device, not on diagnostic accuracy based on expert interpretation of medical images. Therefore, no experts were used to establish ground truth for a test set of medical images, as such a test set is not described.
4. Adjudication Method for the Test Set
Not applicable. As no test set involving expert interpretation is described, there is no mention of an adjudication method.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done
No. The document explicitly states: "No clinical data was collected to support substantial equivalence between the subject and predicate devices" (Section 5.8). Therefore, no MRMC study was performed, and no effect size for human reader improvement with AI assistance is provided.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is an LCD monitor, a hardware device for displaying images, not an algorithm or AI system for image interpretation. Therefore, a standalone algorithm performance study is not relevant.
7. The Type of Ground Truth Used
The "ground truth" for the device's performance is implicitly defined by its ability to meet recognized performance and safety standards (e.g., ANSI/AAMI ES60601-1, IEC 60601-1-2) and pre-defined design specifications through functional bench testing. It's not related to medical image interpretations, pathology, or outcomes data, as this is a display device.
8. The Sample Size for the Training Set
Not applicable. As the device is a medical monitor and not an AI/ML algorithm, there is no training set involved.
9. How the Ground Truth for the Training Set was Established
Not applicable. Since there is no training set, this question is not relevant.
