20.1" Monochrome LCD Monitor, RadiForce G20 is intended to be used in displaying for diagnosis of X-ray or MRI.

RadiForce G20 is 20.1 inches monochrome monitor for medical use. This model has specification of resolution in 1600 x 1200 or 1200 x 1600 and is certified for IEC60601-1 of medical safety standard.

This document is a 510(k) summary for a medical display monitor (EIZO RadiForce G20), indicating it is a hardware device. The questions provided are typically for AI/software devices. This device is a monitor, which is a display hardware, and therefore the concepts of "acceptance criteria for an algorithm", "sample size for test/training set", "ground truth", "experts", "MRMC study", and "standalone performance" do not directly or entirely apply in the same way they would for a diagnostic AI algorithm.

However, I will interpret the request to provide the closest applicable information based on the provided text, focusing on how the device's technical specifications demonstrate its suitability for medical imaging display.

Here's an analysis based on the provided text:

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

Since this is a hardware device (a monitor), "acceptance criteria" are typically defined by its technical specifications and compliance with relevant medical standards, and "reported device performance" refers to how the device meets those specifications. The provided document details the specifications of the new device (G20) and compares them to a predicate device (FC-2091).

| Characteristic (Acceptance Criteria Proxy) | Predicate Device (FC-2091) Performance | New Device (RadiForce G20) Performance | Compliance/Notes |
| Panel Size (Diagonal) | 20.8" | 20.1" | Different, but both are suitable for medical display. |
| Native Resolutions | 2048 x 1536 (landscape) | 1600 x 1200 (landscape) | Lower resolution, but still specified for medical use and considered substantially equivalent to the predicate. |
| Brightness | 650 cd/m² | 700 cd/m² | Improved brightness, favorable for medical imaging. |
| Contrast Ratio | 600 : 1 | 1000 : 1 | Improved contrast, favorable for medical imaging. |
| Response Time | 50 ms | 30 ms | Improved response time, favorable for dynamic content. |
| Certifications & Standards | TUV/GM, CE, CB, EN60601-1, UL2601-1, CSA C22.2 No. 601-1, FCC-A, Canadian ICES-003-A, VCCI-A, FDA 510(k) | TUV/GM, c-TUV, CE, CB, EN60601-1, UL2601-1, CSA C22.2 No. 601-1, FCC-A, Canadian ICES-003-A, TUV/S, VCCI-A | Both devices meet a comprehensive set of international and national safety and electromagnetic compatibility standards including IEC60601-1 (medical safety), which is a key acceptance criterion for medical device monitors. |

The study proves the device meets the acceptance criteria by demonstrating that its technical specifications are either equivalent to or improved compared to a predicate device (EIZO FC-2091), which has already received 510(k) clearance for medical use. The critical point is that these specifications, coupled with compliance to medical safety and EMI/EMC standards (like EN60601-1), ensure the device is suitable for its intended use in displaying X-ray or MRI images for diagnosis.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This device is a hardware monitor, not an AI algorithm that processes data. Therefore, there is no "test set" in the sense of a dataset of medical images, nor is there "data provenance" (country of origin, retrospective/prospective). The "test" for a monitor involves engineering verification and validation of its physical and performance characteristics (e.g., brightness, contrast, resolution, compliance with electrical safety standards, electromagnetic compatibility). These tests are typically conducted in a laboratory setting by the manufacturer as part of their quality management system.

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)

Again, this is not applicable to a medical display monitor in the way it applies to an AI algorithm. There is no "ground truth" to establish from medical images using expert readers for the monitor itself. The "ground truth" for a monitor's performance is objective technical measurement against its specifications and industry standards. For example, brightness is measured with a photometer, and resolution is verified against display drivers.

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

Not applicable. This concept pertains to establishing consensus ground truth among multiple human readers for an AI algorithm's test set. A medical display monitor does not involve such an adjudication process for its own performance evaluation.

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. An MRMC study is used to assess the impact of an AI algorithm on human reader performance for diagnostic tasks. This device is a display monitor; its function is to render images, not to provide diagnostic assistance via AI.

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

Not applicable. A "standalone" performance evaluation refers to an AI algorithm's diagnostic accuracy without human interaction. This device is a passive display unit.

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

Not applicable in the context of diagnostic AI. For a monitor, the "ground truth" is its physical and performance specifications as measured by engineering and quality assurance tests. These include measurements of luminance, contrast, uniformity, color accuracy (for color displays, though this is a monochrome monitor), pixel defects, viewing angles, and compliance with electrical, safety, and EMC standards.

8. The sample size for the training set

Not applicable. This device is hardware; it does not employ machine learning or require a "training set."

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

Not applicable (as above).
