This product is indicated for use in displaying radiological images (including full-field digital mammography and digital breast tomosynthesis) for review, analysis, and diagnosis by trained medical practitioners.

Device Description

RadiForce RX1270 is a color LCD monitor for viewing medical images including those of mammography. The color panel employs in-plane switching (IPS) technology allowing wide viewing angles and the matrix size (or resolution) is 4.200 x 2.800 pixels (12MP) with a pixel pitch of 0.1554 mm. With the matrix size (or resolution) of 4.200 x 2.800 pixels (12MP), the RX1270 is an optimal replacement for traditional dual head 2,048 x 2,560 pixels (5MP) display installations. Since factory calibrated display modes, each of which is characterized by a specific tone curve (including DICOM GSDF), a specific luminance range and a specific color temperature, are stored in lookup tables within the monitor, the tone curve is e.g. DICOM compliant regardless of the display controller used. There are two model variations, RX1270 and RX1270-AR. The difference of the two variations is the surface treatment of the display screens; the surface treatment of the RX1270 is Anti-Glare (AG) treatment and that of the RX1270-AR is Anti-Reflection (AR) coating. RadiCS is application software to be installed in each workstation offering worry-free quality control of the diagnostic monitors including the RadiForce RX1270 based on the OC standards and guidelines and is capable of quantitative tests and visual tests defined by them. The RadiCS and its subset, RadiCS LE, are included in this 510(k) submission as an accessory to the RadiForce RX1270.

AI/ML Overview

This document describes the EIZO RadiForce RX1270 and RX1270-AR diagnostic displays. It's a 510(k) submission to the FDA, demonstrating substantial equivalence to a predicate device, the RadiForce RX560. The document focuses on the technical specifications and bench testing of a medical display, not an AI-powered diagnostic device. Therefore, much of the requested information regarding AI study design (sample size for test/training sets, data provenance, expert ground truth, adjudication, MRMC studies, standalone performance) is not applicable or cannot be extracted from this document, as it pertains to AI/CADe systems, not display monitors.

Here's a breakdown of the available information:

1. Table of Acceptance Criteria and Reported Device Performance

The document doesn't provide a specific table of acceptance criteria with numerical targets and direct performance outcomes for each criterion. Instead, it lists various bench tests performed and makes a general statement about meeting predetermined criteria and equivalence to the predicate device.

Acceptance Criteria (Implied / General Statement)	Reported Device Performance
Spatial resolution (MTF)	Met pre-defined criteria; equivalent to predicate.
Pixel defects/faults (maximum number allowed)	Met pre-defined criteria; equivalent to predicate.
Absence of miscellaneous artifacts (TG18 guideline)	Met pre-defined criteria; equivalent to predicate.
Temporal response	Met pre-defined criteria; equivalent to predicate.
Luminance	Met pre-defined criteria; equivalent to predicate.
Conformance to DICOM GSDF (TG18 guideline)	Met pre-defined criteria; equivalent to predicate.
Angular dependency of luminance response	Met pre-defined criteria; equivalent to predicate.
Luminance non-uniformity (TG18 guideline)	Met pre-defined criteria; equivalent to predicate.
Chromaticity non-uniformity (TG18 guideline)	Met pre-defined criteria; equivalent to predicate.
Luminance stability	Met pre-defined criteria; equivalent to predicate.
Noise (NPS)	Met pre-defined criteria; equivalent to predicate.
Display reflections (specular, diffuse, haze)	Met pre-defined criteria; equivalent to predicate.
Small-spot contrast ratio	Met pre-defined criteria; equivalent to predicate.
Pixel aperture ratio	Met pre-defined criteria; equivalent to predicate.
Color tracking and Gray tracking	Met pre-defined criteria; equivalent to predicate.

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

Sample Size for Test Set: Not applicable. This document describes bench testing of a hardware device (display monitor), not a study involving patient data or images. The "test set" would refer to the physical display units tested.
Data Provenance: Not applicable in the context of imaging data. The tests were performed according to "Guidance for Industry and FDA Staff: Display Devices for Diagnostic Radiology" and AAPM Task Group 18 (TG18 guideline).

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

Not applicable. Ground truth, in this context, would relate to the accuracy of diagnostic interpretations by a human or AI system. This document concerns the performance characteristics of a display monitor as a tool, not its diagnostic output. Its performance is measured against established physical and photometric standards.

4. Adjudication method for the test set

Not applicable. Adjudication methods are relevant for resolving discrepancies in expert interpretations of medical images, which is not the subject of this document.

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. This document does not mention any MRMC comparative effectiveness study, nor does it discuss AI assistance. The subject is a medical display monitor.

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

No. This document does not describe any algorithm or AI system, standalone or otherwise.

7. The type of ground truth used

For the bench tests, the "ground truth" is established by physical standards and technical specifications for display performance, such as:

TG18 guideline (AAPM Task Group 18)
DICOM GSDF (Grayscale Standard Display Function)
Manufacturer's internal specifications and design targets for parameters like resolution, luminance, contrast ratio, etc.

8. The sample size for the training set

Not applicable. This is not an AI/machine learning device; therefore, there is no "training set."

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

Not applicable. As there is no training set for an AI model, there is no ground truth established for it.

4. Device Description

Image /page/4/Picture/2 description: The image shows two medical monitors displaying different types of medical scans. The monitor on the left displays a series of CT scans of the chest and lungs, including cross-sectional views and 3D reconstructions. The monitor on the right shows a mammogram on the left screen and ultrasound images of the breast on the right screen. The images suggest the use of advanced medical imaging technologies for diagnostic purposes.

RX1270 (12MP)

RX560 (5MP) x 2

Since factory calibrated display modes, each of which is characterized by a specific tone curve (including DICOM GSDF), a specific luminance range and a specific color temperature, are stored in lookup tables within the monitor, the tone curve is e.g. DICOM compliant regardless of the display controller used.

There are two model variations, RX1270 and RX1270-AR. The difference of the two variations is the surface treatment of the display screens; the surface treatment of the RX1270 is Anti-Glare (AG) treatment and that of the RX1270-AR is Anti-Reflection (AR) coating.

RadiCS is application software to be installed in each workstation offering worry-free quality control of the diagnostic monitors including the RadiForce RX1270 based on the OC standards and guidelines and is capable of quantitative tests and visual tests defined by them. The RadiCS and its subset, RadiCS LE, are included in this 510(k) submission as an accessory to the RadiForce RX1270.

. Measurement of small-spot contrast ratio
Measurement of pixel aperture ratio ●
Measurement of Color tracking and Gray tracking

The test results showed that the RadiForce RX1270 has display characteristics equivalent to those of the predicate device, RadiForce RX560.

Besides, the display characteristics of the RadiForce RX1270 meet the pre-defined criteria when criteria are set.

No animal or clinical testing was performed on the RadiForce RX1270.

8. Conclusion

The RadiForce RX1270 was determined to be substantially equivalent to the predicate device due to the following reasons:

. The stated intended use is substantially the same as that of the predicate device.
. It was confirmed that the technological characteristics differences from those of the predicate device do not affect the safety or the effectiveness.
The bench tests demonstrated that the display characteristics are equivalent to those of . the predicate device.
