Device Story

RadiForce GX540 is a 5MP monochrome LCD monitor using IPS technology for medical image display, including mammography. It receives digital video signals via DVI-D or DisplayPort. The device features factory-calibrated display modes stored in internal lookup tables to ensure DICOM GSDF compliance regardless of the display controller. It includes integrated sensors (backlight, front, presence, ambient light) for quality control. RadiCS application software, installed on a workstation, manages quality control, performing quantitative and visual tests. Used in clinical settings by medical practitioners for image review and analysis; output facilitates diagnostic decision-making. Benefits include high-resolution, calibrated visualization of medical images.

Clinical Evidence

No clinical or animal testing was performed. Evidence is based on bench testing, including conformance to AAPM TG18 guidelines for medical imaging displays. Tests included luminance response, chromaticity, spatial resolution (MTF), noise power spectrum (NPS), temporal response, and luminance stability. All results were consistent with expected performance.

Regulatory Classification

Identification

A medical image management and processing system is a device that provides one or more capabilities relating to the review and digital processing of medical images for the purposes of interpretation by a trained practitioner of disease detection, diagnosis, or patient management. The software components may provide advanced or complex image processing functions for image manipulation, enhancement, or quantification that are intended for use in the interpretation and analysis of medical images. Advanced image manipulation functions may include image segmentation, multimodality image registration, or 3D visualization. Complex quantitative functions may include semi-automated measurements or time-series measurements.

## 6. Device Description

RadiForce GX540 is a monochrome LCD monitor for viewing medical images including those of mammography. The monochrome panel employs in-plane switching (IPS) technology allowing wide viewing angles and the matrix size (or resolution) is 2,048 x 2,560 pixels (5MP) with a pixel pitch of 0.165 mm.

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.

Model variations with cosmetic differences are distinguished by characters attached to the name of the base model "GX540" such as "GX540-CLAR", a model whose backlight is Clear Base with an Anti-Reflective coating on the screen surface although the hardware design, components and labeling remain unchanged.

RadiCS is application software to be installed in each workstation offering worry-free quality control of the diagnostic monitors including the RadiForce GX540 based on the QC standards and guidelines and is capable of quantitative tests and visual tests defined by them. The RadiCS is included in this 510(k) submission as an accessory to the RadiForce GX540.

## 7. Intended Use

This product is intended to be used in displaying digital images including those of digital mammography for review and analysis by trained medical practitioners.
