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.

Special Controls

*Classification.* Class II (special controls; voluntary standards—Digital Imaging and Communications in Medicine (DICOM) Std., Joint Photographic Experts Group (JPEG) Std., Society of Motion Picture and Television Engineers (SMPTE) Test Pattern).

Predicate Devices

• RadiForce GS510 (K062054)

#### 5. Predicate Device

5MP Monochrome LCD Monitor, RadiForce GS510 (K062054)

#### 6. Device Description

The RadiForce GX530 is a 5MP monochrome LCD monitor for viewing medical images including those of digital mammography. The monochrome panel employs in-plane switching (IPS) technology allowing wide viewing angles. The matrix size (or resolution) of the panel is 2560 x 2048 pixel pitch is 0.165 mm, both of which are the same as those of displays approved so far for digital mammography including the predicate device, RadiForce GS10. Since factory calibrated display modes, each of which is characterized by a specific tone curve (including DICOM GSDF) and a specific luminance range, are stored in lookup tables within the monitor, the tone curve is e.g. DICOM compliant regardless of the display controller used.

RadiCS is application software to be installed in each workstation offering worry-free quality control of the diagnostic monitors including GX530 based on several QC guidelines. The RadiCS and its subset, RadiCS LE are included in this 510(k) submission as an accessory to the RadiForce GX530.

### 7. Intended Use

The RadiForce GX530 is intended to be used in displaying digital images including those of digital mammography for review and analysis by trained medical practitioners.

#### 8. Technological Characteristics

RadiForce GX530 can be said to have at least the same display performance as those of the predicate device by default due to the following reasons:

- · The matrix sizes (2048 x 2560) and the active area sizes (337.9 mm x 422.4 mm) of the LCD panels used by . the both devices are the same though they are from different manufacturers.
- The both devices display images in accordance with DICOM GSDF by default utilizing the factory calibrated . display mode stored in one of the lookup tables inside of them.
- . As for input video signal, in addition to the Digital Visual Interface (DVI) also supported by the predicate device, RadiForce GX530 supports DisplayPort, another type of digital video interface based on an industrial standard. As far as the both the DVI and the DisplayPort are digital, their differences do not affect the image quality.

As for the maintenance, the same OC software is used for the both devices and the implementation of the Backlight Sensor (BS) stabilizing the backlight is also the same.

As for built-in sensors, in addition to BS common to the both devices, GX530 has three kinds of sensors. However, only the Built-in Front Sensor (IFS) has something to do with the maintenance or the calibration; the Presence Sensor detects the absence of the user to trigger the power saving mode of the Ambient Light Sensor is used to measure the ambient light by Ix. The IFS enables automatic grayscale callbration by measuring the luminance at the screen surface. Without IFS, the grayscale calibration process requires human intervention and the use of an external sensor. The precision data of the callbration with an external sensor and with the IFS is provided as one of the validation data.

The overall design of the RadiForce GX530 was validated in accordance with internationally recognized safety and EMC standards by independent testing facilities and in-house ones. Besides, EIZO NANAO CORPORATION performed a range of system and performance tests to ensure that the RadiForce GX530 performs in accordance with its specifications. None of the tests revealed behaviors inconsistent with the expected performance.

#### 9. Conclusion

Section-05

5MP Monochrome LCD Monitor, RadiForce GX530 is substantially equivalent to the predicate device with respect to technical characteristics, application and intended use. The primary components are the same and those that are different have been independently validated. Any differences between the devices do not affect safety or effectiveness.

The 510(k) Premarket Notification for the RadiForce GX530 contains sufficient information and data to enable FDA -CDRH to determine substantial equivalence to the predicate device.
