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

• Color LCD Monitor, FlexScan MX300W (K073340)

### 6. Device Description

The RadiForce RX840 is a color LCD monitor for viewing medical images other than those of mammography. The matrix size (or resolution) of the panel is 4096 x 2160 pixels (8MP), spacious enough to display e.g. two 3MP radiological images and other clinical information side by side without obtrusive bezels.

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.

{1}------------------------------------------------

Model variations with cosmetic differences are distinguished by characters attached to the name of the base model "RX840" such as "RX840-AR", a model with an Anti-Reflective coating.

RadiCS is application software to be installed in each workstation offering worry-free quality control of the diagnostic monitors including RX840 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 RX840.

## 7. Intended Use

The RadiForce RX840 is intended to be used in displaying and viewing digital images for diagnosis of X-ray or MRI, etc. by trained medical practitioners. The device does not support the display of mammography images for diagnosis.

## 8. Technological Characteristics

The RadiForce RX840 can be said to have at least the same display performances as those of the predicate device by default due to the following reasons:

- Both the matrix size and the active area size of the LCD panel used (4,096 x 2,160, a. 817.1 mm x 430.9 mm) are larger than those of the predicate device (2,560 x 1,600, 641.3 mm x 400.8 mm).
- The smaller pixel pitch or pixel size (0.1995 x 0.1995 mm) than that of the predicate b. device (0.2505 x 0.2505 mm) means higher density usually resulting in higher quality of displayed images. If one cares about the smaller pixel size, the perceived pixel size similar to that of the predicate device can be realized easily by adjusting the viewing distance.
- The DICOM calibrated luminance (400 cd/m²) and the typical maximum luminance C. (700 cd/m2) is higher than that of the predicate device (170 cd/m², 300 cd/m²). The higher luminance to be maintained constantly was realized by the employment of LED backlight deteriorating more slowly than conventional CCFL backlights.
- d. The LED backlight was newly employed instead of CCFL backlight because it is mercury-free, consumes less power and deteriorates more slowly. We have not recognized any adverse effects of the LED backlight on the quality of displayed images. Refer to section 18 "Performance Testing - Bench" where several image quality characteristics of the proposed device are compared with those of the predicate device.
- The both devices display images in accordance with DICOM GSDF by default e. utilizing the factory calibrated display mode stored in lookup tables inside of them.
- As for input video signal, in addition to the Digital Visual Interface (DVI) also f. supported by the predicate device, RadiForce RX840 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 quality of displayed images.

{2}------------------------------------------------

As for the maintenance, the same QC 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, RX840 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 (PS) detects the absence of the user to trigger the power saving mode of the monitor and the Ambient Light Sensor (ALS) is used to measure the ambient light by lx. The IFS enables automatic grayscale calibration 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 accuracy data of the calibration with external sensors and that with the IFS is included in section 16.9 "Verification and Validation Documentation".

The overall design of the RadiForce RX840 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 RX840 performs in accordance with its specifications. None of the tests revealed behaviors inconsistent with the expected performance.

## 9. Conclusion

The 8MP color LCD monitor, RadiForce RX840 is substantially equivalent to the predicate device with respect to technical characteristics, application and intended use. The specifications of the primary component employed by the proposed device are superior to those of the predicate device and other differences have been independently validated. Any differences between the devices do not affect safety or effectiveness.
