Device Information - Trade Name/Model: RadiForce RX340 . - 3MP Color LCD Monitor Common Name: . - System, Image Processing, Radiological Classification Name: . - Classification Number: 21 CFR 892.2050. Product Code LLZ � #### 5. Predicate Device - Color LCD Monitor, RadiForce RX320 (K090045) . ## 6. Device Description The RadiForce RX340 is a color LCD monitor for viewing medical images other than those of mammography. The matrix size (or resolution) of the panel is 1,536 x 2,048 pixels (3MP) with a pixel pitch of 0.21075 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. ಗ Section 05 {1}------------------------------------------------ Model variations with cosmetic differences are distinguished by characters attached to the name of the base model "RX340" such as "RX340-AR", a model with an Anti-Reflective coating 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 RX340 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 RX340. ## 7. Intended Use The RadiForce RX340 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 RX340 can be said to have at least the same display performances as those of the predicate device by default due to the following reasons: - The matrix sizes (1536 x 2048) and the active area sizes (323.7 mm x 431.6 mm) of a. the LCD panels used by the both devices are the same. - The DICOM calibrated luminance values of the both devices are the same (400 b. cd/m²) though the typical maximum luminance values (1000 cd/m²) is higher than that of the predicate device (900 cd/m2). The higher luminance to be maintained constantly was realized by the employment of LED backlight deteriorating more slowly than conventional CCFL backlights. - The LED backlight was newly employed instead of CCFL backlight because it is C. 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 d. 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 e. supported by the predicate device, RadiForce RX340 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. 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, RX340 has three kinds of sensors. However, only the Built-in Front Sensor (IFS) has something to do with the {2}------------------------------------------------ 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 RX340 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 RX340 performs in accordance with its specifications. None of the tests revealed behaviors inconsistent with the expected performance. #### 9. Conclusion The 3MP Color LCD Monitor, RadiForce RX340 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 the same to those of the predicate device and other differences have been independently validated. Any differences between the devices do not affect safety or effectiveness. {3}------------------------------------------------ Image /page/3/Picture/0 description: The image shows the logo for the U.S. Department of Health & Human Services.
