Intended Use

The RadiForce RX840-MG is intended to be used in displaying and viewing digital images including those of digital mammography for review and analysis by trained medical practitioners.

Device Story

RadiForce RX840-MG is an 8MP color LCD monitor designed for medical imaging, including digital mammography. It utilizes an IPS color panel with LED backlighting to display high-resolution images (4096 x 2160). The device functions as a replacement for traditional dual-head 5MP monochrome monitor setups. It incorporates factory-calibrated display modes stored in internal lookup tables to ensure DICOM GSDF compliance regardless of the connected workstation or display controller. The monitor includes integrated sensors (backlight, front, presence, and ambient light) for quality control. It is used in clinical environments by trained medical practitioners to review and analyze diagnostic images. The device is supported by RadiCS application software for quality control management. By providing a high-resolution, color-capable display, it enables clinicians to view complex medical imagery, facilitating accurate diagnostic decision-making.

Clinical Evidence

No clinical or animal testing was performed. Substantial equivalence was established through bench testing following AAPM TG18 guidelines. Tests included DICOM GSDF conformance, angular luminance dependency, luminance/chromaticity non-uniformity, reflection measurements, contrast ratio, MTF, noise power spectrum (NPS), pixel aperture ratio, temporal response, and luminance stability.

#### 6. Device Description

The RadiForce RX840-MG 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. With the matrix size (or resolution) of 4.096 x 2.160 pixels (8MP), the RX840-MG is an alternate replacement for traditional dual head 5MP display installations.

Image /page/1/Picture/2 description: The image shows two different medical monitors. The monitor on the left is a RadiForce RX360-MG, and the two monitors on the right are 5MP monitors. All three monitors are displaying medical images. The monitors are all black and have a thin bezel.

RadiForce RX840-MG

5MP Monochrome Monitors

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. This helps ensure tone curves even if a display controller or workstation must be replaced or serviced.

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

#### 7. Intended Use

The RadiForce RX840-MG is intended to be used in displaying and viewing digital images including those of digital mammography for review and analysis by trained medical practitioners.

{4}------------------------------------------------

For the substantial equivalence determination, only the following differences of the technological characteristics need further evidences by performance testing:

- ' The RadiForce RX840-MG employs a color LCD panel module though the predicate device employs a monochrome LCD panel module.
- . The smaller number of gray tones available to calibration of the color display (e.g. to GSDF) than that of the monochrome display may affect calibration accuracy.
- -The RadiForce RX840-MG employs an LED backlight though the predicate device employs a CCFL backlight; advantage of the LED backlight is that it is mercury-free, consumes less power and deteriorates more slowly.

# 9. Performance Testing

The following bench tests were performed on the RadiForce RX840-MG following instructions in Guidance for Industry and FDA Staff: Display Accessories for Full-Field Digital Mammography Systems-Premarket Notification (510(k)) Submissions:

- Verification of the conformance to DICOM GSDF as specified in Assessment of . Display Performance for Medical Imaging Systems by AAPM Task Group 18 (TG18 guideline)
- Measurement of the angular dependency of luminance response in horizontal, . vertical and diagonal directions
- . Measurement of the luminance non-uniformity characteristics of the display screen as specified in TG18 guideline
- . Measurement of the chromaticity non-uniformity characteristics of the display screen as specified in TG18 guideline
- Measurement of the chromaticity at the center of the display screen at 5%, 50% and . 95% of the maximum luminance
- Measurement of display reflections including specular, diffuse and haze components .
- Measurement of small-spot contrast ratio .
- Measurement of spatial resolution expressed as modulation transfer function (MTF) .
- Measurement of noise expressed as noise power spectrum (NPS) ●
- . Measurement of pixel aperture ratio
- Visual check of presence or absence of miscellaneous artifacts on the display screen . as specified in TG18 guideline
- Measurement of temporal response .
- Performance data on luminance stability .
- The maximum number allowed for each type of pixel defects/faults agreed with the . manufacturer from which Eizo buys the LCD panels for RadiForce RX840-MG

{5}------------------------------------------------

The test results showed that the RadiForce RX840-MG has display characteristics equivalent to those of the predicate device, RadiForce GX530 except 4 items, each of which was determined that it would not affect observer's performance. Besides, the display characteristics of the RadiForce RX840-MG meet the pre-defined criteria when criteria are set.

No animal or clinical testing was performed on the RadiForce RX840-MG.

#### 10. Conclusion

The 8MP Color LCD Monitor, RadiForce RX840-MG to be used in dual-head configuration has the same intended use as the predicate device but some different technological characteristics. Bench testing showed that the safety and effectiveness of the RadiForce RX840-MG was not affected by the differences of the technological characteristics. Therefore, the RadiForce RX840-MG was determined to be substantially equivalent to the predicate device.
