Intended Use

This product is intended to be used in displaying and viewing digital images for review, analysis and diagnosis by trained medical practitioners. It does not support the display of mammography images for diagnosis.

Device Story

RadiForce RX350 is a 3MP (1,536 x 2,048) color IPS LCD monitor for medical imaging. It receives video signals via DVI-D or DisplayPort; internal lookup tables ensure DICOM GSDF compliance regardless of the display controller. The device features integrated sensors (backlight, presence, front, ambient light) for automated quality control. It is used in clinical environments by medical practitioners to view diagnostic images. RadiCS software, included as an accessory, performs quantitative and visual quality control tests. The monitor provides high-resolution, color-accurate visualization to support clinical decision-making and diagnostic review.

Clinical Evidence

No clinical or animal testing was performed. Substantial equivalence is supported by bench testing, including verification of DICOM GSDF conformance, luminance and chromaticity non-uniformity measurements, MTF spatial resolution testing, and pixel defect analysis per AAPM TG18 guidelines.

Technological Characteristics

3MP (1,536 x 2,048) color IPS LCD monitor; LED backlighting; 1,000 cd/m² max luminance; 1500:1 contrast ratio. Connectivity: DVI-D, DisplayPort (with daisy chain). Integrated sensors: backlight, presence, front, ambient light. Includes RadiCS software for QC. Digital Uniformity Equalizer for luminance compensation. 10-bit input support.

Indications for Use

Indicated for trained medical practitioners to display and view digital images for review, analysis, and diagnosis. Not indicated for the display of mammography images.

Regulatory Classification

## 6. Device Description

RadiForce RX350 is a color LCD monitor for viewing medical images other than those of mammography. The color panel employs in-plane switching (IPS) technology allowing wide viewing angles and the matrix size (or resolution) is 1,536 x 2,048 pixels (3MP).

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 "RX350" such as "RX350-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 the RadiForce RX350 based on the QC standards and guidelines and is capable of quantitative tests and visual tests defined by them. The RadiCS and its subset, RadiCS LE, are included in this 510(k) submission as an accessory to the RadiForce RX350.

#### 7. Intended Use

This product is intended to be used in displaying and viewing digital images for review, analysis and diagnosis by trained medical practitioners. It does not support the display of mammography images for diagnosis.

## 9. Performance Testing

The following bench tests were performed on the RadiForce RX350.

- . 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 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
- . Visual check of presence or absence of miscellaneous artifacts on the display screen as specified in TG18 guideline
- Measurement of spatial resolution expressed as modulation transfer function (MTF)
- . The maximum number allowed for each type of pixel defects/faults

The test results showed that the RadiForce RX350 has display characteristics equivalent to those of the predicate device. RadiForce RX340 except one item, which was determined that it would not affect observer's performance.

Besides, the display characteristics of the RadiForce RX350 meet the pre-defined criteria when criteria are set.

No animal or clinical testing was performed on the RadiForce RX350.

#### 10. Conclusion

The RadiForce RX350 was determined to be substantially equivalent to the predicate device due to the following reasons:

- The stated intended use is substantially the same as that of the predicate device.
- . It was confirmed that the technological characteristics different from those of the predicate device do not affect the safety and the effectiveness.
- . The bench tests demonstrated that the display characteristics are equivalent to those of the predicate device except one item, which was determined that it would not affect observer's performance.
