Intended Use

This product is intended to be used in displaying 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 MX315W is a 31.1-inch color TFT IPS LCD monitor; 8MP resolution (4,096 x 2,160); LED backlighting. Used in clinical settings by trained medical practitioners for viewing/analyzing medical images (excluding mammography). Device receives digital video signals via DVI-D or DisplayPort; internal lookup tables apply factory-calibrated tone curves (DICOM GSDF compliant) to ensure accurate luminance and color reproduction. Digital Uniformity Equalizer compensates for luminance non-uniformity. Integrated sensors (backlight, front, presence, ambient light) support quality control. RadiCS application software installed on workstations performs quantitative and visual QC tests. Output is a high-resolution visual display of medical images, aiding clinicians in diagnostic decision-making.

Clinical Evidence

Bench testing only. Conformance to DICOM GSDF, luminance/chromaticity non-uniformity, MTF spatial resolution, and pixel defect testing performed per AAPM TG18 guidelines. No clinical or animal testing performed.

Technological Characteristics

TFT Color LCD Panel (IPS); 8MP (4,096 x 2,160) resolution; LED backlight; 1300:1 contrast ratio; 450 cd/m2 max luminance. Connectivity: DVI-D, DisplayPort. Integrated sensors: backlight, front, presence, ambient light. Software: RadiCS for QC. Digital Uniformity Equalizer. Power: 100-240V AC.

Indications for Use

Indicated for trained medical practitioners to display and view digital images for review, analysis, and diagnosis. Excludes mammography images.

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.

# 6. Device Description

RadiForce MX315W 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 4,096 x 2,160 pixels (8MP) with a pixel pitch of 0.1704 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.

RadiCS is application software to be installed in each workstation offering worry-free quality control of the diagnostic monitors including the RadiForce MX315W 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 MX315W.

## 7. Indications for 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 MX315W.

- 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 MX315W has display characteristics equivalent to those of the predicate device, RadiForce RX840.

Besides, the display characteristics of the RadiForce MX315W meet the pre-defined criteria when criteria are set.

No animal or clinical testing was performed on the RadiForce MX315W.

### 10. Conclusion

The RadiForce MX315W 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 differences from those of the predicate device do not affect the safety or the effectiveness.
- . The bench tests demonstrated that the display characteristics are equivalent to those of the predicate device.
