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).

First time submission to market this LCD Monitor as Medical Device in the USA.

#### E-10. Description of Marketed Device

Device Name : Barco Coronis 3MP Medical Flat Panel Display System

510(k) number : K013922

Intended use :

The Barco Coronis 3MP Medical Flat Panel Display System is intended to be used in displaying and viewing digital images for review by trained medical practitioners.

#### Device description :

The monitor combines a TFT(thin film transistor) liquid crystal display panel structure and a built-in backlight with inverter for a better picture quality.

The monitor can be used in portrait or landscape version, simply by turning the panel.

The tilt and swivel foot allows ideal positioning of the panel, in height and viewing angle.

The image brightness can be adjusted by means of a control wheel on the monitor.

The 21.3inch Monochrome LCD Monitor has the same intended use, technical characteristics and performance as the legally marketed device (K013922) and thus Substantial Equivalence is given.

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

E-11. Substantial Equivalence Comparison

Device Description :

The LCD panel adopts Super Advanced-Super Fine TFT(SA-SFT) for the MD21GS-3MP-CB, BB and MD211GS3P-CB, BB.

Additionally, a low reflection overooat is applied on top of the bead layer, which yields a low, uniform reflection over the surface of the glass.

This process also provides for a truer representation of black and a higher contrast ratio.

The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB can select the use of the landscape or the portrait only by rotating the LCD panel.

The tilt and swivel foot allows ideal positioning of the panel, in height and viewing angle.

In addition, because our device has the height adjustment function of the stand, a more ideal positioning can be offered.

Please refer to "Table E-11".

#### Intended Use :

The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB are intended to be used for displaying and viewing of digital images for diagnosis by trained physicians.

These gray scale display must not be used for primary diagnostic in mammography.

Barco Coronis 3MP is intended to be used in displaying and viewing digital images for review by trained medical practitioners.

It is intended to be used to support the diagnosis to either device.

Technical Characteristics and performance :

The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB can select the use of 2048*1536 of the landscape modes or the portrait modes of 1536*2048 only by rotating the panel equally to the legally marketed device.

Barco Coronis 3MP has the viewing angle of 170°,

The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB greatly decreases the shift of the Gamma characteristic by the view corner by the wide viewing angle of 176° by the adoption of the latest SA-SFT panel.

The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB provides support for improved diagnostic accuracy with simultaneous reproduction of up to 1024 from a palette of 3061 possible grayscales.

The 10-bit gamma correction ensures precise and smooth grayscale tuning and better representation of just noticeable difference.

Up to 1024 grayscales can be depicted at the same time for film-less diagnosis.

{3}------------------------------------------------

The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB are different in the following points compared with the legally marketed device.

Barco Coronis 3MP in difference of built-in circuit of power supply instead of AC adapter.

In Barco Coronis 3MP, the AC voltage converts into the DC voltage with the AC adaptor and is supplied to the device.

In The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB, the AC voltage converts into the DC voltage in the device.

Therefore, the monitor is operated by the dc voltage, and is substantial equivalent to the legally marketed device.

The Barco Coronis 3MP has the insulation structure which meets the standard of UL60950.

However, The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB has the insulation structure which meets the standard of UL60601.

The MD21GS-3MP-CB, BB and MD211GS3P-OB, BB are applied a severer safety standard compared with the legally marketed device.

Therefore, our monitor safety is more excellent than the legally marketed device.

Therefore, The MD21GS-3MP-CB, BB and MD211GS3P-CB, BB are device with higher safety compared with the legally marketed device.
