Intended Use

JUSHA-C33C LCD Monitor 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.

Device Story

JUSHA-C33C is a 21.3" color TFT LCD diagnostic monitor; inputs digital image signals via DVI or DisplayPort; processes signals using Color/Gray Automatic (CGA) function to identify signal type and apply appropriate Look-Up Tables (DICOM for gray, GAMMA 2.2 for color); features ambient brightness adaptation and presence induction for automatic display adjustment; outputs high-resolution (2048x1536) images for clinical diagnosis; used by radiologists/physicians in clinical settings; assists in diagnostic decision-making by providing calibrated, high-luminance (600 cd/m²) visualization of medical images.

Clinical Evidence

No clinical data; substantial equivalence supported by bench testing, including risk analysis, design reviews, module/system verification, and final validation testing.

Technological Characteristics

21.3" Color TFT LCD panel; 2048x1536 resolution; 600 cd/m² luminance; 12-bit color expansion; 8 DICOM LUTs and 3 GAMMA LUTs; ambient brightness/presence sensors; DVI/DisplayPort connectivity; LED backlight; complies with IEC 60601-1 and IEC 60601-1-2.

Indications for Use

Indicated for trained medical practitioners to display and view digital images for diagnosis of X-ray or MRI. Not indicated for mammography image display.

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).

Predicate Devices

• EIZO RX340 (K113562)

Dear Ms. Le:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug. and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
