Device Story

The CCL550i2 is a 21.3-inch color LCD monitor designed for displaying high-resolution medical images, specifically for digital mammography and FFDM. It receives image data via DVI or DisplayPort from a PACS or imaging modality. The device features an LED-backlit panel and internal 16-bit LUTs to ensure compliance with the DICOM GSDF for grayscale rendering. It includes a front sensor and ambient light sensor to automate luminance stabilization and grayscale calibration, reducing the need for manual intervention. The monitor is used in clinical settings by radiologists and medical practitioners to view diagnostic images. The output is a high-fidelity visual representation of medical data, which supports clinical decision-making by providing consistent, calibrated image quality. The device benefits patients by ensuring accurate, reliable visualization of mammographic images for diagnostic assessment.

Clinical Evidence

Bench testing only. Performance was validated through system and integration testing, including luminance response, uniformity, geometrical distortion, veiling glare, chromaticity, and temporal response. Calibration accuracy using the integrated front sensor was verified against external sensors. Compliance with AAPM-TG18 guidelines and international safety/EMC standards was confirmed.

Technological Characteristics

21.3-inch AMLCD panel; LED backlight; 2048x2560 resolution; 10-bit per pixel intrinsic depth; 16-bit LUT; DVI and DisplayPort connectivity; integrated front sensor and ambient light sensor for calibration; power supply 100-240V AC. Complies with ANSI/AAMI ES60601-1 and CAN/CSA-C22.2 No. 601-1.

Indications for Use

Indicated for trained medical practitioners to display and view medical images for diagnosis in digital mammography PACS and modalities including FFDM.

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.

Dear Mr. Tashiro:

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.

# bstantial Equivalence Compariso

Similarities

Similarities:
CCL55012 (CL21550) employs the same driver board, tilt stand, power supply, etc. except of those of LCD Panel and standard software

Differences:
CCL550i2 (CL21550) employs different LCD panel and standard softwar

{7}------------------------------------------------

CCL550i2 (CL21550) can be considered to have equivalent display performances to those of the predicate device MS55i2 (ML21055) due to the following reasons:

- a. The maximum display sizes (2048*2560) and the active area sizes (337.92mm (H) x 422.4mm (V)) used for the both devices are the same.
- b. The DICOM calibrated luminance value of the both devices are the same (500 cd/m²) though the typical maximum luminance value (typ. 1000cd/m²) is lower than that of the predicate device (typ. 1200cd/m²). And Panels of the both devices are used LED backlight. The high luminance to be maintained constantly was realized by the employment of LED backlight deteriorating more slowly than conventional CCFL backlights. We have not recognized any adverse effects of the LED backlight on the quality of displayed images. Refer to "Technical Data" where several image quality characteristics of the proposed device are compared with those of the predicate device.
- c. The both devices display images in accordance with DICOM GSDF by default utilizing the factory calibrated display mode stored in lookup tables inside of them.
- d. Both devices support Digital Visual Interface (DVI) and DisplayPort.
- e. As for the maintenance, the same QC software is used for both devices have Front Sensor to stabilize the luminance.
- f. As for built-in sensors, both devices have 2 (two) kinds of common sensors, Front Sensor and Ambient Light Sensor. Front Sensor is related to the maintenance or calibration and Ambient Light Sensor is used to measure the ambient light by lx. Front sensor enables automatic grayscale calibration by measuring the luminance at the screen surface. Without Front sensor, the grayscale calibration process requires human intervention and the use of and external sensor. The accuracy data of the calibration with external sensors and that with Front Sensor is included in section 8 "Validation & Verification: Integration Test Report" and section 9 "Validation & Verification: System Test Report" in "Application".
- g. The overall design of the CCL550i2 (CL21550) was validated in accordance with internationally recognized Safety and EMC standards by third-party certifiers. Besides, JVC KENWOOD Corporation performed a range of system and performance tests to ensure that the CCL550i2 (CL21550) performs in accordance with its specifications. None of the tests revealed behaviors inconsistent with the expected performance.

### Conclusion

The 5M pixel Color LCD Monitor, CCL550i2 (CL21550) is substantially equivalent to the predicate device with respect to technical characteristics, application and intended use. The specifications of the primary components employed by the proposed device are the same to those of the predicate device except for the LCD panel, and the differences have been independently validated. Any differences between the devices do not affect safety or effectiveness.
