21.3 INCH MONOCHROME DIGITAL MAMMOGRAPHY LCD MONITOR MS55I2 (ML21055, MD211G5)
21.3 inch Monochrome Digital Mammography 5M pixel LCD Monitor with sub-pixel driving techniques enabling 15M subpixels to be driven independently, MS55i2 (ML21055, MD211G5) is intended to be used in displaying and viewing medical images for diagnosis by trained medical practitioners. It is to be used in digital mammography PACS and modalities including FFDM.
MS55i2 (ML21055, MD211G5) is a 21.3-inch monochrome LCD monitor whose display resolution is 2048 x 2560 (landscape), 2560 x 2048 (portrait) supporting DVI (digital visual interface) and DisplayPort.
Here's an analysis of the provided text regarding the acceptance criteria and study for the JVCKENWOOD MS55i2 monitor.
The document describes a 510(k) premarket notification for a medical display monitor. The "study" in this context refers to product verification and validation testing to ensure the monitor meets specified technical performance criteria, rather than a clinical study involving human readers or patient outcomes, as is common for AI-powered diagnostic devices.
Here's the requested information:
