K080422 is an FDA 510(k) clearance for the 5 MEGAPIXEL MONOCHROME LCD MONITOR, MODEL RADIFORCE GS520. Classified as System, Image Processing, Radiological within the LLZ classification (a category encompassing advanced image processing and PACS-adjacent software), Class II - Special Controls.

Submitted by Eizo Nanao Corporation (Hakusan, Ishikawa-Ken, JP). The FDA issued a Cleared decision on March 10, 2008 after a review of 24 days - a notably fast clearance cycle.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.2050 - the FDA radiology and imaging software oversight framework. As a Special 510(k), this submission covers a manufacturer modification to an existing cleared device rather than a new device introduction.

Device pattern: Incremental AI imaging tool. Low regulatory complexity profile. Overall, this clearance reflects a predicate-aligned approval typical of modern AI radiology extensions - not a novel clinical breakthrough, but a validated iteration within an established regulatory category.
