K050667 is an FDA 510(k) clearance for the R2 FAMILY OF IMAGE DISPLAY UNITS WITH R2 UNIFORM DISPLAY SOFTWARE. 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 R2 Technology, Inc. (Sunnyvale, US). The FDA issued a Cleared decision on March 29, 2005 after a review of 14 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. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: Incremental AI imaging tool. Moderate equivalence dependency. 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.
