K033577 is an FDA 510(k) clearance for the UNISCAN, PULMOSCAN, PULMOSCAN RADIOGRAPHIC SYSTEMS. Classified as System, X-ray, Stationary (product code KPR), Class II - Special Controls.

Submitted by Medlink Imaging (Deer Field, US). The FDA issued a Cleared decision on March 18, 2005 after a review of 491 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1680 - the FDA radiology and imaging software oversight framework. The Abbreviated 510(k) pathway was used, relying on FDA-recognized standards to demonstrate substantial equivalence.

Device pattern: High-complexity regulatory submission. Standards-verified equivalence. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind Radiology submissions.
