K926019 is an FDA 510(k) clearance for the FORARM OPT/NORLAND XR SERIES X-RAY BONE DENSITOMET. Classified as Densitometer, Bone (product code KGI), Class II - Special Controls.

Submitted by Norland Corp. (Fort Atkinson, US). The FDA issued a Cleared decision on September 23, 1994 after a review of 662 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.1170 - 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: High-complexity regulatory submission. Elevated predicate reliance profile. 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.
