K905488 is an FDA 510(k) clearance for the DOPPLER UPGRADE FOR AUSONICS OPUS 1 REAL TIME SCAN. Classified as Device, Digital Image Storage, Radiological (product code LMB), Class I - General Controls.

Submitted by Ausonics Pty , Ltd. (Washington, US). The FDA issued a Cleared decision on December 18, 1991 after a review of 376 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 892.2010 - 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: Standard predicate-based submission. Elevated predicate reliance profile. This clearance follows a standard predicate-based equivalence path within the Radiology review framework, consistent with the majority of Class II 510(k) submissions.
