K180671 is an FDA 510(k) clearance for the MINE. Classified as Unit, X-ray, Extraoral With Timer (product code EHD), Class II - Special Controls.

Submitted by Rht Co., Ltd. (Gwangju, KR). The FDA issued a Cleared decision on June 5, 2019 after a review of 448 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the Radiology FDA review panel, regulated under 21 CFR 872.1800 - 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.
