OPTOS PLC Volumetric OCT Image Data Processing Patent Granted
Summary
The USPTO granted Patent US12599302B2 to OPTOS PLC on April 14, 2026, covering a method of processing volumetric C-scan OCT image data. The patent claims a technique for compensating axial displacements between B-scans caused by relative motion during OCT acquisition, using indicators of axial shift between adjacent B-scans to determine a first frequency component indicative of motion. The patent names inventors Praveen Ashok and Alan Anderson and contains 24 claims.
“A method of processing C-scan data, which comprises a sequence of B-scans of an imaging target acquired by an OCT imaging system, to generate correction data for compensating for axial displacements between B-scans in the sequence caused by a relative motion of the OCT imaging system and the imaging target”

What changed
USPTO granted Patent US12599302B2 to OPTOS PLC for a method of processing C-scan data acquired by OCT imaging systems. The patent covers determining indicators of axial shift between adjacent B-scans and using frequency component analysis to compensate for relative motion between the imaging system and target during acquisition.
For companies developing OCT imaging systems or related ophthalmic diagnostic equipment, this patent establishes intellectual property constraints on motion-correction processing techniques. Competitors in the optical coherence tomography space should review the 24 claimed methods to assess potential licensing needs or design-around considerations.

Abstract
A method of processing C-scan data, which comprises a sequence of B-scans of an imaging target acquired by an OCT imaging system, to generate correction data for compensating for axial displacements between B-scans in the sequence caused by a relative motion of the OCT imaging system and the imaging target that varies a distance therebetween during acquisition of the B-scans, the correction data being generated by determining, for each pair of adjacent B-scans of a plurality of pairs of adjacent B-scans in the sequence, a respective indicator of an axial shift between respective representations of a common ocular feature in the adjacent B-scans; and determining, from a variation of the determined indicators with locations of the corresponding pairs of adjacent B-scans in the sequence, a first frequency component of the variation which is indicative of the relative motion during acquisition of the B-scans.
