What changed

USPTO granted patent US12588808B2 to Aliph Medical Inc. on March 31, 2026. The patent covers a system and method for providing accurate lateral mapping of images using a modulator synced to the imaging engine clock to generate markers that remove distortions and create spatially-accurate mapping. The technology applies to ocular biometry and topography, including OCT arrangements for simultaneous cornea and retina imaging, and on-axis imaging systems for ocular surface quality evaluation. Muhammad Al-Qaisi is the inventor.

This is a routine patent grant notification with no compliance deadlines or required actions for third parties. Medical device manufacturers developing ocular imaging or OCT technologies should review the patent claims to assess potential licensing needs orFreedom-to-operate concerns for their existing or planned products in this space.

Abstract

A system for providing accurate lateral mapping of images acquired via a scanning mechanism has a modulator synced to the imaging engine clock to generate image markers. The markers are then used to remove distortions and generate spatially-accurate mapping. A method of correcting image distortions by identifying the modulations and removing the distortions according to the spacing of the modulations. The system and the method applicable to ocular biometry and topography with the inclusion of an OCT arrangement to image the whole eye while the traversing the cornea and retina simultaneously, and with the inclusion of an on-axis imaging system to evaluate the quality of the ocular surface.
