Latest Patents

One of Liu's latest patents is titled "Systems and methods for automated widefield optical coherence tomography angiography." This invention discloses systems and methods for generating wide-field optical coherence tomography angiography (OCTA) images. In this patent, multiple OCTA scans of a sample are automatically acquired at overlapping locations. The systems and methods include functionality to adaptively control the scanning procedure, allowing for real-time detection of eye blink and motion events during 3D scan acquisition. Additionally, methods for detecting and correcting motion-related artifacts in OCTA datasets are disclosed, enabling longer scan times over larger fields of view required for wide-field imaging. These methods may involve dividing en face angiogram images into motion-free parallel strips and applying registration methods to align overlapping strips into a motion-corrected composite image. A series of these images can be combined into a larger montage for wide-field OCTA imaging.

Another notable patent is for "Laser thermal conjunctivoplasty." This invention features a handheld laser probe designed for laser thermal conjunctivoplasty. The handheld laser comprises forceps and a line-focused laser light source coupled to the forceps. The forceps are configured to grasp a conjunctival fold and hold it in the light beam of the laser, which uniformly heats the conjunctival fold. The patent also discloses systems and methods for conjunctivoplasty using this handheld laser probe.
