Optical Coherence Tomography Guided Robotic Needle Insertion for Deep Anterior Lamellar Keratoplasty
Deep anterior lamellar keratoplasty (DALK) is a promising form of partial-thickness cornea transplantation, but its popular “big bubble” technique frequently fails due to difficulty controlling a needle insertion into the cornea. We addressed the surgeon challenges that reduce success rates by demonstrating an optical coherence tomography (OCT)-guided, robotically stabilized workstation for manually or automatically performing DALK needle insertions. In a study with cornea fellows, we found that OCT visualization versus the standard stereo microscope was a key enabler in manual attempts and that our automatic robotic method met or exceeded the performance of cornea fellows...

Optimized Automated Segmentation and 3D Reconstruction Using Intracoronary Optical Coherence Tomography
Real time segmentation and three-dimensional (3D) reconstruction of the coronary arteries is challenging and limited by the increased computational time of the developed computer-aided methods. We present a novel and time-efficient method for intracoronary lumen detection which produces 3D coronary... Read more

Lumen Segmentation in Intravascular Optical Coherence Tomography Using Backscattering Tracked and Initialized Random Walks
Intravascular imaging using optical coherence tomography (OCT) is commonly used in interventional cardiology for proper diagnosis and surgical planning. OCT provides high-­‐resolution images for detailed investigation of atherosclerosis induced thickening of the lumen wall resulting in arterial blockage and triggering... Read more
