      Polymeric endovascular strut and lumen detection algorithm for intracoronary optical coherence tomography images
      Polymeric endovascular implants are the next step in minimally invasive vascular interventions. As an alternative to traditional metallic drug-eluting stents, these often-erodible scaffolds present opportunities and challenges for patients and clinicians. Theoretically, as they resorb and are absorbed over time, they obviate the long-term complications of permanent implants, but in the short-term visualization and therefore positioning is problematic. Polymeric scaffolds can only be fully imaged using optical coherence tomography (OCT ...

      Virtual phase conjugation based optical tomography for single-shot three-dimensional imaging
      We propose a virtual phase conjugation (VPC) based optical tomography (VPC-OT) for realizing single-shot optical tomographic imaging systems. Using a computer-based numerical beam propagation, the VPC combines pre-modulation and post-demodulation of the probe beams wavefront, which provides an optical sectioning capability for resolving the depth coordinates. In VPC-OT, the physical optical microscope system and VPC are coupled using digital holography. Therefore, in contrast to conventional optical tomographic imaging (OTI) systems ...

      Advanced Monte Carlo Simulation and Machine Learning for Frequency Domain Optical Coherence Tomography
      Optical Coherence Tomography(OCT) is a popular, rapidly growing imaging technique with an increasing number of bio-medical applications due to its noninvasive nature. However, there are three major challenges in understanding and improving an OCT system: (1) Obtaining an OCT image is not easy. It either takes a real medical experiment or requires days of computer simulation. Without much data, it is difficult to study the physical processes underlying OCT ...

      Optical Coherence Tomography (OCT) System With PHASE-SENSITIVE B-SCAN Registration
      This disclosure relates to the field of Optical Coherence Tomography (OCT). This disclosure particularly relates to an OCT system having a configuration that uses a phase sensitive B-scan registration method. In this disclosure, an OCT system may have a configuration that scans a physical object, acquires OCT signals to form B-scans, uses these B-scans to determine an optimal shift in an axial direction by using total phase error between B-scans ...

      Compressive sensing optical coherence tomography using randomly accessible lasers
      We propose and demonstrate a novel a compressive sensing swept source optical coherence tomography (SSOCT) system that enables high speed images to be taken while maintaining the high resolution offered from a large bandwidth sweep. Conventional SSOCT systems sweep the optical frequency of a laser (t) to determine the depth of the reflectors at a given lateral location. A scatterer located at delay appears as a sinusoid cos ((t) ) at ...

      Improved in vivo imaging of human blood circulation in the chorioretinal complex using phase variance method with new phase stabilized 1 μm swept-source optical coherence tomography (pv-SSOCT)
      We demonstrate the feasibility of our newly developed phase stabilized high-speed (100 kHz A-scans/s) 1 m sweptsource optical coherence tomography (SSOCT) system with the phase-variance based motion contrast method for visualization of human chorioretinal complex microcirculation. Compared to our previously reported spectral domain (spectrometer based) phase-variance (pv)-SDOCT system it has advantages of higher sensitivity, reduced fringe washout for high blood flow speeds and deeper penetration in choroid. High ...
