    3. Robust phase unwrapping for phase images in Fourier domain Doppler optical coherence tomography

      Robust phase unwrapping for phase images in Fourier domain Doppler optical coherence tomography
      To solve the 2 2 phase ambiguity for phase-resolved Doppler images in Doppler optical coherence tomography, we present a modified network programming technique for the first time to the best of our knowledge. The proposed method assumes that error of the discrete derivatives between unwrapped phase image and wrapped phase image can be arbitrary values instead of integer-multiple of 2 2 , which makes the real-phase restoration accurate and robust against ...

    4. Adaptive anisotropic diffusion for noise reduction of phase images in Fourier domain Doppler optical coherence tomography

      Adaptive anisotropic diffusion for noise reduction of phase images in Fourier domain Doppler optical coherence tomography
      Phase image in Fourier domain Doppler optical coherence tomography offers additional flow information of investigated samples, which provides valuable evidence towards accurate medical diagnosis. High quality phase images are thus desirable. We propose a noise reduction method for phase images by combining a synthetic noise estimation criteria based on local noise estimator (LNE) and distance median value (DMV) with anisotropic diffusion model. By identifying noise and signal pixels accurately and ...

    7. Accurate real-time depth control for CP-SSOCT distal sensor based handheld microsurgery tools

      Accurate real-time depth control for CP-SSOCT distal sensor based handheld microsurgery tools
      This paper presents a novel intuitive targeting and tracking scheme that utilizes a common-path swept source optical coherence tomography (CP-SSOCT) distal sensor integrated handheld microsurgical tool. To achieve micron-order precision control, a reliable and accurate OCT distal sensing method is required; simultaneously, a prediction algorithm is necessary to compensate for the system delay associated with the computational, mechanical and electronic latencies. Due to the multi-layered structure of retina, it is ...

    9. Evaluation of Microvascular Anastomosis Using Real-Time, Ultra-High-Resolution, Fourier Domain Doppler Optical Coherence Tomography

      Evaluation of Microvascular Anastomosis Using Real-Time, Ultra-High-Resolution, Fourier Domain Doppler Optical Coherence Tomography
      Background: Evolution in microsurgical techniques and tools has paved the way for supermicrosurgical anastomoses, with vessel diameters often approaching below 0.8 mm in the clinical realm and even smaller (0.2 to 0.3 mm) in murine models. Several imaging and monitoring devices have been introduced for postoperative monitoring, but intraoperative guidance, assessment, and predictability have remained limited to binocular optical microscopy and the surgeons experience. The authors present ...
