    2. Feature Of The Week 2/3/13: Automated Segmentation Algorithm for Medical Image Processing using Optical Coherence Tomography

      Feature Of The Week 2/3/13: Automated Segmentation Algorithm for Medical Image Processing using Optical Coherence Tomography
      Optical coherence tomography (OCT) is a noninvasive optical imaging technique for in vivo and in situ imaging of microstructure in biological tissues. Improvements in identification, imaging, and visualization of biological microstructures are necessary before OCT clinical use. Using the proposed algorithm, OCT images of the prostate and cervicovaginal epithelium were segmented to differentiate the cavernous nerves from the prostate gland and to detect minute changes in the epithelial layer, respectively ...

    3. Application of optical coherence tomography and high-frequency ultrasound imaging during noninvasive laser vasectomy

      Application of optical coherence tomography and high-frequency ultrasound imaging during noninvasive laser vasectomy
      A noninvasive approach to vasectomy may eliminate male fear of complications related to surgery and increase its acceptance. Noninvasive laser thermal occlusion of the canine vas deferens has recently been reported. Optical coherence tomography (OCT) and high-frequency ultrasound (HFUS) are compared for monitoring laser thermal coagulation of the vas in an acute canine model. Bilateral noninvasive laser coagulation of the vas was performed in six dogs (n = 12 vasa) using ...

    4. Enhanced thulium fiber laser lithotripsy using micro-pulse train modulation

      Enhanced thulium fiber laser lithotripsy using micro-pulse train modulation
      The thulium fiber laser (TFL) is currently being studied as an alternative to the conventional holmium:YAG (Ho:YAG) laser for lithotripsy. The diode-pumped TFL may be electronically modulated to operate with variable parameters (e.g., pulse rate, pulse duration, and duty cycle) for studying the influence of pulse train mode on stone ablation rates. The TFL under study was operated at 1908 nm, 35-mJ pulse energy, and 500-μs pulse ...

    6. Feature Of The Week 10/3/10: Combined Image-Processing Algorithms for Improved OCT Imaging of Prostate Nerves

      Feature Of The Week 10/3/10: Combined Image-Processing Algorithms for Improved OCT Imaging of Prostate Nerves
      Feature Of The Week 10/3/10: The cavernous nerves are responsible for sexual function. These nerves are at risk of injury during surgical dissection and removal of a cancerous prostate gland because of the close proximity of the nerves to the prostate surface. Their microscopic nature also makes it difficult to predict the true course and location of these nerves from one patient to another. These observations may explain ...

    10. Wavelet denoising during optical coherence tomography of the prostate nerves using the complex wavelet transform

      Wavelet denoising during optical coherence tomography of the prostate nerves using the complex wavelet transform
      Preservation of the cavernous nerves during prostate cancer surgery is critical in preserving sexual function after surgery. Optical coherence tomography (OCT) of the prostate nerves has recently been studied for potential use in nerve-sparing prostate surgery. In this study, the discrete wavelet transform and complex dual-tree wavelet transform are implemented for wavelet shrinkage denoising in OCT images of the rat prostate. Applying the complex dual-tree wavelet transform provides improved results ...

    11. All-fiber common-path optical coherence tomography: sensitivity optimization and system analysis

      All-fiber common-path optical coherence tomography: sensitivity optimization and system analysis
      A fully integrated all-fiber implementation of common-path interferometer-based optical coherence tomography (OCT) has been successfully demonstrated. Unlike conventional Michelson-based OCT systems, there is no separate reference arm as the reference signal is derived from the probe-end back reflection. This leads to "downlead insensitivity", which makes the device more compatible with existing endoscopic medical instruments. We also theoretically analyze the optimization of system sensitivity in balanced and unbalanced detection. We have ...
