    1. Assessing the Effect of Middle Ear Effusions on Wideband Acoustic Immittance Using Optical Coherence Tomography

      Assessing the Effect of Middle Ear Effusions on Wideband Acoustic Immittance Using Optical Coherence Tomography
      Objectives: Wideband acoustic immittance (WAI) noninvasively assesses middle ear function by measuring the sound conduction over a range of audible frequencies. Although several studies have shown the potential of WAI for detecting the presence of middle ear effusions (MEEs), determining the effects of MEE type and amount on WAI in vivo has been challenging due to the anatomical location of middle ear cavity. The purpose of this study is to ...

    2. Method and apparatus for obtaining a three-dimensional map of tympanic membrane thickness

      Method and apparatus for obtaining a three-dimensional map of tympanic membrane thickness
      Methods and apparatus for combining a low coherence interferometry (LCI) technique for single-point thickness measurement with videootoscopy for recording the image of a tissue such as the tympanic membrane (TM). TM thickness distribution maps are obtained by mapping the LCI imaging sites onto an anatomically accurate wide-field image of the TM, generated by mosaicking a sequence of multiple small field-of-view video-otoscopy images.

    7. Local wavefront mapping in tissue using computational adaptive optics OCT

      Local wavefront mapping in tissue using computational adaptive optics OCT
      The identification and correction of wavefront aberrations is often necessary to achieve high-resolution optical images of biological tissues, as imperfections in the optical system and the tissue itself distort the imaging beam. Measuring the localized wavefront aberration provides information on where the beam is distorted and how severely. We have recently developed a method to estimate the single-pass wavefront aberrations from complex optical coherence tomography (OCT) data. Using this method ...

    8. Interstitial magnetic thermotherapy dosimetry based on shear wave magnetomotive optical coherence elastography

      Interstitial magnetic thermotherapy dosimetry based on shear wave magnetomotive optical coherence elastography
      While magnetic thermoseeds are often utilized in interstitial magnetic thermotherapy (iMT) to enable localized tumor ablation, we propose to extend their use as the perturbative source in magnetomotive optical coherence elastography (MM-OCE) so that the heat-induced elasticity alterations can be theranostically probed. MM-OCE measurements were found to agree with indentation results. Tissue stiffening was visualized on iMT-treated porcine liver and canine soft tissue sarcoma specimens, where histology confirmed thermal damages ...

      Economical and compact briefcase spectral-domain optical coherence tomography system for primary care and point-of-care applications
      Development of low-cost and portable optical coherence tomography (OCT) systems is of global interest in the OCT research community. Such systems enable utility broadly throughout a clinical facility, or in remote areas that often lack clinical infrastructure. We report the development and validation of a low-cost, portable briefcase spectral-domain optical coherence tomography (SD-OCT) system for point-of-care diagnostics in primary care centers and/or in remote settings. The self-contained briefcase OCT ...

      Intraoperative imaging of surgical margins of canine soft tissue sarcoma using optical coherence tomography
      Optical coherence tomography (OCT) is a rapid non‐invasive imaging technique that has shown high sensitivity for intraoperative surgical margin assessment in human breast cancer clinical trials. This promising technology has not been evaluated in veterinary medicine. The objective of this study was to correlate normal and abnormal histological features with OCT images for surgical margins from excised canine soft tissue sarcoma (STS) and to establish image evaluation criteria for ...

      Magnetomotive Displacement of the Tympanic Membrane using Magnetic Nanoparticles: Toward Enhancement of Sound Perception
      Objective: A novel hearing-aid scheme using magnetomotive nanoparticles (MNPs) as transducers in the tympanic membrane (TM) is proposed, aiming to noninvasively and directly induce a modulated vibration on the TM. Methods: In this feasibility study, iron-oxide (Fesub3/subOsub4/sub) nanoparticles were applied on ex vivo rat TM tissues and allowed to diffuse over ~2 hr.

    15. Wavefront measurement using computational adaptive optics

      Wavefront measurement using computational adaptive optics
      In many optical imaging applications, it is necessary to correct for aberrations to obtain high quality images. Optical coherence tomography (OCT) provides access to the amplitude and phase of the backscattered optical field for three-dimensional (3D) imaging samples. Computational adaptive optics (CAO) modifies the phase of the OCT data in the spatial frequency domain to correct optical aberrations without using a deformable mirror, as is commonly done in hardware-based adaptive ...

    20. Investigating the healing mechanisms of an angiogenesis-promoting topical treatment for diabetic wounds using multimodal microscopy

      Investigating the healing mechanisms of an angiogenesis-promoting topical treatment for diabetic wounds using multimodal microscopy
      Impaired skin wound healing is a significant co-morbid condition of diabetes that is caused by poor microcirculation, among other factors. Studies have shown that angiogenesis, a critical step in the wound healing process in diabetic wounds, can be promoted under hypoxia. In this study, an angiogenesis-promoting topical treatment for diabetic wounds, which promotes angiogenesis by mimicking a hypoxic environment via inhibition of prolyl hydroxylase resulting in elevation or maintenance of ...
