    2. Coagulation monitoring based on blood elastic measurement using optical coherence tomography

      Coagulation monitoring based on blood elastic measurement using optical coherence tomography
      Blood coagulation monitoring is important to diagnose hematological diseases and cardiovascular diseases and to predict the risk of bleeding and excessive clotting. In this study, we developed a system to dynamically monitor blood coagulation and quantitatively determine the coagulation function by blood elastic measurement. When blood forms a clot from a liquid, ultrasonic force induces a shear wave, which is detected by optical coherence tomography (OCT). The coagulation of porcine ...

    3. Volumetric vessel reconstruction method for absolute blood flow velocity measurement in Doppler OCT images

      Volumetric vessel reconstruction method for absolute blood flow velocity measurement in Doppler OCT images
      Doppler optical coherence tomography (DOCT) is considered one of the most promising functional imaging modalities for neuro biology research and has demonstrated the ability to quantify cerebral blood flow velocity at a high accuracy. However, the measurement of total absolute blood flow velocity (BFV) of major cerebral arteries is still a difficult problem since it not only relates to the properties of the laser and the scattering particles, but also ...

    5. Fully integrated optical coherence tomography, ultrasound, and indocyanine green-based fluorescence tri-modality system for intravascular imaging

      Fully integrated optical coherence tomography, ultrasound, and indocyanine green-based fluorescence tri-modality system for intravascular imaging
      We present a tri-modality imaging system and fully integrated tri-modality probe for intravascular imaging. The tri-modality imaging system is able to simultaneously acquire optical coherence tomography (OCT), ultrasound (US), and fluorescence imaging. Moreover, for fluorescence imaging, we used the FDA-approved indocyanine green (ICG) dye as the contrast agent to target lipid-loaded macrophages. We conducted imaging from a male New Zealand white rabbit to evaluate the performance of the tri-modality system ...

    6. Choroidal and Retinal Abnormalities by Optical Coherence Tomography in Endogenous Cushing’s Syndrome

      Choroidal and Retinal Abnormalities by Optical Coherence Tomography in Endogenous Cushing’s Syndrome
      Context: Cortisol has been suggested as a risk factor for choroidal thickening, which may lead to retinal changes. Objective: To compare choroidal thickness measurements using optical coherence tomography (OCT) in patients with endogenous active Cushings syndrome (CS) and to evaluate the occurrence of retinal abnormalities in the same group of patients. Design: Cross-sectional study. Setting: Outpatient clinic. Patients: Eleven female patients with CS in hypercortisolism state as determined by the ...

    7. Anatomically correct visualization of the human upper airway using a high-speed long range optical coherence tomography system with an integrated positioning sensor

      Anatomically correct visualization of the human upper airway using a high-speed long range optical coherence tomography system with an integrated positioning sensor
      The upper airway is a complex tissue structure that is prone to collapse. Current methods for studying airway obstruction are inadequate in safety, cost, or availability, such as CT or MRI, or only provide localized qualitative information such as flexible endoscopy. Long range optical coherence tomography (OCT) has been used to visualize the human airway in vivo , however the limited imaging range has prevented full delineation of the various shapes ...

    9. Diagnosis of subglottic stenosis in a rabbit model using long-range optical coherence tomography

      Diagnosis of subglottic stenosis in a rabbit model using long-range optical coherence tomography
      Objectives/Hypothesis Current imaging modalities lack the necessary resolution to diagnose subglottic stenosis. The aim of this study was to use optical coherence tomography (OCT) to evaluate nascent subglottic mucosal injury and characterize mucosal thickness and structural changes using texture analysis in a simulated intubation rabbit model. Study Design Prospective animal study in rabbits. Methods Three-centimeter-long sections of endotracheal tubes (ETT) were endoscopically placed in the subglottis and proximal trachea ...

      Apparatus and method for capturing a vital vascular fingerprint
      A method using optical coherence tomography to capture the microvascular network of the superficial layer of the finger skin for the purpose of fingerprint authentication and liveness detection. At the dermal papilla region, the vascular pattern follows the same pattern of the fingerprint and this vascular pattern forms a live vascular fingerprint. This live vascular fingerprint provides for ultrahigh security and a unique way for fingerprint-based personal verification. Because the ...

      Quantitative Evaluation of Adult Subglottic Stenosis Using Intraoperative Long-range Optical Coherence Tomography
      Objectives: To determine the feasibility of long-range optical coherence tomography (LR-OCT) as a tool to intraoperatively image and measure the subglottis and trachea during suspension microlaryngoscopy before and after endoscopic treatment of subglottic stenosis (SGS). Methods: Long-range optical coherence tomography of the adult subglottis and trachea was performed during suspension microlaryngoscopy before and after endoscopic treatment for SGS.

      Two Imaging Catheters Unite to Better Detect Dangerous Plaques in Arteries
      Collaboration between two National Institute of Biomedical Imaging and Bioengineering (NIBIB)-funded labs has revealed a promising new method for identifying atherosclerotic plaques, the encased deposits in arteries that restrict blood flow and can lead to heart attack or stroke. The technique combines two different types of imaging, allowing for an unprecedented combination of depth and detail. The hybrid technology will provide doctors with a better diagnostic tool for identifying ...

      Measurement of ciliary beat frequency using ultra-high resolution optical coherence tomography
      Ciliated epithelial cells populate up to 80% of the surface area of the human airway and are responsible for mucociliary transport, which is the key protective mechanism that provides the first line of defense in the respiratory tract. Cilia beat in a rhythmic pattern and may be easily affected by allergens, pollutants, and pathogens, altering ciliary beat frequency (CBF) subsequently. Diseases including cystic fibrosis, chronic obstructive pulmonary disease, and primary ...
