    2. High intensity focused ultrasound (HIFU) and phase-sensitive optical coherence tomography (PhS-OCT) for high resolution surface acoustic wave (SAW) elastography

      High intensity focused ultrasound (HIFU) and phase-sensitive optical coherence tomography (PhS-OCT) for high resolution surface acoustic wave (SAW) elastography
      Elastography has the ability of quantitatively evaluating the mechanical properties of soft tissue, thus is helpful for diagnosis and treatment monitoring for many diseases, e.g. skin diseases. Surface acoustic waves (SAWs) have been proven to be a non-invasive, non-destructive method for accurate characterization of tissue elastic properties.Current surface acoustic wave elastography using high energy laser pulse or mechanical shaker still have some problems. In order to improve SAW ...

    3. Quantitative measurement and real-time tracking of high intensity focused ultrasound using phase-sensitive optical coherence tomography: Feasibility study

      Quantitative measurement and real-time tracking of high intensity focused ultrasound using phase-sensitive optical coherence tomography: Feasibility study
      Purpose: Phase-sensitive optical coherence tomography (PhS-OCT) is proposed, as a new high intensity focused ultrasound (HIFU) imaging guidance to detect and track HIFU focus inside 1% agar samples in this work. The experiments studied the effect of varying HIFU power on the induction of shear wave, which can be implemented as a new technique to monitor focused ultrasound surgery (FUS). Method: A miniature HIFU transducer (1.02MHz, 20mm aperture diameter ...

    4. Effects of fixation and preservation on tissue elastic properties measured by quantitative optical coherence elastography (OCE)

      Effects of fixation and preservation on tissue elastic properties measured by quantitative optical coherence elastography (OCE)
      Fixed and preserved tissues have been massively used in the development of biomedical equipment and instrumentation. Not only the tissue morphology, but also its mechanical properties need to be considered in the fixation and preservation procedures since mechanical properties have significant influence on the design and performance of such instruments. Understanding the effects of storage and preservation conditions on the mechanical properties of soft tissue has both clinical and experimental ...

    5. Quantitative shear-wave optical coherence elastography with a programmable phased array ultrasound as the wave source

      Quantitative shear-wave optical coherence elastography with a programmable phased array ultrasound as the wave source
      The purpose of this study is to implement a beam-steering ultrasound as the wave source for shear-wave optical coherence elastography (SW-OCE) to achieve an extended range of elastic imaging of the tissue sample. We introduce a linear phased array ultrasound transducer (LPAUT) as the remote and programmable wave source and a phase-sensitive optical coherence tomography (OCT) as the sensitive shear-wave detector. The LPAUT is programmed to launch acoustic radiation force ...

    6. Micro-motion detection by optical coherence tomography (OCT) and its clinical applications (Thesis)

      Micro-motion detection by optical coherence tomography (OCT) and its clinical applications (Thesis)
      Detection of micro-motion on biological tissues has various applications such as ultrasound elastography and magnetic resonance elastography (MRE). Ultrasound transducers, the most commonly used tool to detect endogenous and exogenous micro-motions, have a number of drawbacks: including the requirements of the physical contact with the sample and limited spatial resolution (millimetre scale). The aim of this thesis is to develop a non-contact phase-sensitive imaging technique which is suitable for functional ...

    7. Quantitative shear wave optical coherence elastography (SW-OCE) with acoustic radiation force impulses (ARFI) induced by phase array transducer

      Quantitative shear wave optical coherence elastography (SW-OCE) with acoustic radiation force impulses (ARFI) induced by phase array transducer
      Shear Wave Optical Coherence Elastography (SW-OCE) uses the speed of propagating shear waves to provide a quantitative measurement of localized shear modulus, making it a valuable technique for the elasticity characterization of tissues such as skin and ocular tissue. One of the main challenges in shear wave elastography is to induce a reliable source of shear wave; most of nowadays techniques use external vibrators which have several drawbacks such as ...

    9. Detection and characterisation of biopsy tissue using quantitative optical coherence elastography (OCE) in men with suspected prostate cancer

      Detection and characterisation of biopsy tissue using quantitative optical coherence elastography (OCE) in men with suspected prostate cancer
      We present first quantitative three-dimensional (3D) data sets recorded using optical coherence elastography (OCE) for the diagnosis and detection of prostate cancer (PCa). 120 transrectal ultrasound guided prostate biopsy specimens from 10 men suspected with prostate cancer were imaged using OCE. 3D quantitative mechanical assessment of biopsy specimens obtained in kilopascals (kPa) at an interval of 40m was compared with histopathology. Sensitivity, specificity, and positive and negative predictive values were ...
