    2. Feasibility study of using the dispersion of surface acoustic wave (SAW) impulse for viscoelasticity characterization in tissue mimicking phantoms

      Feasibility study of using the dispersion of surface acoustic wave (SAW) impulse for viscoelasticity characterization in tissue mimicking phantoms
      The aim of this study was to investigate the feasibility of utilizing the phase velocity dispersion of impulse surface acoustic wave (SAW) for viscoelasticity characterization of soft materials. The focused ultrasound transducer and the phase sensitive optical coherence tomography (PhS‐OCT) were applied as the impulse SAW inducer and tracker respectively. Three types of liquid‐paraffin‐based cream‐in‐agar phantoms were tested. Phase velocity dispersion curve was extracted using ...

    3. Quantitative assessment of the mechanical properties of prostate tissue with optical coherence elastography

      Quantitative assessment of the mechanical properties of prostate tissue with optical coherence elastography
      Prostate cancer (PCa) is a heterogeneous disease with multifocal origin. In current clinical care, the Gleason scoring system is the well-established diagnosis by microscopic evaluation of the tissue from trans-rectal ultrasound (TRUS) guided biopsies. Nevertheless, the sensitivity and specificity in detecting PCa can range from 40 to 50% for conventional TRUS B-mode imaging. Tissue elasticity is associated with the disease progression and elastography technique has recently shown promise in aiding ...

    4. 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 ...

    5. 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 ...

    7. 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 ...

  2. About Ghulam Nabi

    Ghulam Nabi

    Ghulam Nabi is clinical reader in surgical uro-oncology and Clinical Head of Division of Imaging and Technology at Ninewells Hospital, University of Dundee. Besides heading the academic section of Urology at the University of Dundee, Mr Nabi is lead for prostate cancer Surgery in Tayside and chair of Tayside Urological Cancers Network. He introduced a number of minimally invasive surgical techniques for Tayside including laparoscopic surgery in prostate cancer, single port surgery and cryoablation for renal cancers. Mr Nabi’s research programme of “early detection and minimally invasive treatment” for urological cancers focuses on: 1. Biomarkers for urological cancers (Genetic and Proteomics) 2. Technology appraisal (evidence synthesis) and basic research in surgical technology in the area of unmet needs. 3. Surgical technology, lasers, Raman spectroscopy, Biophotonics, Elastography and Focused Ultrasound Surgery (FUS) 4. Long-term cohort studies including use of secondary datasets.
