5. Optics may speed breast cancer diagnosis

   Explore Article Futurity.org (Dec 10 2009) Oncology

   U. ILLINOIS—Waiting for laboratory results is often one of the most stressful aspects of a breast cancer diagnosis. A new optical imaging system aims to ease that stress by giving doctors performing lumpectomies real-time information on breast cancer tissue margins while still in the operating room. Developed by Stephen Boppart, professor of electrical and computer engineering, bioengineering, and medicine, at the University of Illinois, the imaging system uses optical coherence ...

   Explore Article opticsinfobase.org (Dec 2 2009)

   The availability of a real-time non-destructive modality to interrogate the mechanical properties of viscoelastic materials would facilitate many new investigations. We introduce a new optical method for measuring elastic properties of samples which employs magnetite nanoparticles as perturbative agents. Magnetic nanoparticles distributed in silicone-based samples are displaced upon probing with a small external magnetic field gradient and depth-resolved optical coherence phase shifts allow for the tracking of scatterers in the ...

   Explore Article SPIE Digital Library (Nov 25 2009)

   Dynamic optical coherence elastography, an emerging optical technique to measure material mechanical properties using the non-invasive imaging modality of optical coherence tomography is introduced. Dynamic mechanical excitations were applied to the samples while a spectral domain optical coherence tomography system was used for detection. Based on a simple mechanical model, material mechanical properties such as Young's moduli can be extracted from detected phaseresolved signals. Biological tissues and their biomechanical properties ... (Read Full Article)

    PHILADELPHIA -- November 18, 2009 -- Intraoperative optical coherence tomography (OCT) rapidly images larger breast tumour margin areas, dramatically improving the microscopic sampling rate or analysis of the margin, according to research published in the November 15 issue of Cancer Research. "Intraoperative OCT has the potential to provide diagnostically useful information about margin status in real time, at the point of care, rather than relying on postoperative histopathology," said Stephen ...

    Dynamic optical coherence elastography is used to determine in vivoskin biomechanical properties based on mechanical surface wave propagation. Quantitative Youngs moduli are measured on human skin from different sites, orientations, and frequencies. Skin thickness, including measurements from different layers, are also measured simultaneously. Experimental results show significant differences among measurements from different skin sites, between directions parallel and orthogonal to Langers lines, and under different skin hydration states. Results also ... (Read Full Article)

    Acoustomotive optical coherence elastography (AM-OCE), a dynamic and internal excitation optical coherence elastography technique, is reported. Acoustic radiation force was used for internal mechanical excitation, and spectral-domain optical coherence tomography was used for detection. Mechanical properties of gelatin tissue phantoms were measured by AM-OCE and verified using rheometry results. Measured mechanical properties including shear moduli and shear damping parameters of the gelatin samples double when their polymer concentration increases from ... (Read Full Article)
