      Feature Of The Week 12/8/2013: Tuning of Vernier Tuned DBR Lasers for Optical Comb Swept Source OCT

      Monolithic Vernier tuned distributed Bragg reflector (VT-DBR) lasers are expected to become one of the most promising sources for optical comb swept source optical coherence tomography (SS-OCT) with reduced sensitivity roll-off due to a long coherence length, potential capability for a very fast A-scan rate, and low cost with monolithic structure. However, mainly four problems inhibited an ideal implementations: 1) frequencies deviate from the targeted values when scanned, 2) large amounts of noise appear associated with abrupt changes in injection currents, 3) optically aliased noise appears due to a long coherence length, and 4) the narrow wavelength coverage of a ...

      Combined use of intravascular ultrasound (IVUS) and optical coherence tomography (OCT) holds the potential of combining the strengths of both imaging modalities and improving the diagnostic accuracy of atherosclerotic plaque vulnerability. In this manuscript, we reported a co-registered intracoronary OCT-IVUS system and catheter with real-time imaging and polar-coordinate displaying capability, well-suited for clinical utilization in guiding interventional cardiologists. With an eventual goal of clinical use in humans, this novel catheter design and modified software are poised to strengthen the ability to diagnose vulnerable plaques in patients in real-time.

      Feature Of The Week 11/17/13: Monitoring of wound healing process of human skin after fractional laser treatments with optical coherence tomography

      Fractional photothermolysis induced by non-ablative fractional lasers (NAFLs) or ablative fractional lasers (AFLs) can remodel the skin, regenerate collagen, and remove tumor tissue. However, fractional laser treatments may result in severe side effects, and multiple treatments are required to achieve the expected outcome. Thus, the treatment outcome and downtime after fractional laser treatments are key issues to determine the following treatment strategy. In this study, an optical coherence tomography (OCT) system was implemented for in vivo studies of wound healing after NAFL and AFL treatments. According to the OCT scanning results, the laser-induced photothermolysis including volatilization and coagulation could be ...

      Raman spectroscopy and Optical Coherence Tomography (OCT) are two optical tools that have shown potential to be used for discriminating between normal and abnormal tissue types. Although both of these non-invasive techniques are capable of discriminating between normal and tumour tissues, in many cases, they are unable individually to provide both the high specificity and high sensitivity required for disease diagnosis. Raman spectroscopy and OCT provides complementary information. While Raman spectroscopy provides information about chemical composition of tissues, OCT provides morphological information of tissues. So combining this complementary information might be able to provide higher diagnostic accuracy that is clinically ...

This multi-parametric approach was used to perform imaging in the acute and recovery stages in experimental ischemic stroke, with the goal of determining the fate of the penumbra using imaging biomarkers. The penumbra is an area of brain tissue which is compromised during stroke but could be salvaged through thrombolysis or other treatment methods. Multi-parametric imaging ...
