   An eye-tracked high resolution OCT device is presented for clinical multimodal imaging of the retina and the deep choroid, based on the platform of a commercial Heidelberg-Engineering SPECTRALIS® OCT device. The system is aimed to drive the development of novel therapeutic approaches for better eye care. The dual spectrometer based frequency domain OCT with built-in confocal scanning laser ophthalmoscope (SLO) operating at 735 nm, corrects for eye-motion in real time and enables arbitrary selection of the location of interest as well as automatic re-positioning of successive measurements or in follow up studies. Common clinical ophthalmic OCT devices perform raster scanning ...

   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. We upgraded our old designs in the following aspects. 1) This novel ...

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

   Explore Optical Coherence Tomography News Nov 17 2013 Dermatology

   

   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 ...

    To better understand pathophysiology during brain injuries such as stroke, we combined a number of OCT imaging techniques. Namely, we employed Doppler methods to map blood flow, angiography methods to measure capillary-level perfusion and vessel diameter, and scattering quantification methods to determine cell viability. 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 ...
