   Optical coherence tomography (OCT) is an imaging modality based on fiberoptic technology. OCT imaging systems use optical imaging catheters that emit near-infrared light to produce high resolution, real-time images. The frequencies and bandwidths of infrared light are far higher than medical ultrasound signals, resulting in greatly increased image resolution, which is approximately ten-times higher than that of intravascular ultrasound. Compared with conventional imaging modalities, OCT is superior for the evaluation of vulnerable plaque features, which may be associated with a higher risk of peri-interventional myocardial infarction, such as plaque rupture, thrombus, thin-capped fibroatheroma and macrophages within the fibrous caps. OCT ... (Read Full Article)

2. Optic disc image in advanced age-related macular degeneration

   Evaluation of the optic disc and retinal nerve fiber layer is an essential part of the ophthalmic examination for diagnosis and for monitoring the progress of various types of optic neuropathy. Qualitative evaluation with stereoscopic optic disc photography is the traditional clinical method for the documentation of the optic disc appearance for serial comparisons. Recently, many imaging techniques have become available for optic disc and retinal nerve fiber layer evaluation. Confocal scanning laser ophthalmoscopy, scanning laser polarimetry and optical coherence tomography are currently the most widely used techniques by the ophthalmic community. These techniques have been reported to be reproducible ... (Read Full Article)

3. Use of optical coherence tomography in interventional cardiology

   Explore Article futuremedicine.com (Nov 7 2009) Cardiology

   Optical coherence tomography (OCT) has offered a greater understanding of coronary atherosclerosis with the ability to visualize plaque and quantify the thin, fibrous cap. Furthermore, OCT is able to traverse many of the limitations of angiography and intravascular ultrasound when imaging coronary stents in vivo. These applications are as a result of the use of near-infrared light, permitting an almost ‘histological’ resolution of the coronary artery. Novel developments with faster OCT pullback speeds (up to 20 mm/s with the next generation Fourier-domain systems) will further simplify the procedural requirements, meaning that the use of a proximal occlusion balloon is eliminated. ...
