Index matching to improve optical coherence tomography imaging through blood.
BACKGROUND Most myocardial infarctions are caused by the rupture of small rather than large plaques in the arteries of the heart that are beyond the detection limit of current technologies. METHODS AND RESULTS Recently, optical coherence tomography (OCT) has demonstrated considerable potential as a method for high-resolution assessment of vulnerable plaque. However, intravascular OCT imaging ...
متن کاملUse of a blood substitute to determine instantaneous murine right ventricular thickening with optical coherence tomography.
BACKGROUND A satisfactory imaging technique to determine regional wall thickening of the murine myocardium is not available. Although cardiovascular imaging with light offers a novel solution, application is problematic because scattering by erythrocytes causes significant optical attenuation. METHODS AND RESULTS Optical coherence tomography (OCT) is a technique for detailed resolution imagin...
متن کاملChoice of Intracoronary Imaging: When to use Intravascular Ultrasound or Optical Coherence Tomography.
Intracoronary imaging has the capability of accurately measuring vessel and stenosis dimensions, assessing vessel integrity, characterising lesion morphology and guiding optimal percutaneous coronary intervention (PCI). Coronary angiography used to detect and assess coronary stenosis severity has limitations. The 2D nature of fluoroscopic imaging provides lumen profile only and the assessment o...
متن کاملIntegrated intravascular optical coherence tomography ultrasound imaging system.
We report on a dual-modality optical coherence tomography (OCT) ultrasound (US) system for intravascular imaging. To the best of our knowledge, we have developed the first integrated OCT-US probe that combines OCT optical components with an US transducer. The OCT optical components mainly consist of a single-mode fiber, a gradient index lens for light-beam focusing, and a right-angled prism for...
متن کاملComposition Imaging System for Intravascular Optical Coherence Tomography “Compovision-OCT”
Now that we are facing the advent of the super-aging society where people over 65 years old account for greater than a quarter of the nation’s population, the growth of medical spending is becoming a serious social problem. Under these circumstances, efficient treatment that accords with the seriousness of the disease is required to reduce medical spending, and diagnostic methods to obtain more...
