Blood vessels wall imaging catheter
First Claim
Patent Images
1. A method for imaging vulnerable plaque in coronary arteries, comprising:
- placing an optical fiber, formed of a scintillation detector within an artery;
obtaining a light signal at a proximal end, with respect to an operator, said light signal being an indicator of a scintillation event;
obtaining a reflected light signal, reflecting from a distal end; and
obtaining a time differentiation between said two signals, so as to obtain the distance from the operator to the point of the scintillation event.

Abstract
A system and method are provided for intravascular nuclear imaging, which is furthermore designed to locate the plaque along the artery and to estimate its thickness. Radiolabeled antibodies directed specific antigens in the atherosclerotic plaque or radiolabeled immunoscintigraphy pharmaceutical, which binds apoptotic cells, have been proposed for detection of vulnerable plaque. Other Radiopharmaceuticals such as Gallium Citrate, radio labeled white blood cells etc. call also be used to illuminate inflammatory processes.
