Fluid injector for simultaneous anatomic and hydrodynamic analysis in coronary angiography

摘要

A method for imaging individual coronary arteries comprises using an actuator to emit pulses of radiation impervious pigments in individual coronary arteries.The method further includes acquiring a series of invasive coronary X-ray angiograms of pulses of a radiopaque dye using an image capture device.The method further uses a processor to track the pulse through a series of invasive coronary X-ray angiographic images to identify the location of the pulse on a three-dimensional (3D) structural model of the coronary artery system and to indicate the locus of the pigment when the dye is flowing through the various arterial branches It includes generating a three-dimensional (3D) functional model of coronary arteries.
