Abstract:
A method for real-time vascular modeling and assessment is disclosed. Modeling, in some embodiments, comprises receiving a plurality of 2-D angiographic images of a portion of a vasculature of a subject, and processing the images to automatically detect 2-D features, for example, paths along vascular extents, which are projected into 3-D to determine homologous features among blood vessels and construct 3-D vascular extents and determine other vascular characteristics. Assessment, in some embodiments, comprises processing models selectively different from one another to produce one or more vascular indexes which indicate a diagnostic preference, for example, to perform a medical intervention such as a stent implantation. Speed is achieved, for example, by the method being optimized for determining the effects of a medical intervention. In some embodiments, results are produced quickly enough to allow use of the method to perform PCI within the same catheterization used to perform diagnostic imaging.

Claim (Index 16):
A vascular assessment apparatus storing non-transitory computer-readable instructions, which when executed, cause the apparatus to:\n receive a model of a coronary vessel tree of a subject; at least one of (i) determine a location of a potential stenosis within the coronary vessel tree, or (ii) receive an indication of the location of the potential stenosis; perform a virtual revascularization at the location of the potential stenosis by at least one of\n (a) determine coronary vessel segments that are proximal and distal to the location of the potential stenosis, calculate a coronary edge by interpolating dimensions of the determined proximal and distal coronary vessel segments through the location of the potential stenosis, and storing the interpolating dimensions as inflated dimensions of the location of the potential stenosis, or \n (b) determine coronary vessel segments that are proximal and distal to the location of the potential stenosis, determine mean values of diameters of the determined proximal and distal coronary vessel segments, determine an average of the determined values, and store the determined average as an inflated diameter of the location of the potential stenosis; and \n process an adjustment to the model based on the virtual revascularization at the location of the potential stenosis.
