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 2):
A vascular assessment apparatus comprising:\n a processor communicatively coupled to a medical imaging device; and a memory storing non-transitory computer-readable instructions, which when executed, cause the processor to:\n receive medical images of a coronary vessel tree of a subject from the medical imaging device; \n create a first model based on the medical images, the first model indicative of volumetric dimensions of the coronary vessel tree; \n create a second model based on the first model, the second model indicative of resistances to blood flow within the coronary vessel tree; \n at least one of (i) determine a location of a potential stenosis within the coronary vessel tree based on the resistances to blood flow of the second model, or (ii) receive an indication of the location of the potential stenosis; \n 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 store 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 \n process an adjustment to at least one of the first model, the second model, or the medical images based on the virtual revascularization at the location of the potential stenosis.
