Publication number: 20190180880Abstract: 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.Type: ApplicationFiled: February 18, 2019Publication date: June 13, 2019Inventors: Ifat Lavi, Ran Kornowski, Idit Avrahami, Nessi Benishti, Guy Lavi

Publication number: 20190164649Abstract: A vascular assessment apparatus is disclosed. The apparatus is configured to receive medical images of a coronary vessel tree of a subject from a medical imaging device and analyze the medical images to identify vessel segments within the coronary vessel tree. For each identified vessel segment, the apparatus is configured to analyze portions of the segment to determine at least one of a radius, diameter, or cross-sectional area of the vessel segment at the analyzed portions, determine resistances for the analyzed portions of the vessel segment based the radius, diameter, or the cross-sectional area at the analyzed portions, and combine the determined resistances for the analyzed portions of the vessel segment to determine a total resistance of the each identified vessel segment and calculate an index indicative of vascular function based on the determined flow rates.Type: ApplicationFiled: November 26, 2018Publication date: May 30, 2019Inventors: Ifat Lavi, Ran Kornowski, Idit Avrahami, Nessi Benishti, Guy Lavi

Patent number: 10141074Abstract: A vascular assessment apparatus is disclosed. The apparatus is configured to receive a stenotic model having measurements of a coronary vessel tree of a subject, the stenotic model created from a set of medical images recorded before the subject underwent a stent procedure. The apparatus is also configured to receive a post-medical image of the coronary vessel tree of the subject after the stent has been placed into the coronary vessel tree and identify vascular features within the post medical image that correspond to vascular features that are provided among the set of medical images. The apparatus is further configured to modify geometrical information for the corresponding vascular features in the stenotic model to create an updated stenotic model from the identified vascular features of the post medical image and calculate an index indicative of vascular function, based, at least in part, on the updated stenotic model.Type: GrantFiled: May 21, 2018Date of Patent: November 27, 2018Assignee: Cath Works Ltd.Inventors: Ifat Lavi, Ran Kornowski, Idit Avrahami, Nessi Benishti, Guy Lavi
