Abstract
Systems and methods are described for the compositing together of model-linked vascular data from a plurality of sources, including at least one 2-D angiography image, for display in a frame of reference of the at least one angiography image. In some embodiments, a linking model comprises a data structure configured to link locations of angiographic images to corresponding elements of non-image vascular parameter data. The linking data structure is traversed to obtain a mapping to the frame of reference of one or more of the angiographic images.
Core Innovation
The disclosed invention relates to a system and method for preparing vascular parameter data for display using a linkage model that maps 2-D angiographic or medical images of a cardiac vasculature. The linkage model includes a plurality of 2-D angiographic images representing at least two separate viewing angles, and a data structure that links corresponding 2-D locations across the images, enabling cross-image correspondence of vascular locations.
The invention further provides a linkage model with a plurality of composite data sources that include different image or non-image information indexed to the 2-D locations. One or more composite data sources include information derived based on the angiographic images, and a processor determines vascular locations in a display image in a frame of reference of a particular 2-D angiographic or medical image and determines a correspondence between the vascular locations and the 2-D locations using the linkage data structure.
The processor causes presentation of a graphical user interface including the display image, where the graphical user interface responds to user input selecting one or more composite data sources. The user input triggers determination of the vascular parameter data based on the selected composite data sources, and the vascular parameter data is displayed in proximity to corresponding 2-D locations of the cardiac vasculature depicted in the particular 2-D angiographic or medical image.
Claims Coverage
The partial content identifies two independent claims: a system claim and a method claim. Across these independent claims, the inventive features center on a linkage model mapping 2-D locations across multiple 2-D angiographic or medical images and using user-selected composite data sources to update an overlay display of vascular parameter data in a common frame of reference.
Linkage model mapping 2-D image locations to common vascular region
A linkage model including a plurality of 2-D angiographic images representing respectively at least two separate viewing angles of a cardiac vasculature, and a data structure linking corresponding 2-D locations of at least a subset of the 2-D angiographic images, wherein the corresponding 2-D locations include representation in common of a region of the cardiac vasculature.
Composite data sources indexed to linked 2-D locations with image-derived information
A plurality of composite data sources, the composite data sources including different image or non-image information indexed to the 2-D locations, wherein one or more of the composite data sources include information derived based on the angiographic images or medical images.
Overlay display in a frame of reference based on determined correspondence
Determining vascular locations where vascular parameter data is to be displayed in a display image in a frame of reference of a particular 2-D angiographic or medical image of the at least a subset, and determining a correspondence between the vascular locations and the 2-D locations of the particular 2-D angiographic or medical image using the data structure.
User-driven selection of composite data sources to update proximal vascular parameter overlay
Causing presentation of a graphical user interface including the display image, wherein the graphical user interface responds to user input indicating selection of one or more of the composite data sources and updates to overlay the vascular parameter data on the display image, wherein the user input triggers determination of the vascular parameter data based on the selected composite data sources and the vascular parameter data is displayed in proximity to corresponding 2-D locations of the cardiac vasculature depicted in the particular 2-D angiographic or medical image.
The independent claims cover a linkage-model framework that maps linked 2-D locations across multiple 2-D angiographic or medical images into a common representation of a vascular region, indexes multiple composite data sources to those locations, and uses user input to select composite sources such that the system determines vascular locations in a frame of reference and overlays the resulting vascular parameter data in proximity to the corresponding 2-D vascular locations on the GUI display image.
