Systems and methods for enhanced user interface and crosstalk analysis for cardiac index determination. An example method includes accessing a cardiac model of a portion of a patient's heart, the portion including one or more vessels of the patient's heart, and the cardiac model indicating a plurality of lesions along a length of at least one of the vessels; obtaining, based on the cardiac model for the lesions, respective positions along the length for which the lesions are associated with index drops, wherein the index drops are with respect to an index indicative of vascular function; and causing presentation of a user interface, wherein the user interface: presents a graph mapping the length to the index indicative of vascular function, presents individual toggles enabling nulling of individual lesions, and updates the graph in response to received user input to one or more of the toggles, wherein the user input nulls effects of one or more lesions.

Systems and methods for secure sharing of cardiac assessments using QR codes. An example method may include presenting a cardiac analysis on a user interface; receiving, on the user interface, user input to display at least one QR code configured to share the cardiac analysis; in response to the input, generating the at least one QR code which encodes at least a portion of the cardiac analysis and removes protected health information (PHI), wherein the portion includes one or more of a screenshot or a report associated with the cardiac analysis; and displaying the at least one QR code on the user interface.

Systems and methods for displaying flow index values on a user interface. An example method may include receiving medical images imaging a portion of a vasculature of a subject, with the portion of the vasculature including vessels; producing, by automatic processing of the medical images, a three-dimensional vascular model of the portion of the vasculature comprising the one or more vessels based on the medical images; calculating flow index values quantifying vascular function along each of the one or more vessels based on the three-dimensional vascular model; displaying a representation of the three-dimensional vascular model comprising the one or more vessels; and for a designated vessel of the one or more vessels, simultaneously displaying the flow value index for a designated location of the designated vessel along with the flow value index for a predetermined distal location along a length of the designated vessel.

An automated measurement device and method for coronary artery disease scoring is disclosed. An example device includes a processor configured to obtain a computerized model of a plurality of vascular segments of a patient and create an unstenosed computerized model from the computerized model by virtually enlarging at least some locations of the vascular segments of the computerized model. The processor also determines vascular state scoring tool (“VSST”) scores based on characteristics of vascular locations along the vascular segments. The processor further determines a severity of stenosis for the vascular locations based on comparisons of first blood flow parameter values at the vascular locations in the computerized model to corresponding second blood flow parameter values at the same vascular locations in the unstenosed computerized model. A user interface of the device displays the severity of stenosis in conjunction with the VSST scores for the vascular locations.

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.

Systems and methods for enhanced parallel operation of user interface for cardiac index determination. An example method includes accessing medical images depicting a portion of a patient's heart. A unified user interface is presented which allows for a user to select medical images for analysis, with the unified user interface allowing a user to select a lesion and adjust detected vessels on a first medical image while the system is detecting vessels on a different medical image displayed on the unified user interface without navigating to a later user interface.
