Claim of US Patent No. 10,169,543

1. A system for displaying cardiovascular information of a patient, the system comprising:at least one computer system configured to:
receive patient-specific image data regarding a geometry of one or more of the patient's arteries;
create a model representing at least a portion of the patient's arteries based on the patient-specific image data;
determine at least one value of a fractional flow reserve for at least the portion of the patient's arteries based on the model;
generate a report for visual display comprising a representation of at least the portion of the patient's arteries and a summary portion including a listing of the represented portion of the patient's arteries adjacent to a graph of one or more markers of the value of the fractional flow reserve for each respective portion of the patient's arteries;
display, on the graph of the summary portion of the report, an indicator of uncertainty for each determined value of the fractional flow reserve, wherein each indicator of uncertainty is displayed as a bar overlapping a respective marker of fractional flow reserve on the graph of the summary portion of the report, and wherein each indicator of uncertainty is displayed when it cannot be determined whether the respective value of the fractional flow reserve exceeds the predetermined threshold value.
