a second representation of the at least three representations comprises an anatomy image of the portion of the artery oriented parallel to the first axis, wherein a first end of the anatomy image corresponds to a proximal end of the portion of the artery and is aligned with the first end of the first axis, and a second end of the anatomy image corresponds to a distal end of the portion of the artery and is aligned with the second end of the first axis; and
a third representation of the at least three representations comprises a model of the portion of the artery oriented parallel to the first axis and an indicator, on the model, of the at least one value of the blood flow characteristic at a corresponding location in the portion of the artery, wherein a first end of the model corresponds to a proximal end of the portion of the artery and is aligned with the first end of the first axis and the first end of the anatomy image, and a second end of the model corresponds to a distal end of the portion of the artery and is aligned with the second end of the first axis and the second end of the anatomy image.

Abstract
Embodiments include a system for displays cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient'"'"'s heart and create a model representing at least a portion of the patient'"'"'s heart based on the patient-specific data. The computer system may determine at least one value of the blood flow characteristic within the patient'"'"'s heart based on the model. The computer system may also display a report comprising a representation of at least one artery corresponding to at least a portion the model, and display one or more indicators of the value of the blood flow characteristic on a corresponding portion of the at least one artery.
