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.

Claims

1-20. -20. (canceled)

21. A system for displaying cardiovascular information of a patient, the system comprising:

at least one computer system configured to;

receive patient-specific data regarding a geometry of the patient'"'"'s heart;

create a model representing at least a portion of the patient'"'"'s heart based on the patient-specific data;

determine at least one value of a fractional flow reserve for at least the portion of the patient'"'"'s heart based on the model;

generate a report comprising a representation of at least the portion of the patient'"'"'s heart and one or more indicators of the value of the fractional flow reserve for at least the portion of the patient'"'"'s heart; and

display on the report an indicator of uncertainty associated with the value of the fractional flow reserve.

22. The system of claim 21, wherein the indicator of uncertainty is displayed overlapping the one or more indicators of the value of the fractional flow reserve on the report.

23. The system of claim 21, wherein the indicator of uncertainty is displayed when the value of the fractional flow reserve exceeds a predetermined threshold.

24. The system of claim 21, wherein the indicator of uncertainty is displayed when a predetermined threshold value of the fractional flow reserve falls within a range of the uncertainty.

25. The system of claim 21, wherein the computer system is further configured to:

display on the report a confidence that the value of the fractional flow reserve exceeds a predetermined threshold.

26. The system of claim 25, wherein the predetermined threshold is a threshold of functional significance of the fractional flow reserve.

27. The system of claim 21, wherein the computer system is further configured to:

analyze the patient-specific data to determine if a predetermined threshold of image quality is met; and

display an indicator of the image quality.

28. A computer-implemented method for displaying cardiovascular information of a patient, the system comprising:

receiving patient-specific data regarding a geometry of the patient'"'"'s heart;

creating a model representing at least a portion of the patient'"'"'s heart based on the patient-specific data;

determining at least one value of a fractional flow reserve for at least the portion of the patient'"'"'s heart based on the model;

generating a report comprising a representation of at least the portion of the patient'"'"'s heart and one or more indicators of the value of the fractional flow reserve for at least the portion of the patient'"'"'s heart; and

displaying on the report an indicator of uncertainty associated with the value of the fractional flow reserve.

29. The method of claim 28, wherein the indicator of uncertainty is displayed overlapping the one or more indicators of the value of the fractional flow reserve on the report.

30. The method of claim 28, wherein the indicator of uncertainty is displayed when the value of the fractional flow reserve exceeds a predetermined threshold.

31. The method of claim 28, wherein the indicator of uncertainty is displayed when a predetermined threshold value of the fractional flow reserve falls within a range of the uncertainty.

32. The method of claim 28, further comprising:

displaying on the report a confidence that the value of the fractional flow reserve exceeds a predetermined threshold.

33. The method of claim 32, wherein the predetermined threshold is a threshold of functional significance of the fractional flow reserve.

34. The method of claim 28, further comprising:

analyzing the patient-specific data to determine if a predetermined threshold of image quality is met; and

displaying an indicator of the image quality.

35. A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for displaying cardiovascular information of a patient, the method including:

receiving patient-specific data regarding a geometry of the patient'"'"'s heart;

creating a model representing at least a portion of the patient'"'"'s heart based on the patient-specific data;

determining at least one value of a fractional flow reserve for at least the portion of the patient'"'"'s heart based on the model;

generating a report comprising a representation of at least the portion of the patient'"'"'s heart and one or more indicators of the value of the fractional flow reserve for at least the portion of the patient'"'"'s heart; and

displaying on the report an indicator of uncertainty associated with the value of the fractional flow reserve.

36. The computer-readable medium of claim 35, wherein the indicator of uncertainty is displayed overlapping the one or more indicators of the value of the fractional flow reserve on the report.

37. The computer-readable medium of claim 35, wherein the indicator of uncertainty is displayed when the value of the fractional flow reserve exceeds a predetermined threshold.

38. The computer-readable medium of claim 35, wherein the indicator of uncertainty is displayed when a predetermined threshold value of the fractional flow reserve falls within a range of the uncertainty.

39. The computer-readable medium of claim 35, wherein the method further comprises:

displaying on the report a confidence that the value of the fractional flow reserve exceeds a predetermined threshold.

40. The computer-readable medium of claim 35, wherein the predetermined threshold is a threshold of functional significance of the fractional flow reserve.
