Abstract
Systems, methods and apparatus are provided through which in some implementations changes in an aneurysm in a patient over time are identified by determining temporal differences between segmented aneurysms in a plurality of longitudinal exams and visually presenting the temporal differences.
Claims19
A method to image a patient, the method comprising:
- accessing four-dimensional image data that tracks a flow of a previously injected contrast agent through a vasculature;
- determining vessel flow information of the vasculature;
- determining mechanical force attributes on a wall of an aneurysm from the vessel flow information using a fluid dynamics model wherein the mechanical force attributes vary in proportion to velocity of fluid in the vasculature in a direction perpendicular to a plane of shear in the vasculature;
- generating a three-dimensional image of the vasculature using the four-dimensional image data;
- and
- visually presenting the determined mechanical force attributes in the three-dimensional image using visual cues to indicate degree of mechanical force attributes.
