Abstract
Systems and methods are provided herein for determining areas of low blood flow, low blood perfusion, suboptimal treatment perfusion, and/or likelihood of tumor recurrence. For example patient-specific methods are provided for identifying areas of low perfusion in an anatomy of interest (such as a vascular region). Angiography data corresponding to the anatomy of interest can be used to generate a modified three-dimensional (3D) model of the anatomy of interest, which represents a fluid flow system exhibiting variant flow patterns. The model can take into account patient-specific data to simulate physical characteristics of the fluid flow system. This provides for accurate determination of localized areas of low perfusion, which can be indicative of potential tumor recurrence.
