Abstract:
1. A method for producing a simulation of subject-specific blood flow of a heart in a subject, the method comprising: (a) scanning an endocardial surface of the heart in the subject, utilizing a diagnostic imaging system, to obtain a computed tomography (CT) image of the endocardial surface of the heart, wherein the scanning captures a complex and detailed structure of heart walls and trabeculae; (b) decimating a mesh of the computed tomography image obtained from step (a) utilizing a computing device to a size sufficient to capture fine details of the heart, wherein the decimation allows collapse of one vertex into one of its neighbors; (c) performing detail-preserving smoothing of the mesh from step (b), utilizing a computing device, wherein the smoothing is restricted to a tangential direction; and (d) remeshing a triangular mesh from step (c) with an incremental isotropic remeshing technique, utilizing a computing device, thereby producing the simulation of the subject-specific blood flow of the heart, wherein a target edge length is set to be a mean of a current edge length.
