Combining Cardiac Cycles for Simulation

Post by Jessica Blair » Thu Jul 09, 2020 4:36 pm

Hello,

I am currently using CT images from a patient that represent the 10-100% of the cardiac cycle. I am hoping to create a simulation that incorporates the changing geometry of the LCA and RCA (left coronary artery and right coronary artery) for each cycle, but I am not sure how to go about doing so since they are constantly changing throughout the cycle. Is there a way to do this on SimVascular, or possibly a different way to go about doing so? I have already created paths for each of the 10-100% cycles, and will begin segmentation soon.

Thank you for your help, and stay well.

For small deformations, you'd better perform simulations with deformable walls using CMM-FSI. The CT images that record vessel motions can be used to estimate/calibrate your boundary conditions and wall properties. A complex and computationally expensive way is to directly impose the wall displacements extracted from CT images using ALE-FSI (svFSI).
