  Regularized optimal mass transport (rOMT) problem adds a diffusion term to
the continuity equation in the original dynamic formulation of the optimal mass
transport (OMT) problem proposed by Benamou and Brenier. We show that the rOMT
model serves as a powerful tool in computational fluid dynamics (CFD) for
visualizing fluid flows in the glymphatic system. In the present work, we
describe how to modify the previous numerical method for efficient
implementation, resulting in a significant reduction in computational runtime.
Numerical results applied to synthetic and real-data are provided.
