Synopsis

Keywords: Phantoms, Velocity & Flow, SimulationThe lattice Boltzmann method (LBM) is a versatile technique to simulate fluid dynamics in complex environments. We extended the LBM to flows with a spin 1/2 degree of freedom in external magnetic fields. We performed 3D simulations for FLASH MRI of a laminar flow in a pipe and the complex flow of the Karman vortex street.
