A method to measure Inflow Velocity Density of brain tissue based on velocity selective ASL is proposed. The method uses modified BIR-8 pulses to generate both cosine and sine velocity dependent profiles in the observed magnetization. Fourier analysis of the resulting data yields the distribution of flow velocities in the arterial blood supply to a given voxel.
