Numerical Simulation of Double Wave Vector Diffusion Experiments

Double wave vector (DWV) diffusion weighting might provide a means to acquire information on cell size and shape. In numerical simulations we test a theoretical description of the DWV signal in a situation where the approximating assumptions are not strictly met. We show how the dependence of the signal on the angle between the diffusion gradient directions changes upon variation of the waiting period between 2nd and 3rd gradient pulse. This is done to consolidate seemingly contradicting experimental results concerning the angle at which the largest signal attenuation occurs.
