Brain tissue strain could be a valuable source of information on the brains tissue properties. Therefore, accurate DENSE measurements are crucial, since the computation of tissue strain requires spatial derivatives, which amplifies noise present in the displacement maps. In this work, we optimize the SNR in the displacement maps and substantiate the theory with both computer simulations and measurements. We tested the optimized settings in one volunteer and found a factor of 1.66 SNR increase compared to previously reported experiments. Preliminary results in one volunteer in the basal ganglia showed heartbeat-induced strain of approximately 2.1·10-3 and inspiration-induced strain of -0.54·10-3.
