Figure 4:Measurement geometry.The black strips represent current-injecting electrodes,and the red dots depict the tips of the
recording electrodes.The dashed green arrow is the ultrasound beam axis and the solid blue arrow represents the current..
Figure 5:Experiment timing during parameter sweep.As seen in Figure 2,a trigger pulse from the HP33120A signal generator is sent
to an FPGA,which triggers the ultrasound pulse such that it coincides either with the current maxima or minima.
Figure 6:Experiment timing.As seen in Figure 2,a trigger pulse from the HP33120A signal generator is sent to an FPGA which
triggers the ultrasound pulse and the data acquisition after a variable delay.The delay is controlled via a parallel port from a computer
