The experimental schematic of the setup used to perform the transcranial histotripsy clot treatments through the excised human skullcaps (left) a photograph of the actual experimental setup (right). The 256 individual elements of the array were triggered one-at-a-time, to emit histotripsy pulses. Waveforms were measured by the catheter hydrophone (CH) uploaded to an aberration correction algorithm. The 256 element delays were obtained uploaded to the FPGA boards.
