Feasibility of transcranial MR-guided histotripsy for an in-vivo large animal model is established. Eight juvenile pigs were treated using an in-house, 128 channel histotripsy array at a wide range of sites around the brain. Target localization was done using fiducials placed on the array using pre-treatment MR images. Lesions were generated in all the pigs and were visualized in post treatment MRI scans and histology. In acute treatment phase, treatment effects were visible on T2*,T2, T1/T2 FLAIR weighted images. This is the first study to exhibit feasibility of in-vivo transcranial MR-guided histotripsy treatment.
