Experimental method for measuring the targeting accuracy of the neuronavigation-guided FUS in a water tank. (A) Setup used to calibrate the location of FUS transducer geometrical focus to the BrainSight system using a calibration block provided by BrainSight (left). The FUS transducer was inserted tightly into a 3D-printed cap (right). The cap was tightly inserted to the pin on the calibration block. (B) Experimental setup for measuring the targeting accuracy in a water tank. Position of the FUS transducer relative to the tank was tracked with BrainSight based on CT images of the water tank. The acoustic pressure fields generated by the FUS transducer was measured with a hydrophone mounted on a 3D motor stage. (C) Fiducial marker placement on the water tank.
