Low-intensity focused ultrasound (FUS) is an emerging non-invasive and spatially/temporally precise method for modulating the firing rates and patterns of peripheral nerves. This paper describes custom body-conformal probes used within an image-guided platform for chronic and patient-specific FUS neuromodulation. The probes contain separate ultrasound imaging and modulation arrays realized using piezoelectric transducers assembled on a flexible printed circuit board (PCB). Dualmode probes operating around 4 MHz (imaging) and 1.3 MHz (modulation) were fabricated and tested on tissue phantoms. The resulting B-mode images were analyzed using a template-matching algorithm to estimate the location of the target nerve and then direct the modulation beam towards the target.
