| contents | Low-intensity focused transcranial ultrasonic stimulation (TUS) offers unique depth and precision in non-invasive brain stimulation. Effective administration of TUS, however, requires precise placement of transducers to ensure selective neural target exposure and engagement. This process is constrained by individual skull anatomy, hardware limitations, as well as computational and time costs of running exhaustive acoustic simulations to optimize transducer placement. To address these challenges, we introduce PlanTUS, a fast, open-source tool designed to heuristically identify feasible transducer positions, accounting for individual anatomical and hardware constraints. It visualizes relevant metrics on the scalp, such as target accessibility, required transducer tilt, and skull thickness, allowing users to identify and export potential transducer positions compatible with both acoustic simulation and neuronavigation software. In addition to individualized planning, PlanTUS facilitates feasibility evaluations during study planning, offering practical utility to researchers seeking to optimize TUS delivery with greater efficiency and precision. |
