LIFU Platform
Modular and configurable for many applications
The LIFU platform is flexible, easy-to-use, and can deliver focused ultrasound to targets nearly anywhere in the head or body. While devices are ready out of the box, the open-source design allows customization to support clinical research across diverse users and applications.
LIFU's controlled design features make it effective for developing regulated medical devices that are portable and low-cost — bridging the gap from proof-of-concept to commercially manufacturable hardware.
Hardware Platform
Three components. Infinite configurations.
A clean separation of concerns — a powerful console, a wearable transducer, and the software stack that ties it all together. Each element is documented, serviceable, and open for extension.
Console
The control brain.
Generates high-voltage drive signals (up to ±65 V), coordinates timing, and communicates with your PC over USB-C. Compact at 3 lb — fits any lab bench.
Transducer
A wearable headset.
Houses one or two 64-element 2D matrix transmit modules. Ships with a disposable hydrogel coupling pad and spatial-localization markings built in.
Software Stack
Five layers, fully open.
From 3D Slicer treatment planning to a low-level transmit-module SDK. Runs on Windows 11 with NVIDIA CUDA for real-time processing.

Research SpotlightWebinar
Transcranial Focused Ultrasound Neuromodulation of the Default Mode Network in the Treatment of Depression and Promotion of Wellness
Repetitive Negative Thinking (RNT) — including rumination and worry — is a transdiagnostic cognitive process central to major depressive disorder (MDD), generalized anxiety disorder (GAD), and obsessive-compulsive disorder (OCD). Elevated RNT is linked to increased connectivity within the brain's Default Mode Network (DMN), which is often hyperactive in these conditions.
Emerging evidence suggests that low-intensity transcranial focused ultrasound (litFUS) may reduce Repetitive Negative Thinking and mood-related symptoms in clinical populations, and also promote emotional wellness in nonclinical groups.
Open. Always.
Every schematic, open and auditable
Open-LIFU isn't a black box. Every hardware schematic, firmware file, and software layer is published and community-licensed — so you can validate, extend, and build on a foundation you actually understand.
