Functional ultrasound imaging (fUSI) is a powerful neuroimaging technique, but building systems from scratch is complex and expensive. Researchers and enthusiasts need accessible tools to experiment with this technology.
Develop an open-source toolkit with hardware schematics, software, and detailed guides for building fUSI systems. Monetize through premium support, consulting, or advanced features.
Start with basic documentation and a simple software library. The biggest risk is the niche audience and competition from commercial solutions.
