ROI Calculation Logic

Conventional high-precision brain function measurement devices (MEG/fMRI) can require several hundred million USD for introduction and approximately $2M/year (AI est.) in annual operating costs. Assuming this technology could reduce device and operating costs by ~66%, a direct cost reduction of ~$1.5M/year (AI est.) is expected. Additionally, improved throughput from reduced examination time could create ~$350K/year (AI est.) in revenue opportunities, totaling an estimated ~$1.5M/year (AI est.) in economic impact.

Speed to Market
4× faster than in-house development
This technology has already been demonstrated at the 'prototype' stage, with basic technical verification and validation completed. This significantly shortens the development period for adopting companies. The core principles of the magnetic field generation and detection means are established, allowing licensees to focus on application development. This could reduce development time by approximately 3 years compared to in-house development from scratch, enabling faster market entry and first-mover advantage.
