ROI Calculation Logic

For example, consider the time and cost associated with tissue extraction and pathological examination in hospitals. If a hospital currently incurs a cost of ~$350/case (AI est.) for 10 examinations per day, and this technology improves preparation time and process efficiency by 20%, an annual cost reduction of approximately ~$190K (AI est.) could be realized ($350/case × 10 cases/day × 20 days/month × 12 months × 0.2 = ~$190K/year). Additionally, factoring in savings from labeling probe costs, reduced maintenance for large equipment, and new market creation in biometrics, an annual economic impact exceeding ~$0.5M (AI est.) is anticipated.

Speed to Market
4× faster than in-house development
The fundamental principles of the optical system using optical waveguides are established, and the core algorithms for recording interference fringes from biological tissues and subsequent computer-based image processing are already built. This could shorten development time by approximately 3 years compared to a licensee developing similar technology from scratch. The core technology for high-precision, non-invasive biological information acquisition is patent-protected, significantly reducing time-to-market and enabling early competitive advantage.
