ROI Calculation Logic

Optimizing precise diagnosis and treatment planning could reduce unnecessary re-operations and shorten rehabilitation periods. For example, improving the re-operation rate by 5% for 1,000 annual surgeries (assuming an average medical cost of ~$2,500/case (AI est.)) and shortening rehabilitation by an average of 10 days (assuming ~$100/day (AI est.)) could result in an annual saving of (~$125K + ~$1M) = ~$1.1M (AI est.). Indirect benefits from reduced diagnosis time and improved patient satisfaction may also contribute.

Speed to Market
6× faster than in-house development
This technology's algorithm for generating 3D bone and cartilage shapes is already established and patented. This allows for significantly faster market entry compared to developing similar technology from scratch. It can directly utilize existing medical imaging data (CT, MRI, etc.), substantially shortening the data acquisition phase. This eliminates the time required for theoretical construction and foundational technology development, enabling rapid product commercialization and service deployment.
