ROI Calculation Logic

Assuming a 20% average reduction in surgical time for complex internal procedures. For a hospital performing 20 surgeries per month, with an average cost of $5K (AI est.) per surgery (750,000 JPY / 150), this could result in a monthly cost reduction of $10K (AI est.) (1,500,000 JPY / 150), totaling $120K (AI est.) annually (18,000,000 JPY / 150). Additionally, a 5% reduction in complication rates could save an estimated $80K (AI est.) (12,000,000 JPY / 150) annually in re-operations and additional treatments, leading to a total economic impact of ~$200K/year (AI est.).
