About
MICSI is a United States-based medical imaging technology company — backed by Y Combinator with $1.49 million raised from Graphene Ventures, NVO Capital, NYU Entrepreneurial Institute, Orange Collective, and Pioneer Fund — providing hospitals, radiology centers, and healthcare providers with the MICSI-RMT software (FDA-cleared July 2024), a Microstructure Imaging algorithm that analyzes standard MRI scanner data to generate higher-resolution tissue microstructure images and enable faster scan protocols, projecting $2 million in additional annual revenue per MRI scanner deployment for healthcare customers through improved diagnostic throughput and imaging quality. MICSI's technology works as a software overlay on existing MRI hardware — requiring no capital equipment purchase — making it deployable across the 35,000+ installed clinical MRI scanners in the United States.
