What iMedical does

iMedical Inc. (株式会社iMedical) is a Tokyo-based private healthcare technology company founded in June 2013 that operates one of Japan's largest remote image diagnosis (teleradiology) platforms. The company's core offering enables medical institutions to transfer CT, MRI, PET, mammography, X-ray, and ultrasound images to a contracted network of over 100 certified radiology specialists, who return diagnostic reports with a standard next-business-day turnaround and an emergency reading option. iMedical also provides Holter ECG analysis, 12-lead ECG interpretation, and clinical-trial QT waveform measurement, and operates mepo, a dedicated web reservation system for health screening and complete medical examinations with auto-integration to customer health screening management systems.

The business is built around three revenue streams: per-study and subscription-based teleradiology reading (including the 2024-launched zero-base-fee Smart Reading i-Radi ZERO product targeting low-volume facilities), usage-based Holter ECG analysis, and subscription/transaction-based mepo reservation services with free initial deployment. Distribution is primarily direct field sales targeting large hospitals, regional base hospitals, and health screening facilities, supplemented by inbound inquiries managed through inside sales, content marketing via 28+ educational columns on teleradiology topics, trade publication advertising, and presence at industry events such as ITEM2025 and the Japan Human Dock Society Academic Conference. The company holds JISQ15001:2017 personal information protection certification and integrates with hospital PACS, electronic medical records, and health checkup management systems.

iMedical acquired Diamond Medical Net from LSI Medience in December 2020 and merged the subsidiary in April 2023, making it the second-largest teleradiology operator in Japan. Strategic partnerships include NOBORI Corporation (a Mitsui-backed cloud PACS and AI imaging platform) for planned AI integration into reading workflows, and the Japan Health Insurance Association for the 協会けんぽ web reservation package on mepo. The company serves 100+ medical institutions and health screening facilities domestically, with mepo surpassing 100,000 registered users as of December 2021.
