HIRAC FUND has invested in Precision Imaging. The startup develops an AI navigation system for artificial hip joint replacement. The investment came from HIRAC FUND's second fund, managed by Money Forward Venture Partners.


Why the fund invested

HIRAC FUND highlighted CEO Seiya Ishii's clinical experience and product approach. He spent more than 10 years working on artificial joint research and surgical support devices. The fund also cited the company's patents and accelerator program selections.

Company background

Precision Imaging was founded on September 1, 2023. Its headquarters are in Tokyo's Chuo ward. Ishii graduated from Juntendo University's medical school in 2012 and later worked at its university hospital.

How the system works

The system uses AI trained on CT images to read fluoroscopy during surgery. It estimates cup position, angle, and depth in three dimensions in real time. The tool works with mobile X-ray devices already used in hospitals.


HIRAC FUND will provide access to its regional bank network and business development knowledge. It will also support fundraising and hiring. Precision Imaging will use the investment to speed development toward clinical use.
