Regulatory Science for Medical Devices
Evaluation of medical devices to demonstrate the efficacy and the safety is the key to realize biomedical technology to use in society. Faster and clearer evaluation can be the competitiveness of the technology. We study the alternative methods to replace animal experiments and human subject trials, such as in silico clinical trial, organ models with high biofidelity.

Surgical Robotics and Standardization
In 1999 we presented world’s first MR compatible robot – robot that works while MR scanner acquires images – and we established MR compatible robotics to design, evaluate the effects between the scanner and the robot.
Chinzei currently serves as the international project leader to develop a safety standard of surgical robots under ISO and IEC.

SCC / Small Computings for Clinicals
As personal computers (PC) and smartphones evolve, software works as a medical device (SaMD) is attracting market’s focus, since it can disruptively reduce the cost from running on the custom designed hardware.
Small Computings for Clinicals (SCC) is an activity to promote innovative technology and ideas into clinical research for proof of concept. SCC’s keywords are
- Small; as small as Apple’s Mac Mini or Intel’s NUC form factor PCs.
- Single purpose; preferably a single function per single PC.
- Turn-key system; program starts by turn on the power switch, preferably UI-less.
- Low introduction cost; preferably less than 1000 USD.
SCCToolKit is an SDK to help building such application. Currently it runs on OS X… we will support Windows soon.
Biomechanics for Computer Aided Surgery
The brain, liver etc. were not the main interest of classic biomechanics, because the primal functions of these are not mechanical. However, to accurately and precisely control surgical robot or needle biopsy, one needs to predict the deformation of the organs. We started the biomechanics of such organs for surgical technology.
We presented nonlinear constitutive models of brain tissue in the strain and strain rate that practically occur in surgery. We also presented a method to detect the instance of needle insertion using a coaxial needle. Biomechanics will be an essential science for in silico clinical trial and future of autonomous surgical robots.
