‘Pre-operative image-to-patient registration using patient-specific instruments’

One of major issues in a conventional arthroscopic system is limited field-of-view (FOV). This constrains surgeons’ perspective regarding the orientation of an instrument in a surgical space as well as hand-eye coordination in arthroscopic surgery. Therefore, inexperienced surgeons require a lot of arthroscopic surgeries for their better perspective. This research aims to solve the issue by image processing called panorama.


Image-to-patient registration is prerequisite step for implementing a surgical navigation system in the operating room, but it takes much time to complete the step.
As the development of 3-D printing technology, it became easier to manufacture complex 3-D structures such as organs of human.
Through the 3-D printing technology, our group developed patient-specific instruments (PSI), which is possible to be installed on the surface of the hard tissues such as spinous process (spine).
Thanks to this PSI, the intraoperative registration time could be significantly reduced.
