Experience |
Carnegie Mellon University, Medical Robotics and
Computer Assisted Surgery Lab |
Pittsburgh, PA |
|
|
Developed an algorithm to create synthetic X-rays from 3D CT data used to register real postoperative X-rays to preoperative 3D CT data sets. Used the registration technique to find the orientation of implants following total hip replacement surgery (THR). Developed an algorithm that registered live arthroscopic images to generic 3D surface models to build 3D image mosaics. Created a tool for planning the implant orientation for THR surgery using preoperative X-rays and templates for the implants. Developed software suite to plan and perform live fluoroscopic THR surgery. Supervised numerous undergraduate researchers. |

|
As a key member of the AMTS project, worked on vision systems of an automated forktruck. Developed navigation system combining dead reckoning with downward vision for more accurate navigation. Implemented a look-up table to eliminate lens distortion in downward vision system. Developed a pallet tracker based on a kinematic model of the vehicle, capable of loading and unloading a trailer and stacking pallets. Overcame 2 cm resolution in fork positioning to achieve 1 cm accuracy in translation and 0.01 radian accuracy in rotation required for successful pallet stacking. Developed path planning routines and point generator which produced points in the path to be executed. Collaborated with NASA on 3D simulation of automated plant. Supervised 2 undergraduates. |
