Tracking Deformable Organs in Three Dimensions

Minimally invasive surgical procedures are currently the preferred approach for various reasons such as less postoperative pain, a shorter hospital stay, a faster recovery and, in some cases, a better overall outcome. In many cases, however, the efficacy of the procedure relies on the expertise of the surgeon due to the limited visual information available. Accurate real-time three-dimensional visual information of deforming organs under surgery would improve the overall efficiency of these procedures and good results would be surgeon-independent. This project attempts to achieve this goal by developing novel signal processing algorithms for reconstruction of organs in real-time at sub-nyquist sampling.
