This project is to develop a fast shape-based inter-slice interpolation scheme to reduce the partial volume effect of large slice thickness while keeping less interpolation-induced blur, artifact and noise so that the subsequent segmentation, reconstruction and registration can be done with higher accuracy during TRUS/MRI fusion guided biopsy in ei-Nav/ArtermisTM . For real-time application, the GPU-based multithread (NVIDIA CUDA) programming was applied to reduce the elapsed time of this processing from hours to seconds.
