3D Rigid Registration of Intraoperative Ultrasound and Preoperative MR Brain Images Based on Hyperechogenic Structures

Figure 5

Patient 1. Left: registration given by the neuronavigation system. Right: the result after correction with our registration approach. The low intensities of US images are in green and the high in red. For this case, even if the lesion was not entirely included in the US volume, the proposed registration procedure converged. The location of the lesion is indicated by ellipses on the fused image after registration.
