3D Rigid Registration of Intraoperative Ultrasound and Preoperative MR Brain Images Based on Hyperechogenic Structures
Figure 3
Patient 2. (a) The denoised MR image corresponding to US image (b). (c) The probability map based on operator and extracted from denoising MR image. The preoperative MR image is resliced with the registration matrix provided by the neuronavigation system. The matching is not perfect due to the initial error, estimated around 8.5 mm by the experts for this patient. The red box shows a sulcal area where the matching between US image and the -based probability map is visually high. A large acoustic shadow is visible in US around the ventricle area (indicated in orange on the US image).
