High Intensity Focused Ultrasound (HIFU) system has been successfully applied to the tumor therapy. It is crucial to localize the tumor region accurately in this system. In this paper, a semi-automatic non-rigid registration algorithm is presented to implement the image-guided surgery navigation and localization by registration of pre-operative CT/MRI images and intra-operative US images. The global...
Cardiovascular interventions in the region of the aortic isthmus such as stent-grafting and vessel transposition introduce substantial changes in the deformation properties of the affected vessels. The changes play a fundamental role in the long-term prognosis for any such treatment, but are only poorly understood to date. We explore a fully automated method to quantify the deformation patterns of...
