Multiple-correlation similarity for block-matching based fast CT to ultrasound registration in liver interventions

Computed tomography (CT) is a popular diagnostic imaging technique with high image resolution and, due to fast imaging speed, few motion artifacts. Vessels are not always clearly visible in CT. To image blood vessels, scans are performed after the administration of contrast material. With matrix array probes ultrasound (US) provides real-time 3D imaging. 2D US imaging is used as an intraoperative imaging modality, e.g. in thermal ablation tumor therapy. However, tumors are not always clearly visible in US.
