Searching for optimal needle insertion path by intraoperative magnetic resonance imaging (MRI) is complex and time-consuming task in MR-guided microwave thermotherapy of liver tumor. This paper reports the semi-active needle-guiding robot for MR-guided therapy by which a surgeon can freely selects needle insertion path while maintaining the remote center of(More)
Fast image registration for magnetic resonance image (MRI)-guided surgery using projection profile matching embedded in MR pulse sequence is proposed. The method can perform two-dimensional image registration by matching projection profiles acquired with zero-degree phase encoding. The matching process continuously measures displacement by optimizing cross(More)
