Abstract

A dual imaging endoscopic probe, comprising: (a) a probe body having a proximal end and a distal end at opposite ends of a probe axis; (b) a first imaging module operable in an MRI imaging modality and including a main field magnet located on the probe body; and (c) a second imaging module operable in a ultrasound imaging modality and located on the body at a fixed relative position and orientation with respect to the first imaging module; wherein a field of view of the first imaging module and a field of view of the second imaging module are at a known rotational and/or axial displacement from one another.
