Fig. 7From: Tracked Foley catheter for motion compensation during fusion image-guided prostate procedures: a phantom studyMaximum offset distance (OD) between the phantom edge on ultrasound (US) and magnetic resonance imaging (MRI) on the axial plane. OD was defined as the distance between the phantom edge on US and perpendicular line striking the same location as seen on the contoured edge on MRI. The green contour is the pre-segmented prostate capsule from the pre-procedural MRIBack to article page
