Ultrasound Guided Surgery: Image Processing and Navigation

The process of 3D freehand ultrasound acquisition consists of two steps: scanning and reconstruction. Prior to scanning, a position sensor is attached to the probe for tagging each image with its position and orientation in space. A crucial step prior to reconstruction and visualization is calibration of the ultrasound probe with the attached position sensor, i.e. determining the position and o...

Safety of Interactive Image-Guided Surgery

Augmented reality: 3D image-guided surgery

Background Over the last three decades, surgical practice has undergone a significant change with a move towards minimally invasive surgery (MIS) as the standard of care [1]. Although this has brought with it significant benefits, problems have also been associated with the advent of MIS. Perhaps the most substantial limitation associated with MIS is the loss of haptic feedback; this deficit is...

Surface Registration for Use in Interactive Image-Guided Liver Surgery

OBJECTIVE Liver surgery is difficult because of limited external landmarks, significant vascularity, and inexact definition of intra-hepatic anatomy. Intra-operative ultrasound (IOUS) has been widely used in an attempt to overcome these difficulties, but is limited by its two-dimensional nature, inter-user variability, and image obliteration with ablative or resectional techniques. Because the ...
