Establishing image context is the major difficulty of performing laparoscopic ultrasound. The standard techniques used by
transabdominal ultrasonographers to understand image orientation are difficult to apply with laparoscopic instruments. In
this paper, we describe a navigation system that displays the position and orientation of laparoscopic ultrasound images to
the operating surgeon in real time. The display technique we developed for showing the orientation information uses a D model
of the aorta as the main visual reference. This technique is helpful because it provides surgeons with important spatial cues,
which we show improves their ability to interpret the laparoscopic ultrasound.

    • "The first navigation system for laparoscopic surgery in the abdomen was presented by Ellsmere et al. [11]. The goal of this system was not to support hepatic surgery, but rather to improve the orientation in the use of laparoscopic (2D) ultrasound by visualization of the ultrasonic level in relation to the aorta and the large abdominal arteries.

    ABSTRACT: Laparoscopic liver resection has been performed mostly in centers with an extended expertise in both hepatobiliary and laparoscopic surgery and only in highly selected patients. In order to overcome the obstacles of this technique through improved intraoperative visualization we developed a laparoscopic navigation system (LapAssistent) to register pre-operatively reconstructed three-dimensional CT or MRI scans within the intra-operative field. After experimental development of the navigation system, we commenced with the clinical use of navigation-assisted laparoscopic liver surgery in January 2010. In this paper we report the technical aspects of the navigation system and the clinical use in one patient with a large benign adenoma. Preoperative planning data were calculated by Fraunhofer MeVis Bremen, Germany. After calibration of the system including camera, laparoscopic instruments, and the intraoperative ultrasound scanner we registered the surface of the liver. Applying the navigated ultrasound the preoperatively planned resection plane was then overlain with the patient's liver. The laparoscopic navigation system could be used under sterile conditions and it was possible to register and visualize the preoperatively planned resection plane. These first results now have to be validated and certified in a larger patient collective. A nationwide prospective multicenter study (ProNavic I) has been conducted and launched.

    • "Kawamata et al. [76] visualize the anatomical context by drawing virtual objects in a larger area of the screen than endoscope images are available. Ellsmere and colleagues [77] suggest augmenting laparoscopic ultrasound images into CT slices and using segmented CT data for improved context sensing. "

    ABSTRACT: The impressive development of medical imaging technology during the last decades provided physicians with an increasing amount of patient specific anatomical and functional data. In addition, the increasing use of non-ionizing real-time imaging, in particular ultrasound and optical imaging, during surgical procedures created the need for design and development of new visualization and display technology allowing physicians to take full advantage of rich sources of heterogeneous preoperative and intraoperative data. During 90's, medical augmented reality was proposed as a paradigm bringing new visualization and interaction solutions into perspective. This paper not only reviews the related literature but also establishes the relationship between subsets of this body of work in medical augmented reality. It finally discusses the remaining challenges for this young and active multidisciplinary research community.

    • "Several high quality, low cost, portable (battery powered or low power) instruments are now commercially available, creating the opportunity to design such a system for portable casualty care. However, since ultrasound imaging requires a level of care and sophistication that makes it unlikely that a minimally Compact Anatomically Guided Ultrasound for Casualty Care Barnabas Takacs and Kirby G. Vosburgh F trained, unsupported operator could perform a diagnostic examination under field conditions, tools for 3D visualization, guidance and telemedicine using the toolset of Image Guided Surgery become a necessity [2].

    ABSTRACT: We present a 3D anatomically guided diagnostic system to detect internal bleeding of patients in the field. Our solution employs high fidelity digital human models to help medics with minimal training to find anatomical structures and subsequently obtain high quality ultrasound scans that may be shared with doctors located remotely.
