A real-time navigation system for laparoscopic surgery based on three-dimensional ultrasound using magneto-optic hybrid tracking configuration

Abstract: Objectives In laparoscopic liver surgery, intraoperative navigation is strongly recommended. We developed a navigation system based on intraoperative ultrasound (IOUS). The purpose of this study was to evaluate the usefulness and accuracy of this system using an animate model. Materials and methods Augmented reality (AR) visualization superimposing three-dimensional ultrasound (3D-US) images onto captured laparoscopic live images was constructed. We employed magneto-optic hybrid tracking configuration and a ra… Show more

“…An optical tracking system was used for registration between volume image and body surface markers. A rigid body with optical markers was attached to the camera head for measuring its six degrees of freedom pose parameters using an optical tracker, and the rotary encoder was geared to the scope cylinder for measuring its rotation parameters [9,10]. Afterwards, directions of laparoscopic views were calculated.…”

“…(Marescaux et al, 2004;Mutter et al, 2010;Nozaki et al, 2012;Pratt et al, 2012)) proposed manual alignment of pre-operatively and intra-operatively acquired images. The majority of (semi-) automatic approaches for registering the endoscopic image data with 3D anatomical data acquired pre-or intra-operatively are either marker-based (Baumhauer et al, 2008;Falk et al, 2005;Ieiri et al, 2011;Marvik et al, 2004;Megali et al, 2008;Mourgues et al, 2003;Simpfendorfer et al, 2011;Suzuki et al, 2008) or use external tracking devices that are initially calibrated with respect to the imaging modality (Ukimura and Gill, 2008;Konishi et al, 2007;Shekhar et al, 2010;Feuerstein et al, 2008;Konishi et al, 2007;Feuerstein et al, 2007;Leven et al, 2005;Blackall et al, 2000)). In an alternative approach, reconstructed surface data may be used to perform the registration with pre-operative models (Audette et al, 2000).…”

“…Various navigation approaches for laparoscopic liver interventions integrate laparoscopic ultrasound (LUS) for partial liver resection [84], [59], [60] and laparoscopic radio frequency ablation (RFA) [47], [62], [4]. In this context, a flexible laparoscopic 2D ultrasound probe is commonly used, and electromagnetic tracking sensors are utilized to reconstruct a 3D volume dataset [43], [123] or even a 4D volume over time [83] from freehand 2D measurements.…”

“…A trend of recently developed navigation systems is the combined use of optical and magnetic tracking devices within a hybrid magneto-optic tracking configuration, reported first by Birkfellner et al [9] and later on for laparoscopic interventions by Nakamoto et al [84], Konishi et al [60], and Feuerstein et al [32]. This assembly of tracking methods allows the navigation systems to benefit of the advantages of both techniques.…”
