“…These have to be interpreted very carefully because the study design excluded the influence of soft tissue movements, and those are supposed to have the biggest impact on precision of surface matching techniques. However, our clinical experiences as well as the numerous studies do suggest acceptable accuracy for laser surface matching (Marmulla et al, 1997a;Raabe et al, 2002;Schlaier et al, 2002;Marmulla et al, 2003;Troitzsch et al, 2003;Marmulla et al, 2004a;Marmulla et al, 2004b;Marmulla et al, 2004c;Hoffmann et al, 2005;Marmulla et al, 2005a). This technique very often does not need additional 3D imaging for surgical navigation and has no need of preoperative invasive procedures in order to prepare the patient for the computerassisted surgery.…”

BACKGROUND: Surgical navigation is a commonly used tool in cranio-maxillofacial surgery. Registration is the key element for precision, and a number of studies have shown different techniques to be accurate. Nonetheless, uncertainty surrounds the special situation in edentulous patients and a practical approach to what can be a challenging problem. MATERIALS AND METHODS: Four registration strategies for the Brainlab VectorVision(2) system are presented for surgical navigation of edentulous patients: three landmark-based, point-to-point techniques and one surface-based matching strategy are evaluated. RESULTS: The methods described differ in overall accuracy as well as in the region covered. In general, the more time-consuming and invasive the technique, the more precise it is. The non-invasive techniques are less precise, and they cover only small regions with sufficient accuracy. CONCLUSIONS: Taking into account which type of accuracy is clinically relevant and that the whole skull does not always need to be covered with the greatest possible accuracy, all the described techniques have their indications. The simpler and less invasive techniques can spare time, decrease costs, and harm patient. A decision tree is presented to the reader.

“…No specific image-data acquisition with markers for registration is necessary. The accuracy of this method is limited because superficial landmarks are not definite or reliable due to possible skin shift or swelling, and distinct marks on the bone are not always available at the site of surgery and require invasive registration 2,5,19,22,34,44,49,52,57,61,67,70,78,93,107,121,128,131,135,137,143,145,147,154,168,176,179,193,195,196 . Use of this method is described for image-guided surgery of the lateral skull base 19 , spine 78 and spinal chord 94 .…”

Abstract. This paper describes an experimental protocol in order to evaluate the accuracy oflocalizers for computer-integrated surgery (CIS), and the result of the evaluation for four commercially available optical localizers (Optotrak, FP5000 , Polaris active and passive). This paper shows that the four systems have static xyz accuracy compatible with most of CIS applications, but they significantly differ when comparing their accuracy of moving rigid bodies. IntroductionIn CIS, the six degrees of freedom (6D) localization is used to locate and follow in space the position and orientation of rigid bodies constituted of markers, with respect to a reference rigid body. For example, a localizer can be used to track the tip and the axis of a pointer or surgical tool on pre-operative images (after registration) or to digitize landmarks or surfaces on anatomical structures to track the position of the sensor such as an ultrasound probe, or to measure the relative positions of bones [1, 2, 3], An extensive list of commercial products existing for localization can be found in [4,5], but few of them meet the CIS requirements in terms of accuracy (about lmm in lm3), reliability, clinical usability... Four technologies have been used in CIS :Mechanical technology : Mechanical loealizers such as Viewing-Wands TM use a 6-axes coding robot-arm [6,7]. The main problem of this technology is the global clutter if we need to locate more than one rigid body. Magnetical technology : Magnetical localizers such as Polhemus TM orFlocks-of-Birds TM use a magnetic source and a receiver of magnetic fields [8]. The problem of this technology is the relative inaccuracy due to metallic objects. At least, those systems imply to use non-ferromagnetic objects in the environment.Acoustical technology : Acoustical localizers such as Pegasus TM measure the time of/light between emitters and receivers in order to get distance information. Unfortunately, measurements are sensitive to several perturbation such as air movements, parasite reflexions, temperature gradients in space and time f9].Optical technology : In this category ther are the most usefull localizers
