Anatomical landmarks for point-matching registration in image-guided neurosurgery

Abstract

The AL configurations proposed in this investigation provide sufficient registration accuracy and can help to avoid the disadvantages of SMs if used clinically.

Development of instrumentation for neuronavigation and transcranial magnetic stimulation

“…The obtained values are in the range of those reported in the literature for several navigation systems (Kuehn et al, 2008;Omara et al, 2014;Ruohonen and Karhu, 2010). Even though the FRE is primarily used to indicate the accuracy of the navigation procedure its interpretation is limited to the quality of registration procedure and fiducial points (Fitzpatrick et al, 1998).…”

“…The potential to grasp and inspect details of the actual anatomy can aid surgeons to plan complex operations, aiming better patient prognosis. Furthermore, the InVesalius Navigator software enabled realtime localization and digitization of anatomical structures with measurement errors within limits provided by literature for clinical practice, i. e., below 3 mm (Kuehn et al, 2008;Omara et al, 2014). The combined use of 3D-printed models and neuronavigation might allow practicing and simulation of the whole surgical procedure in advance.…”

Electromagnetic navigation-guided surgery in the semi-sitting position for posterior fossa tumours: a safety and feasibility study

“…Electromagnetic (EM) navigation was introduced more than a decade ago in neurosurgery, but in contrast to optoelectric navigation it has gained more widespread recognition only recently [7,10,11,15,19,24,27]. It has certain advantages over opto-electric navigation; in particular, there are no line-of-sight problems.…”

Towards estimating fiducial localization error of point-based registration in image-guided neurosurgery

“…For example, in image-guided surgery, this technique can be used to track the navigation tools, register images with different modalities, register the patient space to the image space and serve as an initialization step in surface based patient-to-image registration [1][2][3][4][5]. The point-based registration problem can be solved analytically [6], but the two coordinate systems cannot be registered perfectly because of the imperfectness of the correspondence.…”
