Fast calibration of electromagnetically tracked oblique-viewing rigid endoscopes
International Journal of Computer Assisted Radiology and Surgery, 2017The oblique-viewing (i.e., angled) rigid endoscope is a commonly used tool in conventional endoscopic surgeries. The relative rotation between its two moveable parts, the telescope and the camera head, creates a rotation offset between the actual and the projection of an object in the camera image.

Awake craniotomy using electromagnetic navigation technology without rigid pin fixation
Journal of Clinical Neuroscience, 2015We report our institutional experience using an electromagnetic navigation system, without rigid head fixation, for awake craniotomy patients. The StealthStation® S7 AxiEM™ navigation system (Medtronic, Inc.) was used for this technique. Detailed preoperative clinical and neuropsychological evaluations, patient education and contrast-enhanced MRI ...

Electromagnetic scattering by fully ordered and quasi-random rigid particulate samples
Journal of the Optical Society of America A, 2016In this paper we have analyzed circumstances under which a rigid particulate sample can behave optically as a true discrete random medium consisting of particles randomly moving relative to each other during measurement. To this end, we applied the numerically exact superposition T-matrix method to model far-field scattering characteristics of fully ...

Electromagnetic field-current coupling in rigid polarized conductors
Mathematics and Mechanics of Solids, 2016A continuum model, based on a theory of electromagnetic media with microstructure, is exploited to deal with rigid conductors endowed with polarization and magnetization. Charge carriers are considered as a continuum superimposed to the microstructured conductor where the density of bound charges depends on the internal degrees of freedom of the ...

Electromagnetic forces in three-phase rigid busbars with rectangular cross-sections
IEEE Transactions on Power Delivery, 1996A three-phase busbar arrangement with straight rigid conductors carrying short-circuit currents is investigated. Calculations are made assuming steady-state AC current with a peak value equal to the peak value of the short-circuit current. This assumption is used in the related IEC Standards 865/92. In this paper, the electromagnetic forces and current
