BACKGROUND New hardware and software algorithms in electromagnetic tracking for computer assisted surgery (CAS) have been developed. We aimed to compare electromagnetic tracking for navigated procedures in frontal skull base surgery to optical tracking. METHODS Target registration error (TRE) was determined in 6 anatomic specimens in an experimental(More)
BACKGROUND Navigation with optical tracking sometimes makes it difficult to establish a line-of-sight in cluttered operating theatres. On the other hand, the accuracy of electromagnetic tracking is influenced by ferromagnetic surgical equipment. We compared electromagnetic with optical tracking under controlled conditions for the lateral skull base. (More)
BACKGROUND AND OBJECTIVES During navigated procedures a tracked pointing device is used to define target structures in the patient to visualize its position in a registered radiologic data set. When working with endoscopes in minimal invasive procedures, the target region is often difficult to reach and changing instruments is disturbing in a challenging,(More)
