Cramer-Rao Lower Bounds for Magnetic Localization of a Wireless Capsule Endoscope based on the Magnetic Dipole Model
In this study, wireless capsule endoscopy, which is used for imaging of the human gastrointestinal tract, is discussed. Magnetic localization technique is considered for estimating location and orientation of the capsule, owing to its potential to yield more accurate estimates. It is assumed that a cylindrical magnet wrapped around the capsule is present. The localization accuracy of this method was analyzed by Cramer-Rao lower bound method, which is alower bound on unbiased estimates. Changes in the Cramer-Rao Lower Bound were investigated under different scenarios.
