Abstract: The present invention proposes an electromagnetic (EM) tracking technology that can be used to track devices with embedded EM sensors over time. If these objects move too fast, tracking signals are lost because of the motion induced potential differences. It is therefore proposed to add a processing mechanism incorporating additional processing algorithms to enable tracking of the EM sensors. An embodiment of the invention is for performing biopsies using a biopsy gun. The additional processing algorithms incorporate dedicated prior information on the expected signal obtained from the embedded EM sensor and are introduced to allow processing the signals from the moving sensors. The prior information can be incorporated in a heuristic or statistical model to process the EM signal.

Abstract: The present invention relates to a medical intervention system which increases the safety of the patient or animal during a medical intervention comprising a needle insertion step. This object is achieved by a medical intervention system as claimed in claim for use during a medical intervention, comprising: a needle guide configured to guide needle insertion into a body for a medical intervention wherein the needle guide comprises restriction means for regulating the needle insertion resistance wherein the needle guide comprises an actuator configured for operating the restriction means in dependence of an input control signal and a medical data unit configured for storing and/or acquiring medical data; a control system, configured for receiving data from the medical data unit further configured to generate the input control signal for the restriction means based on the medical data in order to reduce the risk of penetration of a vulnerable area by the needle.
