Title:
外科装置の高速移動を検出する方法及びシステム
Document Type and Number:
Japanese Patent JP6557255
Kind Code:
B2
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.
