摘要：
An electromagnetic (EM) system for tracking a surgical tool is provided. The system may comprise a plurality of subsets of field generator coils disposed along edge portions of a surgical bed. Each subset of field generator coils may be configured to generate a magnetic field within a control volume. The system may further comprise a position sensor disposed on a portion of the surgical tool. The position sensor may be configured to generate a sensor signal in response to the magnetic field when the position sensor is located inside the control volume. Additionally, the system may comprise an EM system controller configured to selectively activate one or more of the subsets of field generator coils based on the sensor signal.
