Abstract
A detection system for detection of surgical implements within a body of a patient, includes a magnetic field generator configured to generate a magnetic field, a sensor configured to sense a distortion in the magnetic field in response to an approximation of the sensor to a surgical implement, a processor, and a memory. The memory includes instructions stored thereon, which, when executed by the processor, cause the system to: generate a directional magnetic field within a surgical site by the magnetic field generator; sense a distortion in the magnetic field using the sensor; and determine a presence of the surgical implement in response to the sensed distortion in the directional magnetic field.
