Abstract
Systems and methods for marking the location and extent of an anatomical region-of-interest, such as a tumor, using magnetic seeds whose position and orientation are measured or otherwise detected using a detection device that includes two or more magnetic sensors are described. One or more magnetic seeds are implanted to mark and define the center and extent of an anatomical region-of-interest and a magnetic sensor-based detector system is used to accurately identify the location of the magnetic seeds.

A method for localizing a marker, comprising:
- generating, by a first magnetic sensor of a detector apparatus and a second magnetic sensor of the detector apparatus, signal data representative of the magnetic field generated by the marker, wherein the first magnetic sensor is proximal to the second magnetic sensor and an operative sensor axis of the first magnetic sensor is not parallel with an operative sensor axis of the second magnetic sensor;
- processing, by at least one processor, the signal data generated by the first magnetic sensor and the second magnetic sensor to determine a location of the marker;
- and
- providing an output based on the determined location of the marker.
An apparatus for localizing a marker, comprising:
- a first magnetic sensor;
- and
- a second magnetic sensor located distally of the first magnetic sensor, wherein an operative sensor axis of the second magnetic sensor is non-parallel with an operative sensor axis of the first magnetic sensor, wherein the first magnetic sensor and the second magnetic sensor are configured to detect the magnetic field generated by the marker and in response thereto generate signal data representative of the magnetic field.
A kit for localization of an implantable marker, comprising:
- a detector apparatus comprising:
- a first magnetic sensor, and
- a second magnetic sensor located distally of the first magnetic sensor, wherein an operative sensor axis of the second magnetic sensor is non-parallel with an operative sensor axis of the first magnetic sensor,
- wherein the first magnetic sensor and the second magnetic sensor are configured to detect a magnetic field associated with the marker and in response thereto generate signal data representative of the magnetic field.
