Probes and related systems and methods are provided for localizing markers implanted within a patient's body. The probe includes an antenna assembly adjacent a distal end thereof including a ceramic base including a planar distal surface and four proximal surfaces extending at an angle relative to a longitudinal axis of the probe to define a generally pyramidal shape. The base includes antenna elements on the proximal surfaces and radial slots between adjacent proximal surfaces to substantially isolate the antenna elements from one another. A controller is coupled to the antenna elements for transmitting signals into a patient's body and receiving reflected signals reflected from a marker implanted within the patient's body to identify and/or localize the marker.

Systems and methods for localizing markers within a body

Markers and related systems and methods are provided for localizing lesions within a patient's body, e.g., within a breast. The marker includes one or more photosensitive diodes for transforming light pulses striking the marker into electrical energy, one or more antennas, and a switch coupled to the photodiodes and antennas such that the light pulses cause the switch to open and close and modulate radar signals reflected by the marker back to a source of the signals. The antenna(s) may include one or more wire elements extending from a housing, one or more antenna elements printed on a substrate, or one or more chip antennas. Optionally, the marker may include a processor coupled to the photodiodes for identifying signals in the light pulses or one or more coatings or filters to allow selective activation of the marker.
