A recently granted patent (Publication Number: US11883150B2) describes a system for localizing a target tissue region within a patient's body using a probe with antennas and markers implanted in the body. The markers, equipped with energy converters and clock circuits, generate code sequences to modulate electromagnetic signals reflected by them. These code sequences are orthogonal to each other, allowing for precise identification and localization of each marker by the probe's processor. The system utilizes light pulses and power harvesting blocks to operate the markers and synchronize their activities, ensuring accurate and simultaneous tracking of multiple markers within the patient's body.

Furthermore, the patent details the configuration of the markers, including energy converters, power harvesting blocks, clock circuits, elongate members for antennas, and sequence generators. The markers generate orthogonal code sequences to open and close switches in a synchronized pattern, aiding in the modulation of reflected electromagnetic signals. The system's processor can separate and analyze the reflected signals from the markers based on these code sequences, providing information on distances and locations of the markers. By utilizing infrared light pulses and ultrawide band radar pulses, along with advanced signal processing techniques, the system offers a comprehensive solution for precise localization of target tissue regions within a patient's body, enhancing the accuracy and efficiency of medical procedures.
