Abstract: A system comprising synchronization circuitry, a first interrogator, and a second interrogator. The first interrogator includes a transmit antenna; a first receive antenna, and circuitry configured to generate, using radio-frequency (RF) signal synthesis information received from the synchronization circuitry, a first RF signal for transmission by the transmit antenna, and generate, using the first RF signal and a second RF signal received from a target device by the first receive antenna, a first mixed RF signal indicative of a distance between the first interrogator and the target device. The second interrogator includes a second receive antenna, and circuitry configured to generate, using the RF signal synthesis information, a third RF signal; and generate, using the third RF signal and a fourth RF signal received from the target device by the second receive antenna, a second mixed RF signal indicative of a distance between the second interrogator and the target device.

Abstract: Systems and methods for facilitating interactions between a medical device (e.g., an imaging device, a surgical tool, a robotic arm, etc.) and a patient using radio frequency (RF) co-localization are provided. The systems include a radio-frequency (RF) interrogator system, one or more first RF target devices for coupling to a patient support for supporting a patient with respect to whom a medical device is to perform a task, and one or more second RF target devices for coupling to the medical device. A controller determines a position of the patient support within an RF interrogator system reference frame, a first position of the medical device within the RF interrogator system reference frame, a transformation between the RF interrogator system reference frame and a patient support reference frame, and a second position of the medical device within the patient support reference frame.

Abstract: Radio-frequencies (RF) antennas for use in micro-localization systems are described. The RF antennas described herein may enable localization of objects with high resolutions, such as in the order of one centimeter or less. The RF antennas may be further configured to reduce range error variability across different directions, so that the accuracy of a micro-localization system is substantially the same regardless of the position of the object. An illustrative RF antenna includes an emitting element having first and second conductive traces patterned to reduce the angular impulse delay variability of the RF antenna. The first conductive trace may form a first arm of a spiral and the second conductive trace may form a second arm of the spiral. At least one parameter of the spiral may be selected to reduce the angular impulse delay variability of the RF antenna.

Abstract: A system and method is disclosed for measuring time of flight to an object. A transmitter transmits an electromagnetic signal and provides a reference signal corresponding to the electromagnetic signal. A receiver receives the electromagnetic signal and provides a response signal corresponding to the received electromagnetic signal. A detection circuit is configured to determine a time of flight between the transmitter and the receiver based upon the reference signal and the response signal.
