A method for monitoring a health parameter in a person is disclosed. The method involves transmitting radio waves below the skin surface of a person and across a range of stepped frequencies, receiving radio waves on a two-dimensional array of receive antennas, the received radio waves including a reflected portion of the transmitted radio waves across the range of stepped frequencies, generating data that corresponds to the received radio waves, wherein the data includes amplitude and phase data, deriving data from at least one of the amplitude and phase data, and determining a value that is indicative of a health parameter in the person in response to the derived data.

A pulse measurement device is provided, including a first signal source, a second signal source, two microwave resonators, two mixers, and a signal processing unit. The first signal source and the second signal source output a first high-frequency signal and a second high-frequency signal, respectively. Each of the microwave resonators generates an electric field according to the first high-frequency signal, and senses a variation in the electric field which is interfered by a pulse to obtain a sensing signal. Each of the mixers is coupled to one of the microwave resonators, to mix the sensing signal and the second high-frequency signal to output a down-converted signal. The signal processing unit respectively demodulates amplitudes of the down-converted signals of the two mixers to obtain amplitude signals.

A detection device for detecting and characterizing biological energy fields emitted by biological specimens is configured to collect and analyze an electromagnetic signal that includes millimeter-length waves generated by the interaction of atmospheric plasma with torsion waves of the biological energy field. The device performs spectral analysis on the millimeter waves to determine characteristics of the corresponding torsion waves that generated them. An array of several hundred non-thermal plasma plumes are placed directly in front of a circular horn. A switchable circular polarizer is used to select left hand circular, linear or right hand circular polarization. A low noise frequency converter allows a noise temperature of less than 1150 K. A frequency scan and averaging algorithm is developed to characterize noise temperature versus frequency, comparing signal and noise levels between plasma on and plasma off, and switching polarization sense.

Apparatus, systems, and methods are provided for localization of a needle within a patient's body using markers. In an exemplary embodiment, a probe includes a distal end for placement against a surface of the region and one or more antennas for transmitting electromagnetic signals into and receiving reflected signals from the region.

In one embodiment, the system receives medical imaging data of a patient, as well as connected implant data from an implant device implanted in the patient. A number of features are extracted via artificial intelligence (AI) algorithms from the medical imaging data and connected implant data. One or more reports are then generated based on the extracted features. In some embodiments, the systems and methods provide for indices, features, information, and/or metrics which have clinical value, and which enable a surgeon to support his or her decisions (related to, e.g., diagnosis, prognosis, monitoring, or any other suitable subject area).
