Volumetric Electromagnetic Phase Shift Spectroscopy (VEPS)-based methods of analyzing a tissue are provided. Aspects of the methods comprise obtaining a VEPS-based tissue classifier, or “signature” for a tissue at a single point in time. These methods find particular use in non-invasively determining the condition of a tissue, e.g. brain tissue, lung tissue, heart tissue, muscle tissue, skin tissue, kidney tissue, cornea tissue, liver tissue, abdomen tissue, head tissue, leg tissue, arm tissue, pelvis tissue, chest tissue, trunk tissue, prostate tissue, breast tissue, esophagus tissue, GI tract tissue, etc., in an individual. Devices and systems thereof that find use in practicing the subject methods are also provided.

A method of determining volumetric data of a predetermined anatomical feature is described. The method comprising determining volumetric data of one or more anatomical features present in a field of view of a depth sensing camera apparatus, identifying a predetermined anatomical feature as being present in the field of view of the depth sensing camera apparatus, associating the volumetric data of one of the one or more anatomical features with the identified predetermined anatomical feature, and outputting the volumetric data of the predetermined anatomical feature. An apparatus is also described.

In one example, a method of estimating lung fluid content includes receiving a first response signal in response to a delivered first test stimulus, the first test stimulus delivered and the first response signal obtained during a first subject state, receiving a first estimate of a fluid content value during the first subject state, receiving a second response signal in response to a delivered second test stimulus, the second test stimulus delivered and the second response signal obtained during a second subject state, receiving a second estimate of the fluid content value during the second subject state, pairing the first response signal and the first estimate of the fluid content value to form a first pair of values and pairing the second response signal and the second estimate of the fluid content value to form a second pair of values, and determining a relationship between the pairs of values.

A system and method for monitoring lung water content of a patient. The system may include microwave sensors and a processor. The system may transmit microwave signals into, and receive microwave signals from, the thorax of a patient using the microwave sensors. The received microwave signals may each have at least one frequency component with a magnitude and a phase. The system may analyze the phase of the received microwave signal corresponding to a first pair of the microwave signals to monitor changes in the lung water content. The system may analyze the magnitude of the received microwave signal corresponding to a second, different pair of the microwave sensors to determine whether the lung water content is increasing or decreasing. The system may also analyze the received microwave signals to determine a blood pressure indicator and to determine lung water content.

A method for detecting evidence of a stroke in a patient may involve securing a volumetric integral phase-shift spectroscopy (VIPS) device to the patient's head, transmitting a first signal from a first transmitter of the VIPS device through a left hemisphere of the patient's brain to a receiver of the VIPS device, transmitting a second signal from a second transmitter of the VIPS device through a right hemisphere of the patient's brain to the receiver, and detecting the evidence of the stroke, with the VIPS device.

A method and device for measuring intra-abdominal pressure in a pregnant woman to assess likelihood or occurrence of pre-eclampsia. The method includes providing a catheter having first and second lumens and a balloon, inserting the catheter into a bladder of the patient, injecting gas into the first lumen of the catheter to expand the balloon, obtaining a first pressure reading of the bladder based on deformation of the balloon to thereby monitor pressure within an abdomen of the mother to assess if pre-eclampsia is occurring or likely to occur and transmitting the first pressure reading to an external monitor connected to the catheter. The pressure reading is indicative of the presence and/or risk of pre-eclampsia to determine when intervention should occur to prevent morbidity and mortality of the woman and baby.

An apparatus for monitoring for accumulation of lung fluid comprises a feeding tube having first electrode(s) positioned thereon for electrical contact with tissue of an esophagus of a target patient including a lower esophageal sphincter (LES) and/or tissue in proximity to the LES, second electrode(s) sized and shaped for contacting skin of the target patient, and a non-transitory memory having stored thereon code instructions for applying alternating current(s) to pair(s) of first and second electrodes, measuring a voltage over the pair(s), and computing an estimate of a change of lung fluid relative to a baseline in lung(s) of the target patient according to the applied alternating current and measured voltage, wherein the applying, the measuring, and the computing the estimate of the change in lung fluid are iteratively executed for monitoring the target patient for accumulation of lung fluid while the feeding tube is in use.

The present disclosure provides apparatuses and methods for measuring capacitance as an indication of susceptibility to the formation of a diabetic foot ulcer.

Methods for estimating of the effectiveness of catheter ablation procedures to form lesions, and particular lesions which together form an ablation segment of an ablation line. Lesion effectiveness parameters are received, and effectiveness, optionally the joint effectiveness, of corresponding ablations (optionally planned, current, and/or already performed) is estimated. In some embodiments, estimating is based on use by computer circuitry of an estimator constructed based on observed associations between previously analyzed lesion effectiveness parameters, and observed lesion effectiveness. Additionally or alternatively, estimators may be constructed based on analytic functions. The estimator is used by application to the received lesion effectiveness parameters.
