A method of assessing the likelihood that an infected subject develops sepsis, using an input radiofrequency signal received from the subject responsively to an output radiofrequency signal transmitted to the subject. The method comprises: processing the input signal to provide a processed signal, analyzing the processed signal to determine a characteristic pulse morphology of the processed signal, and using the characteristic pulse morphology for assessing the likelihood that the subject develops sepsis.

A method includes determining, by a computer processor coupled to memory, data associated with a patient, the data comprising a heart rate value, a peak velocity through aortic valve value, and a stroke volume value; generating a flow waveform for the patient using the data; determining a set of candidate vascular impedance (VI) values for the patient based at least in part on the flow waveform, the set of candidate VI values comprising first and second VI values; determining a first pressure waveform using the flow waveform and the first VI value; determining a second pressure waveform using the flow waveform and the second VI value; determining a blood pressure value for the patient; determining that the first pressure waveform is a closer match to the blood pressure value than the second pressure waveform; and determining that the patient has a vascular impedance of the first VI value.

Method and apparatus for non-invasive condition detection using an all fiber portable terahertz imaging system. An imaging system of the present disclosure may comprise a control module comprising a femtosecond pulsed laser configured to generate an output light beam, a dispersion compensation unit configured to receive the output light beam and transmit a laser light beam generated based upon the output light beam, a beam splitter configured to receive the laser light beam and divide the laser light beam into a pump light beam and a reference light beam; and a rapid scanning optical delay line configured to receive the pump light beam and transmit an exit light beam generated based upon the pump light beam, a patch probe comprising a transmitter module, an optics lens, and a detector module.

Disclosed herein are systems and methods for revascularization assessment. The methods can in some cases include one or more of the steps of measuring blood perfusion as a function of time to obtain time series data, mathematically transforming the time series data into a power spectrum, calculating at least one parameter of the power spectrum within a specific frequency range, and using the at least one calculated parameter as a discriminator for the first population and the second population.

A three-dimensional morphological vessel model (20) can be obtained by assigning diameters (14,15) along the vessel derived from a two-dimensional morphological projection (10) at locations in the three-dimensional model defined by the temporal locations (21,22) of a trackable instrument (5). An apparatus (7), a system (1) and a method (100) for use of the system (1) in characterizing the vessel of a living being (2) by rendering a three-5 dimensional morphological vessel model (20) are presented.
