  • Patent number: 11266375
    Abstract: The invention relates to determining a fetal heart rate from an ultrasonic Doppler echo signal. Rather than extracting the Doppler signal from the carrier signal using synchronous demodulation, quadrature demodulation is used, which allows to distinguish between systolic and diastolic movements. This velocity direction can be used to cut out unwanted parts of the signal (systolic or diastolic heart activity), thus eliminating double counting heart rates. In particular, a binary sign signal (15?) may be used to cut out unwanted signal episodes, resulting in a processed reference signal (10?) having only the signal parts of one heart activity. Another aspect relates to determining a first and a second heart rate from at least two channels having a different depth range, and selecting one of the first and second heart rate based on external information of the fetal or maternal heart rate.

The processing apparatus comprises a model subtraction circuit configured to receive the physiological signal and to reduce a first unwanted signal component, such as an ECG contamination, in the physiological signal by subtracting from the physiological signal a model of the first unwanted signal component to obtain a residual signal; a filter circuit configured to receive the residual signal and to reduce a second unwanted signal component, such as power line noise, in the residual signal by applying a notch filter to obtain a filtered signal; and a gating circuit configured to receive the filtered signal and to apply gating to the filtered signal to obtain a gated signal. The processing apparatus further relates to a corresponding electromyography system and a method for processing a physiological signal using model subtraction, notch filtering and gating.

  • Patent number: 11051768
    Abstract: Systems and methods are provided for evaluating an alarm condition for a monitored patient in a population of one or more patients. One or more physiological parameters pertaining to the patient, or physiological variables, are used to form a time series describing the patient status. A dimension parameter such as a time series roughness statistic or a fractal dimension is used to estimate a dimension decision statistic over time. The dimension decision statistic is used as a measure of physiological condition. The dimension decision statistic may be compared to a threshold to determine a region of operation for the dimension of the physiological variable. The dimension decision statistic is used in an embodiment in combination with the underlying raw physiological variable value to reduce the rate of false alarms, to increase the frequency of missed detections, and to aid diagnostic decision making and to aid the formation of a crisis action plan.

  • Patent number: 11035919
    Abstract: Magnetic resonance compressed sensing data may be acquired and reconstructed into an image. Noise-like aliasing present in the compressed sensing data may be modeled. The reconstruction may include denoising the compressed sensing data based on a noise level of the compressed sensing data, a sampling density of the compressed sensing data, and the model of the noise-like aliasing. A result of the denoising is denoised image data. The reconstruction may further include generating updated image data based on the compressed sensing data and the denoised image data. An output image based on the updated image may be output.

  • Patent number: 10959669
    Abstract: Systems and methods for performing and assessing neuromodulation therapy are disclosed herein. One method for assessing the efficacy of neuromodulation therapy includes positioning a neuromodulation catheter at a target site within a renal blood vessel of a human patient and delivering neuromodulation energy at the target site with the neuromodulation catheter. The method can further include obtaining a measurement related to a dimension of the renal blood vessel via a sensing element of the neuromodulation catheter. The measurement can be compared to a baseline measurement related to the dimension of the renal blood vessel to assess the efficacy of the neuromodulation therapy. In some embodiments, the baseline measurement is obtained via the sensing element of the neuromodulation catheter prior to delivering the neuromodulation energy.

  • Patent number: 10939848
    Abstract: A method and apparatus are disclosed for assessing a respiratory function from plethysmography data obtainable, for example, from a pulse oximeter. A pulsatile waveform obtained from pleth data is processed to obtain a second waveform extending over a over multiple respiratory cycles and representing respiration-related variations in a pulse-beat area defined by the pulsatile waveform. The second waveform is analyzed to obtain information indicative of respiratory distress. A respiratory index that provides a good indicator of respiratory distress may be computed based on a magnitude of respiratory peaks in the second waveform. Applications to asthma and sleep apnea are described.
