摘要： An example method is performed by a single medical device and includes detecting, during a time interval, a sound indicative of cardiac activity of a subject; generating audio indicative of a pulse of the subject by analyzing the sound; and simultaneously outputting: the audio indicative of the pulse of the subject; and a visual signal indicating an additional physiological parameter of the subject detected during the time interval.

摘要： An ultrasound imaging system (100) may automatically analyze a pulse wave Doppler spectrogram to determine high quality and low quality cardiac cycles. Based on the determination, the ultrasound imaging system (100) may exclude the low quality cardiac cycle from being used in calculations of parameter measurements such as peak systolic velocity, end diastolic velocity, and resistance index. In some examples, the ultrasound imaging system (100) may provide a visual indication on the display (138) which cardiac cycles were excluded from the measurements.

摘要： An enhanced stethoscope device and method for operating the enhanced stethoscope are provided. The enhanced stethoscope device generally operates by providing stethoscope sensors, ultrasonic sensors, and other sensors to obtain a series of measurements about a subject. The series of measurements may be correlated, such as by machine learning, to extract clinically relevant information. Also described are systems and methods for ultrasonic beamsteering by interference of an audio signal with an ultrasonic signal.

摘要： An ultrasound system (10) includes a single transducer (14). The single transducer (14) includes a flexible substrate (48). The single transducer (14) also includes an array of transducer elements (52) disposed on the flexible substrate (48) and configured to be disposed on an abdomen of a subject having one or more fetuses disposed within a single uterus and to acquire scan data. The ultrasound system (10) also includes a processor (44) coupled to the single transducer (14) and configured to receive the scan data and to determine a respective fetal heart rate of each fetus of the one or more fetuses based on the scan data.

摘要： The present invention relates to flow measurement in a vessel. In order to provide a facilitated and less complex determination of the average peak velocity based solely on a plurality of ultrasound signals, a device (10) for flow measurement in a vessel is provided that comprises a data input (12), a processor (14) and an output interface (16). The data input is configured to provide a plurality of ultrasound signals that relate to blood flow within the vessel. The processor is configured to generate blood flow velocity data based on the plurality of ultrasound signals; to detect a measure for similarity or variation based on the plurality of ultrasound signals; to ascertain a pulse rate based on the detected measure for similarity or variation; and to compute, based on the estimated pulse rate, an average parameter value for a blood flow parameter, which blood flow parameter is generated from the plurality of ultrasound signals. The output interface is configured to provide the average parameter value to a user for further assessment.

摘要： La présente description concerne un dispositif électronique portable d'évaluation d'activité cardiovasculaire humaine, comprenant des première et deuxième sondes sensiblement parallèles entre elles et situées de part et d'autre d'une troisième sonde (101C), sensiblement perpendiculaire aux première et deuxième sondes, chaque sonde comportant une barrette de transducteurs ultrasonores (103A, 103B, 103C), et un circuit de commande configuré pour :
a) estimer, par un premier faisceau ultrasonores émis par la première sonde (101A), une position d'un vaisseau sanguin (150) par rapport au dispositif ; et
b) ajuster un deuxième faisceau ultrasonore (201 ; 201'), émis par la troisième sonde (101C), en fonction de la position estimée du vaisseau sanguin (150).
