SYSTEM FOR ACQUIRING ULTRASOUND IMAGES OF AN ORGAN OF A HUMAN BODY
A system for acquiring ultrasound images of an organ of a human body comprises a scanner and at least one inertial measurement unit (IMU) associated therewith.
Method and apparatus for pulmonary interventions
Apparatus and methods for deactivating bronchial nerves extending along the secondary bronchial branches of a mammalian subject to treat asthma and related conditions. An ultrasonic transducer (11) is inserted into the bronchus as, for example, by advancing the distal end of a catheter (10) bearing the transducer into the secondary bronchial section to be treated. The ultrasonic transducer emits circumferential ultrasound so as to heat tissues throughout circular impact volume (13) as, for example, at least about 1 cm.sup.3 encompassing the bronchus to a temperature sufficient to inactivate nerve conduction but insufficient to cause rapid ablation or necrosis of the tissues. The treatment can be performed without locating or focusing on individual bronchial nerves. The apparatus and methods utilized for lung tumor ablation.
DEVICE AND METHOD FOR MEASURING THE VISCOELASTIC PROPERTIES OF A VISCOELASTIC MEDIUM
A device for vibration controlled transient elastography, in particular to quantify liver fibrosis, includes an ultrasound probe for elastography comprising a probe casing, at least one ultrasound transducer having a symmetry axis, a vibrator, and a force sensor, wherein the vibrator is arranged to induce a movement of the probe casing along the symmetry axis of the ultrasound transducer, the ultrasound transducer being bound to the probe casing with no motion of the ultrasound transducer relative to the probe casing, and wherein the device includes a signal generator configured to issue a contact ready signal when the force applied by the probe on the to-be-measured viscoelastic medium is greater than a minimum contact force threshold. The signal generator may further be configured to issue a measurement ready signal when the force is greater than a minimum measurement force threshold.
Fully automatic ultrasonic scanner and scan detection method
A fully automatic ultrasonic scanner and a scan detection method is provided. The fully automatic ultrasonic scanner comprises: an ultrasonic probe (4); a driving system (5) for driving the ultrasonic probe (4) to move; and a flexible structure on which the ultrasonic probe (4) is mounted, wherein the flexible structure enables the ultrasonic probe (4) to be always along a curve of a skin surface and keep perpendicular to the skin surface during scanning. The flexible structure of the fully automatic ultrasonic scanner has self-adaptive effect, can adjust the scan trace and the probe angle in real time according to different curves of the human body, and ensure that the ultrasonic probe (4) scans against the skin surface and keeps perpendicular to the skin surface, which improves the quality of the scanned images, so as to enhance the detection rate and accuracy rate of early screening, and reduces the probability of missed diagnosis.
IDENTIFYING A BODY PART
A computer-implemented method of identifying a subject's body part on which a hand-held device is used to perform a personal care operation. The hand-held device comprises a head portion for contacting the subject's skin one or more sensors for measuring a parameter and generating measurement signals as the hand-held device is used on the subject's skin. The sensor(s) comprise(s) at least one of a skin contact sensor, skin tone sensor, and/or proximity sensor. The method includes obtaining a measurement signal from each sensor; analyzing the obtained measurement signal using a trained machine learning model (MLM) to identify the subject's body part that the hand-held device is used on. The trained MLM analyzes a plurality of measurements in a time window on each of the obtained measurement signals to identify the body part. An indication of the identified body part is then outputted.
Multi-modal ultrasound probe for calibration-free cuff-less evaluation of blood pressure
A system for calibration-free cuff-less evaluation of blood pressure is proposed. The system includes an ultrasound-based arterial compliance probes and a controller unit connected to the said probe. The ultrasound transducers measure the change in arterial dimensions, pulse wave velocity, and other character traits of an arterial segment over continuous cardiac cycle, which is then used to evaluate blood pressure parameters without any calibration procedure using dedicated mathematical models. The pressure sensor/force sensor/biopotential transducers/accelerometric sensors measure a pressure acting on a skin surface at a measurement site, an internal arterial transmural pressure level, an applied pressure or a hold-down pressure on the skin surface or an arterial site, biopotential and/or plethysmograph signal, arterial vibrations acting on the measurement site as a function of the arterial pressure and the mechanical characteristics and/or a function of the applied/hold-down pressure and/or function of external factors.
