A blood pressure detection method is provided. The method comprising: obtaining wrist circumference data, wrist fat thickness data, and blood pressure data and correcting the blood pressure data based on the wrist circumference data and the wrist fat thickness data.

An ultrasound system includes: an ultrasound device having a two-dimensional array of ultrasound transducers; and a smartphone or tablet in operative communication with the ultrasound device. The ultrasound system is configured to: collect multiple sets of ultrasound data from multiple regions within the subject; detect fetal heartbeat signals and uterine contraction signals; monitor a fetal heartbeat signal among the fetal heartbeat signals by automatically steering an ultrasound beam to a first region among the multiple regions within the subject to collect first further ultrasound data from the first region based on a quality of the fetal heartbeat signal; and monitor a uterine contraction signal among the uterine contraction signals by automatically steering the ultrasound beam to a second region among the multiple regions within the subject to collect second further ultrasound data from the second region based on a quality of the uterine contraction signal.

The invention relates to a cardiotocography girdle. It is in the form of a spherical cap and comprises at least nineteen ultrasound transducers, denoted USTs, which are positioned on a first support layer (23) made of an elastic material, each UST being positioned in a support cavity (20), said girdle comprising a second support layer (24), likewise made of an elastic material and which encapsulates said USTs housed in the support cavities (20) with the first support layer (23), assembly being performed by adhesively bonding the first support layer (23) to the second support layer (24).

A graphical user interface displayed by a processing device in operative communication with an ultrasound device may include a preset filter option that provides an easy way to switch between different presets which belong to a preset family. The user uses the preset filter feature to cycle through the different presets in the family while remaining on the same screen that is showing ultrasound images collected in real time. The imaging depth remains the same while the user is using the preset filter feature to select the preset within a family. Other settings such as time-gain compensation may not remain the same when cycling between presets. The preset filter feature allows a user to continuously view and assess the ultrasound images being collected in real time while cycling through the presets in the family.

A wearable ultrasonic device constantly emitting waves attached with a readout display device includes a frame defining a space, an ultrasonic sensor, and a display panel received in the space. The ultrasonic sensor monitors a user's health. The display panel is positioned on the ultrasonic sensor. The ultrasonic sensor includes a signal transmitting layer configured to emit ultrasonic waves. The signal transmitting layer includes a second electrode layer and a plurality of piezoelectric units formed on the second electrode layer. Each piezoelectric unit includes a second piezoelectric material layer formed on the second electrode layer and a conductive layer formed on the second piezoelectric material layer.

Systems and method for destroying or inhibiting cancer cells and other rapidly-dividing cells include applying AP magnetic fields having a defined frequency of 5 Hz-500 kHz and a field strength of 0.1-5000 μT to a target body area that includes the cancer or other rapidly-dividing cells, and modifying the cancer or tumor microenvironment to increase the presence of cancer-suppressive cells or decrease the presence of cancer-promoting cells. In various embodiments, the systems and methods may include adjusting the therapy based on the dosage of an immunotherapy drug administered to the patient before, during, or after the application of the AP magnetic fields.

A guide structure (10) is configured for placement on a patient's skin and holding a medical probe (61) for adjustable positioning over the patient's skin during vascular line placement. A preferred guide structure includes a U-shaped base (12) having two arms (14, 16) separated by an open space (18). A carriage (50) for a medical probe holder (60) is movable along carriage guide surfaces (40, 42) of the arms of the base and thereby forms a movable bridge spanning the open space. The medical probe holder carrying a medical probe is movable in a direction transverse to the arms of the base to set the medical probe to a desired distance into the open space. A carriage translation actuator (62) operatively associated with the carriage enables movement of the carriage and thereby adjusts the position of the medical probe over the surface of the patient's skin.

An apparatus for estimating bio-information is provided. The apparatus includes: an ultrasound image acquirer configured to acquire ultrasound images of an object; a pressurizer configured to apply pressure to the object to occlude a blood vessel; and a processor configured to estimate a change in a diameter of the blood vessel using the ultrasound images acquired by the ultrasound image acquirer before and after an occlusion of the blood vessel, and estimate bio-information based on the estimated change in the diameter of the blood vessel.

Systems and methods for determining position and orientation of a bone of an anatomical feature are described. These include the use of a wearable holder configured to be mounted about an outer-skin surface of the anatomical feature, such that the anatomical feature and the bone are positioned in fixed relation with respect to the wearable holder when the wearable holder is mounted about the anatomical feature. Reference marker arrays are fixedly mounted to the wearable holder, each being positioned on the wearable holder to identify a landmark of the bone within the wearable holder when the wearable holder is mounted to the anatomical feature. The position and orientation of the reference markers are trackable to determine position and orientation of the wearable holder in a reference coordinate system, thereby enabling position and orientation of the landmarks on the bone to be determined.

A portable electronic device for assessing a human cardiovascular activity includes first and second probes substantially parallel to each other and located on either side of a third probe, substantially perpendicular to the first and second probes, each probe comprising an array of ultrasound transducers, and a control circuit configured to: a) estimate, by means of a first ultrasound beam emitted by the first probe, a position of a blood vessel with respect to the device; and b) adjust a second ultrasound beam, emitted by the third probe, according to the estimated position of the blood vessel.
