Techniques for modulating peripheral nerves using focused ultrasound (FUS) are provided. Methods include locating a peripheral nerve in a subject using an imaging probe, providing a FUS having one or more ultrasound parameters to a location on the peripheral nerve, and modulating the peripheral nerve. The methods can further include eliciting and measuring a physiological response from the FUS modulation, generating tissue deformation in the vicinity of the FUS modulation, and imaging the nerve and the tissue deformation simultaneously with FUS modulation. Systems for use in the modulation of peripheral nerves are also provided.

The embodiments herein provide a system for calibration-free cuff-less evaluation of blood pressure. The system includes an ultrasound-based arterial compliance probes and a controller unit connected to the said probe. The ultrasound transducers are configured to 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/bio-potential transducers/accelerometric sensors are configured to 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.

An image data adjustment method comprises: acquiring three-dimensional ultrasound volume data of a detected target organism; extracting first section image data, at a first position, in the three-dimensional ultrasound volume data; when an adjustment instruction output by an adjustment portion is acquired, acquiring a prediction path corresponding to the first section image data; adjusting the first position in the three-dimensional ultrasound volume data to a second position along the prediction path; and acquiring second section image data, at the second position, in the three-dimensional ultrasound volume data, and displaying the second section image data.

A holder facility for holding a medical instrument includes a first receiving element, a second receiving element, and at least three diaphragm elements. The at least three diaphragm elements within a diaphragm layer are arranged between the first and second receiving elements about a common rotation axis. The first and second receiving elements each have an opening for receiving the medical instrument. The first and second receiving elements are movable around about the common rotation axis relative to one another. Each of the at least three diaphragm elements is forcibly moved by mechanical coupling. For a movement of the first receiving element relative to the second receiving element about the common rotation axis, there is a forcibly-guided movement of the at least three diaphragm elements such that the at least three diaphragm elements hold a medical instrument arranged in the opening of the first and second receiving elements.

Aspects of the technology described herein relate to providing feedback a user to position an ultrasound device. Some embodiments include configuring the ultrasound device to alternate collection of ultrasound images having one image plane and collection of ultrasound images having the other image plane, and providing feedback to the user to position the ultrasound device based on the ultrasound images. In such embodiments, feedback may be provided for simultaneously centering the anatomical structure in both types of ultrasound images. Some embodiments include collecting ultrasound images having one image plane, providing feedback for centering the anatomical structure in those ultrasound images, and once the anatomical structure is centered in those ultrasound images, collecting ultrasound images having another image plane and providing feedback for centering the anatomical structure in those ultrasound images.

A Ring-Arrayed Forward-viewing (RAF) ultrasound imaging and administration device combines an ultrasonic (US) US imager including a plurality of single element transducers arranged in a circular frame to define a ring array, and an instrument posture tracking circuit coupled to the ring array for performing RF (radio frequency) data acquisition with the plurality of ring-arrayed transducers. A needle holster is concentrically disposed in the ring array and is adapted to receive and direct an insertion instrument such as a needle, probe or extraction tool along an axis defined by a center of the ring array directed by the concentric needle holster. The tracking circuit includes a processor having instructions for instrument posture tracking and US imaging.

A method for non-invasive detection of ingested medication which provide for one or more processors to receive images of medications designated for a user prior to ingestion of the medications by the user. The one or more processors capture an ultrasound image during ingestion by the user by an ultrasound device removably adhered to a throat area of the user. The one or more processors determine whether contents of the ingestion by the user includes one or more of the medications designated for the user, and responsive to determining the contents of the ingestion by the user includes one or more of the medications designated for the user, the one or more processors generate a confirmation that includes identification of the detected medications ingested by the user.

An ultrasound imaging system for guiding a user to acquire ultrasound image data sets that can be analyzed for the presence of atherosclerosis. In one embodiment, the processor is programmed to analyze ultrasound image data for a vessel of interest and to control a user interface that suggests how an operator should move a transducer to acquire ultrasound image data with the vessel of interest in a desired location. The processor stores multiple ultrasound image data sets taken along a length of the vessel of interest to be analyzed for the presence of an atheroma.

A treatment head (20, 20) includes an ultrasound imaging probe (22) which generates a sonogram (24) of internal anatomy of a subject (25), and a HIFU transducer 26 which emits HIFU energy (31) into the subject. A chair (28) includes a chair-frame (30) and a seat (32). When the subject is sitting in the chair, a perineum (34) of the subject is acoustically coupled to the treatment head. Control circuitry (36) (a) controls movement of the treatment head relative to the seat, (b) operates the ultrasound imaging probe to generate at least one sonogram of internal anatomy of the subject through the perineum of the subject, and (c) operates the HIFU transducer to emit HIFU energy into the body of the subject through the perineum of the subject. Other embodiments are also described.

An apparatus includes an imaging probe and is configured for dynamically arranging presentation of visual feedback for guiding manual adjustment, via the probe, of a location, and orientation, associated with the probe. The arranging is selectively based on comparisons between fields of view of the probe and respective results of segmenting image data acquired via the probe. In an embodiment, the feedback does not include a grayscale depiction of the image data. Coordinate system transformations corresponding to respective comparisons may be computed. The selecting may be based upon and dynamically responsive to content of imaging being dynamically acquired via the probe.
