Methods and systems for modulation and mapping of brain tissue in a subject using an ultrasound assembly are provided. An exemplary method for modulation uses an ultrasound assembly including a housing and an ultrasound transducer joined to the housing. The method includes securing the housing to the head of the subject with the ultrasound transducer aligned with a region of the brain tissue to target the region of the brain tissue for modulating, and providing focused ultrasound at an acoustic pressure to the targeted region using the ultrasound transducer to induce cavitation proximate the targeted region. The method further includes detecting a cavitation signal magnitude from the induced cavitation corresponding to the acoustic pressure and modulating the targeted region.

The disclosed ultrasound devices may include at least one ultrasound transmitter positioned and configured to transmit ultrasound signals toward a user's face to reflect off a facial feature of the user's face and at least one ultrasound receiver positioned and configured to receive and detect the ultrasound signals reflected off the facial feature. At least one processor may be configured to receive data from the at least one ultrasound receiver and to determine, based on the received data from the at least one ultrasound receiver, at least one of the following eye measurements: an interpupillary distance of the user; an eye relief; or a position of a head-mounted display relative to the facial feature of the user. Various other devices, systems, and methods are also disclosed.

Disclosed is a peroral endoscopic apparatus of a swallowable type, the peroral endoscopic apparatus including: at least one imaging unit configured to perform imaging of a human body digestive system and output image data; at least one ultrasonic unit configured to output ultrasonic data on a submucosal region of the digestive system and a peripheral organ located therearound; a magnetic unit configured to adjust a position, a posture, and a proceeding direction of the peroral endoscopic apparatus in response to an external magnetic force; a transceiving unit configured to transmit the image data and the ultrasonic data to an external device or receive an external control signal; a control unit configured to control the imaging unit and the ultrasonic unit to perform imaging of the digestive system and the submucosal region simultaneously or individually; and a power supply unit configured to supply power.

A puncture assistance system provides information on a collapse state of a blood vessel to be punctured, caused by pressing action of an ultrasonic probe, when ultrasonic images of the blood vessel are acquired. A puncture assistance system 10 includes: vascular diameter detecting means 18 for detecting a vascular diameter during acquisition of the ultrasonic images from an ultrasonic diagnostic device 11; puncture assistance information generating means 12 for generating puncture assistance information for determination of whether or not puncture is allowed to be performed based on a collapse state of a blood vessel B caused by pressing action of an ultrasonic probe 15 against skin S by comparing a current vascular diameter detected by the vascular diameter detecting means 18 with a standard vascular diameter stored in advance; and a monitor 19 that presents the puncture assistance information.

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 apparatus includes a sensor which guides a decision that acoustic coupling quality is insufficient, the apparatus issuing a user alert upon the decision.

A system and method is provided for obtaining ultrasound images of an interior of an object that includes an image processing unit that receives and processes acquired ultrasound scan data to create ultrasound images derived from ultrasound image data, a motion detection system configured to detect a pattern of inactivity time frames within movement cycles of the object and an ultrasound imaging probe operably connected to the image processing unit to acquire the ultrasound scan data for use by the image processing unit to form the ultrasound images. The motion detection system detects a pattern of one or more inactivity time frames within a first cycle of movement of the object, obtains ultrasound volumetric scan data of the object during the inactivity time frame within a second cycle of movement of the object, and calibrates a location of a scan plane of the ultrasound image within the volumetric ultrasound image.

A craniofacial implant includes a craniofacial implant body and a passive pressure sensor. The craniofacial implant body permits measurement of the passive pressure sensor via externally applied stimuli passing through the craniofacial implant body.

An elastography device includes a probe with a single ultrasound transducer; or a plurality of ultrasound transducers, and a low frequency vibrator arranged to induce a displacement of said single ultrasound transducer or plurality of ultrasound transducers towards a tissue. The device is configured to emit a sequence of ultrasound pulses and to acquire echo signals received in response to track how elastic waves, induced by the displacement, travel in the tissue. The device is configured to generate, for one or more of the ultrasound pulses emitted a temporal offset upon emission, and/or a temporal offset upon reception, so that a difference thereof varies as a function of 2.d/.sub.Vus, where d is the displacement of the single transducer or plurality of ultrasound transducers, and where .sub.Vus is the speed of ultrasound in said tissue.

An exemplary system includes a memory storing instructions and a processor communicatively coupled to the memory. The processor may be configured to execute the instructions to: detect an intent of a user of a computer-assisted surgical system to use a robotic instrument attached to the computer-assisted surgical system to interact with a target object while the target object is located in a surgical space; determine a pose of the target object in the surgical space; and perform, based on the detected intent of the user to interact with the target object and the determined pose of the target object in the surgical space, an operation with respect to the target object.

An ultrasound device includes an ultrasound body having a shaft and an ultrasound sensor assembly disposed at a distal end portion of the shaft. The ultrasound sensor assembly is configured to enable ultrasound imaging. A clip is configured for positioning about a portion of a surgical tool. The clip is configured to releasably engage the ultrasound body to thereby releasably couple the surgical tool with the ultrasound body. A surgical system includes the ultrasound device and the surgical tool.
