The invention provides device for detecting potential sinus pathologies, comprising a patch (310), comprising one or more vibration sensing devices (320), configured to be placed on facial bones overlying a sinus of a subject, wherein the patch is configured to obtain facial bone vibration signals generated due to vibrations in facial bones surrounding the sinus, wherein characteristics of the facial bone vibration signals are representative of condition of the sinus. The device further comprises a processing subsystem operationally coupled to the patch and configured to: receive the facial bone vibration signals from the patch during vocalization of sounds by the subject, resulting in resonant frequency vibrations of the facial bones; and determine a physiological measure of the sinus of the subject based on characteristics of the facial bone vibration signals received during said vocalization of sounds by the subject, wherein the facial bone vibration signals comprise the resonant frequency vibrations.

A method for analyzing physical features of an individual comprises directing an acoustic signal toward a mouth of the individual, receiving a reflected acoustic signal from the interior of the mouth of the individual, generating a structural profile of at least the interior of the mouth of the individual based at least in part on the reflected acoustic signal, and causing an action to be performed in response to generating the structural profile. The acoustic signal is configured to reflect off at least a portion of the interior of the mouth of the individual. The reflected acoustic signal is indicative of structural characteristics of the mouth of the individual. The structural profile can also be based on image data associated with the exterior of the head and neck of the individual, and image data associated with the interior of the mouth of the individual.

The present invention presents an apparatus and methods to guide insertion of invasive devices to a tissue target of a living body. The apparatus comprises a positioning guide control assembly and a positioning guide assembly that is operably detachable from the control assembly, and rotationally adjustable and lockable. The positioning guide control assembly releasably houses a ultrasound transducer head and measures an insertion length and an insertion angle of an invasive device placed in the positioning guide assembly to reach the tissue target.

An ultrasound probe and an ultrasound system are disclosed. In some embodiments, the ultrasound probe includes a probe body having a user interface with controls and a mode selector.

Systems and methods are disclosed related to using acoustic waves to detect neural activity in a brain and/or localize the neural activity in the brain. Sensors positioned outside of a skull encasing the brain can detect acoustic waves associated with the neural activity in the brain. From output signals of the sensors, a particular type of neural activity (e.g., a seizure) can be detected. A location of the neural activity can be determined based on outputs of the sensors. In some embodiments, the ultrasound energy can be applied to the location of the neural activity in response to detecting the neural activity.

An ultrasound system including: a scanner module including a housing including a first fastener element, an ultrasound transducer, a rotational actuator, and an electronics module; and a positioner module including a second fastener element; operable between a first mode, wherein the first and second fastener elements cooperatively couple the scanner module to the positioner module, and a second mode, wherein the scanner module and positioner modules are separate. An ultrasound system including: a housing including a handle region and a membrane; an ultrasound transducer; a reservoir; a rotational actuator; and an electronics module.

An ultrasound diagnostic apparatus includes an ultrasound image acquirer, an evaluation target determiner, a disease progression score calculator, a selector, and a display controller. The ultrasound image acquirer acquires ultrasound image signals of a plurality of frames. The evaluation target determiner analyzes the ultrasound image signal of each frame and determines the frame to be an evaluation target frame when the ultrasound image signal includes a target image section depicting a joint. The disease progression score calculator calculates, for each evaluation target frame, a disease progression score quantifying disease activity using an ultrasound image signal of the target image section included in the ultrasound image signal of the evaluation target frame. The selector selects at least one disease progression score in accordance with a predetermined numerical process. The display controller controls the display to display the selected disease progression score and an ultrasound image of a corresponding frame.

In some embodiments, the probe structure further includes a plurality of fingers adapted to extend outwards from the probe body. In some embodiments, the probe structure further includes a spring including a plurality of coils adapted to wrap around the probe body and compressed between a compression plane and probe body. In some embodiments, the end coil of the plurality of coils is configured to encircle the plurality of fingers. In some embodiments, the compression plane is a grip held by a human operator. In some embodiments, the compression plane is a robotic end effector that positions itself over any topography.

A device for assisting with the handling of an instrument or tool, the device comprising a jointed mechanical structure on a support, wherein an instrument or tool may be attached, motor drives configured to actuate the jointed mechanical structure, according to a number of degrees of freedom of less than that which the structure provides to the instrument or tool, and an automatic control, wherein the automatic control drives the motor drives in order to facilitate the meeting of a constraint on position and/or velocity parameters of the instrument or tool, which constraint the motor drives by themselves, independently of handling by an operator, cannot entirely meet.
