A dynamic headset system is provided. The dynamic headset system includes a head cradle configured to receive a head of a subject and having a bottom surface configured to face a platform on which the dynamic headset apparatus is placed. The dynamic headset system further includes a device including an instrument adjacent to the head of the subject when the head of the subject is in the head cradle.

Arrangements described herein relate to systems, apparatuses, and methods for managing gel on a subject to provide gel on a first area of the subject, including controlling a transducer to move to a second area of the subject and controlling the transducer to move the gel to the first area from the second area.

A dynamic headset system is provided. The dynamic headset system includes a head cradle configured to receive a head of a subject and having a bottom surface configured to face a platform on which the dynamic headset apparatus is placed. The dynamic headset system further includes a device including an instrument adjacent to the head of the subject when the head of the subject is in the head cradle.

A method for convection-enhanced delivery (CED) of compounds and an apparatus for use with the method are provided. The apparatus, an ultrasound transducer cannula assembly (TCA) apparatus, can be used for the delivery of a compound to a target in the body such as a cells, tissue or organ in a healthy or diseased state. The ultrasound TCA apparatus comprises a transducer cannula assembly (TCA) and an ultrasound system to enhance penetration of molecules in the target. The ultrasound system may be portable and pocket-sized. The inclusion of ultrasound in the apparatus improves the distribution volume of material four to six times over a convection-enhanced delivery system without ultrasound. Since the targeting can be more focused, less compound is needed, thus lowering the potential for harmful effects to the host and host cells.

An ultrasound probe holding device configured to attach to the head of an infant for transfontanellar imaging is disclosed, including a head pad configured to be in contact with the head of the infant and including a central opening, wherein the head pad is configured to receive an ultrasound probe; a pad squeezer, including a central opening and configured to cooperate with the head pad to allow an axial guidance of the head pad along a guidance axis substantially perpendicular to a surface tangent to the head of the infant; a device holder configured to be attached to the head of the infant and exert a downward force on the pad squeezer, along said guidance axis; and a repellent configured to exert a repellent force between the pad squeezer and the head pad when the device holder exerts the downward force on the pad squeezer.

A method may include positioning a catheter, including at least one electrode, within an esophagus such that the electrode is proximate to at least one sympathetic ganglion. The methods may further include recruiting the sympathetic ganglion via an electrical signal, monitoring the recruitment of the sympathetic ganglion, and, based on the monitoring the recruitment of the sympathetic ganglion, adjusting the electrical signal from the at least one electrode.

The present disclosure describes a therapeutic ultrasound system configured to adaptively transmit ultrasound pulses toward microbubbles in a treatment region to remove an occlusion. In some examples, the system may include a treatment pulse unit configured to transmit an ultrasound pulse to a treatment region of a subject, the treatment region including a plurality of microbubbles. An echo detection unit may be configured to receive one or more echoes responsive to the ultra sound pulse. In some examples, the system may also include a data processor configured to identify, using data associated with the echoes, at least one echo signature indicative of a dynamic state of the microbubbles in response to the ultrasound pulse. A controller may be configured to adjust one or more parameters of an additional ultrasound pulse transmitted to the treatment region via the treatment pulse unit based on the at least one echo signature.

Skull inhomogeneity may be quantified in accordance with the skull density measured in skull images acquired using a conventional imager; the quantified inhomogeneity may then be used to determine whether the patient is suitable for ultrasound treatment and/or determine parameters associated with the ultrasound transducer for optimizing transskull ultrasound treatment.

A dynamic headset system is provided. The dynamic headset system includes a head cradle configured to receive a head of a subject and having a bottom surface configured to face a platform on which the dynamic headset apparatus is placed. The dynamic headset system further includes a device including an instrument adjacent to the head of the subject when the head of the subject is in the head cradle.

A tool for facilitating medical diagnosis is disclosed herein, including an ultrasound device configured to collect ultrasound data from a patient, a display device, and a processing circuit configured to generate a cerebral blood flow velocity (CBFV) waveform based on the ultrasound data, determine morphology indicators identifying attributes of the CBFV waveform, and configure the display device to display the CBFV waveform and the morphology indicators.
