A therapeutic ultrasound method configured to adaptively transmit ultrasound pulses toward microbubbles in a treatment region to remove an occlusion is described. 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 ultrasound pulse. In some examples, the method 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.

Adaptive pulsing for sonothrombolysis treatment

A therapeutic ultrasound system transmits a staggered or interleaved pattern of therapy beams for use in sonothrombolysis and other Vascular Acoustic Resonators (VAR) mediated therapy. The inventive technique minimizes VAR, e.g. microbubble, destruction due to adjacent beams, ensures uniform sonication of the targeted region by filling in the spaces between the beams in subsequent passes, and further provides a means for bubble replenishment to maximize the clot lysis from ultrasound. The technique is also applicable to diagnostic ultrasound, VAR mediated drug delivery and blood brain barrier opening.

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.

It may also be based on treatment depth (). Ultrasound at the adjusted pressure setting is applied. A user interface may be provided for user entry of the estimate, the user interface being further configured for user indication of the treatment depth. Both the entered estimate and the indicated treatment depth may be used in calculating ultrasound attenuation (). The user indication can be interactive by virtue of designating, on a display, a location of a treatment target. The calculated attenuation may be a value, in decibels, that is in a range from 0.9&#xd7;(2.70&#xd7;0.1+16.60&#xd7;T+0.87&#xd7;(D&#x2212;T&#x2212;0.1)+3.02) to 1.1&#xd7;(2.70&#xd7;0.1+16.60&#xd7;T+0.87&#xd7;(D&#x2212;T&#x2212;0.1)+3.02), where T is the estimate in centimeters and D is the treatment depth in centimeters.

Ultrasonic sonothrombolysis systems to produce two acoustic pressure levels of insonation during stroke therapy, mid/high acoustic pressure insonation directed to the site of a blood clot where microbubbles are present to induce microbubble-mediated blood clot lysis, and low acoustic insonation directed to the region surrounding the site of the blood clot where microbubbles are present to stimulate microvascular reperfusion of the surrounding tissue. The systems simultaneously produce blood clot lysis at the site of an occlusion and stimulate reperfusion of tissue affected by the occlusion.

An infusion system for sonothrombolysis treatment uses a syringe loaded with a microbubble solution and operated by a syringe pump to deliver the microbubble solution to a subject during sonothrombolysis treatment. To prevent the stratification of the microbubble solution in the barrel of the syringe during treatment, the barrel also contains a plurality of magnetic beads which are agitated into semi-random patterns of motion in the syringe chamber during the procedure. The magnetic beads are moved by magnetic attraction and repulsion from the moving magnets of a magnetic stirrer mounted in proximity to the syringe during treatment.

System, apparatus and method for high-intensity focused ultrasound (HIFU) and/or ultrasound delivery while protecting critical structures

An ultrasonic intracranial sonothrombolysis pressure amplitude is pre-quantified by using an ultrasound-scanner control unit () having an increasing and/or decreasing mode and designed for: with respect to a current mode, interrogating a blockage site iteratively so as to progressively and respectively increase or decrease a pressure amplitude of ultrasound being emitted to the site at which bubbles () for oscillating that is caused by the emitted ultrasound are present; iteration to iteration, deriving, from echoes of the emitted ultrasound, a magnitude of an energy of a signal; and automatically identifying, for the quantifying, an iteration that, in comparison with a just-previous iteration, fails to increase the magnitude. The interrogating may span a region that contains or goes through: the obstruction; another part of the blood vessel; and bubble circulation within a neighboring vessel and a neighboring capillary (). The deriving can be based on an ultraharmonic signal, with band-pass filtering being utilized to extract the ultraharmonic signal from returning signals differenced to remove stationary content.

A head frame for a medical patient includes support for a probe and a neck support. The frame wraps around the head of the patient and can be used in the supine position. The support may include a probe holder slidable under the head and configured to contact or engage the neck support. In some embodiments, conformal shaping to the head and/or neck of the patient, the frame's rigid construction, the alignment of the optionally separable holder to the neck support, the weight of the head, or a combination thereof serve to keep the distal tip of the ultrasound probe in place against the temporal region of the head without need for attaching the frame to the head as by straps, which may provide an arrangement robust against patient/vehicle movement in an emergency medical services setting.
