  • Method of controlling a release of a material carried by ultrasound sensitive particles
    Patent number: 8357112
    Abstract: This invention relates to a method and an apparatus of controlling a release of a material carried by ultrasound sensitive particles, the release being caused by irradiating the ultrasound sensitive particles with an ultrasonic pulse having acoustic properties selected so as to interact with the ultrasound sensitive particles and thus causing the release of the material. The ultrasound sensitive particles comprise sub-groups of ultrasound sensitive particles, the ultrasound sensitive particles within the same sub-group having their respective acoustic property causing each respective sub-group to interact independently with the sound wave.

  • Method and Apparatus for the Visualization of the Focus Generated Using Focused Ultrasound
    Publication number: 20080154132
    Abstract: The present invention relates to monitoring the focus of a therapeutic transducer in an interactive real-time manner by turning off the ultrasound transmits of the imaging transducer but continuing to receive in all directions with an imaging probe in order to identify the therapeutic beam focus. The therapeutic focused beam acts as the only transmit and as long as there is a scatterer at the focus, a strong receive signal will be generated to identify the focus.
