  • Publication number: 20150173715
    Abstract: A local user obtains data on the response of internal tissues of a subject to a non-invasive imaging system, choosing sensor positions according to a geometric display. The data obtained are evaluated with respect to predefined quantitative values. The process of obtaining and processing the internal tissue response data is repeated until an image meeting predetermined image quality characteristics is obtained. Specific or general content of the image may be restricted by the local processor, with a distal processor receiving the obtained image data, so as to limit specific or general types of image information from being viewed by the local user, such as image data that can be used to identify the sex of a fetus within the subject.

  • Publication number: 20140243783
    Abstract: Interstitial tissue structure is treated with a flowable liquid agent by: providing a delivery cannula having a proximal end and a distal end and an external surface with at least one expandable member located on the external surface of at least one catheter or needle. The delivery cannula is inserted into live tissue, creating a hole in the tissue surrounding the delivery cannula. Contact is made against an inner surface of the hole with contact pressure from the at least one expandable member, said contact pressure establishing a first level of stress in tissue surrounding the hole in the tissue. The expandable member is expanded to increase the contact pressure and provide a second level of stress in the tissue surrounding the hole in the tissue to a second level of stress that is greater than the first level of stress.

  • Patent number: 8582397
    Abstract: Known time reversal methods consist of three steps which may be listed as (i) the recording of signals and (ii) the time reversing of the recorded signals, and (iii) the transmission of the time-reversed signals. The first and third steps of the above process are retained, but the second step is modified. The empirical signal is transformed to fit mathematical forms taught by the mathematics of singularity and catastrophe theory that ensure a structural stability to the waveforms that will be received, when the time reversed signals are transmitted again. This structural stability ensures robustness of the waveform and the predominant direction of the flux of energy of the waveform, and improves controllability of the location of the high magnitude regions of the energy flux despite limited knowledge of the exact properties of the medium. Applications to drug delivery in the brain, and geophysical applications are envisaged.

  • Patent number: 8545405
    Abstract: Acoustic waves exhibit force that pushes objects along the direction of sound propagation. Precise motions require well-focused beams. The technique of time-reversal acoustics (TRA) overcomes beam distortions introduced by propagation along irregular paths to focus sound without knowledge of the medium properties. TRA requires a small receiver to be placed at a point of desired focus. The invention disclosed refines TRA by introducing data matching schemes to extend the points of focus beyond the location points of the receivers. With as few as two receivers, a large region can be manipulated with well-focused acoustic beams and with no receiver at a desired point of focus. Applications are described in drug delivery in medicine; environmental fluid contaminant control; and in oil exploration, for retrieving oil stuck in underground pockets.
