  • Patent number: 11364011
    Abstract: An apparatus can be used to generate acoustic imaging pulse sequences and receive corresponding echoes elicited by the acoustic imaging pulse sequences. An acoustic radiation force (ARF) pulse sequence can be generated to agitate a contrast medium in a tissue region between the acoustic imaging pulse sequences. A decorrelation between images corresponding to the received echoes can be determined. A weighting map can be applied to an image to weight a region of the image corresponding to a spatial location of the contrast medium using the determined decorrelation. In an example, the receiving of corresponding echoes elicited by the acoustic imaging pulse sequences can include receiving acoustic energy having a range of frequencies offset from a fundamental frequency associated with the acoustic imaging pulse sequences. An acoustic imaging pulse sequence can include a pulse having an inverted amplitude envelope with respect to another pulse included in the sequence.

  • Patent number: 11324413
    Abstract: A method to increase the reliability and clinical utility of diffusion tensor imaging (DTI) of traumatic brain injury (TBI) in single subjects and a semi-automated method of identifying and quantifying small hemorrhages using susceptibility-weighted images (SWI) of single subjects include storing an image template formed from control subjects, storing a brain image of the single subject, correcting for image acquisition differences of the control subjects and single subject, and performing regional analysis of the brain image of the single subject. The method may include analysis of fractional anisotropy values that are age-corrected between the control subjects and the single subject before performing voxel-based analysis (VBA), and a hybrid VBA and tract-based spatial statistical (TBSS) analysis with the VBA and TBSS results combined using a statistical calculation. The resulting combined DTI image may be further combined with an SWI image, FLAIR image, and/or T1 image of the single subject.

  • Patent number: 11207547
    Abstract: A method and system for providing ultrasound treatment to a tissue that contains a lower part of dermis and proximal protrusions of fat lobuli into the dermis. An embodiment delivers ultrasound energy to the region creating a thermal injury and coagulating the proximal protrusions of fat lobuli, thereby eliminating the fat protrusions into the dermis. An embodiment can also include ultrasound imaging configurations using the same or a separate probe before, after or during the treatment. In addition various therapeutic levels of ultrasound can be used to increase the speed at which fat metabolizes. Additionally the mechanical action of ultrasound physically breaks fat cell clusters and stretches the fibrous bonds. Mechanical action will also enhance lymphatic drainage, stimulating the evacuation of fat decay products.
