    Abstract: The present technology is generally directed to filtering systems and methods for suppression of reverberation artifacts in ultrasound images. In some embodiments, a method of obtaining a filtered ultrasound image includes taking a first ultrasound image of a target tissue using an applicator. At least a portion of the applicator is moved such that the reverberation artifact ultrasound path length changes relative to the first position of the applicator. A second ultrasound image of the target tissue is then taken. The first and second ultrasound images are synthesized using at least one filtering method. The filtering method attenuates or removes reverberation artifacts in the synthesized ultrasound image.

    Abstract: Ultrasound data are collected from a thermal source and a mass of tissue before initiating therapy to measure two parameters of the bio-heat transfer equation (BHTE). The parameters are the thermal diffusivity (K) of the tissue and the magnitude of the thermal source (Q). Once the parameters have been obtained, the BHTE can be calibrated to the specific mass of tissue and the specific thermal source. The calibrated BHTE can be used to generate a temperature dependence curve calibrated to the thermal source and tissue, and spatio-temporal temperature maps, to facilitate pre-therapy planning. During therapy, ultrasound data are collected to determine if Q changes during therapy, and if so, the BHTE is recalibrated using the new Q value, increasing an accuracy of the temperature estimations.

    Abstract: High intensity ultrasound (HIU) is used to facilitate surgical procedures, such as a laparoscopic partial nephrectomy, with minimal bleeding. An apparatus is configured to emit HIU from one or more transducers that are attached to a minimally invasive surgical instrument. Such a tool preferably can provide sufficient clamping pressure to collapse blood vessels' walls, so that they will be sealed by the application of the HIU, and by the resulting thermal ablation and tissue cauterization. Such an instrument can provide feedback to the user that the lesion is completely transmural and that blood flow to the region distal of the line of thermal ablation has ceased. Similar instruments having opposed arms can be configured for use in conventional surgical applications as well. Instruments can be implemented with transducers on only one arm, and an ultrasound reflective material disposed on the other arm.
