  • Method of diagnosis and treatment of tumors using high intensity focused ultrasound
    Patent number: 9907982
    Abstract: A method of diagnosis and treatment of tumors using High Intensity Focused Ultrasound is provided. The method of diagnosing the presence of a tumor in a patient comprises the steps of subjecting a tumor to high intensity focused ultrasound (HIFU) to cause the tumor cells to release cellular material and evaluating the cellular material for a tumor marker. The method of treating a tumor in a patient can also comprise the step of subjecting a tumor to high intensity focused ultrasound (HIFU) to provoke an immune response.

  • Method and Apparatus for the Selective Treatment of Tissue
    Publication number: 20120150035
    Abstract: A HIFU System (100) is disclosed which may automatically generate a proposed treatment plan for treating a tissue treatment area (10) with HIFU Therapy. In one example, the proposed treatment plan includes a plurality of treatment sites selected based on a three-dimensional model generated from ultrasound data. In another example, the proposed treatment plan excludes portions of the tissue treatment area (10) corresponding to blood flow, such as the neuro-vascular bundles (20) when treating the prostate (11).
