  • Method and system for guided shielding of a patient volume from ultrasound energy
    Patent number: 9375588
    Abstract: In order to decrease collateral heating of ribs and tissue surrounding the ribs in a patient during high-intensity focused ultrasound (HIFU) therapy, shielding material may be positioned on or adjacent to an external surface of the patient and aligned with ribs to be protected using a magnetic resonance imaging (MRI) system. The MRI system may be used to image the shielding material and the ribs to be protected, and an error of alignment between the ribs to be protected and the shielding material may be determined based on the images. The shielding or masking material may be repositioned based on the determined error of alignment, images of the shielding material and the ribs to be protected may be reacquired, and the error of alignment may be redetermined based on the reacquired images until the shielding material is aligned with the ribs to be protected.
