    Abstract: An apparatus for delivering acoustic energy to a target site adjacent a body passage includes first and second elongate members, each carrying one or more transducer elements on their distal ends. The first and/or second elongate members include connectors for securing the first and second elongate members together such that the transducer elements together define a transducer array. The first and second elongate members are introduced sequentially into a body passage until the transducer elements are disposed adjacent a target site. Acoustic energy is delivered from the transducer elements to the target site to treat tissue therein. In another embodiment, the apparatus includes a tubular member and an expandable structure carrying a plurality of transducer elements. The structure is expanded between a contracted configuration during delivery and an enlarged configuration when deployed for delivering acoustic energy to a target site adjacent the body passage.

    Abstract: A method of imaging a site of interest in a body using an ultrasound probe comprising a plurality of ultrasound transducer elements comprises obtaining an ultrasound image of a pass zone between the ultrasound probe and the site of interest. The image includes the site of interest and a plurality of tissue regions in a pass zone between the site of interest and the ultrasound probe. Boundaries of a selected tissue region in the pass zone are determined from the image. Focusing delay times are then computed for each ultrasound transducer element based in part on the speed of sound in the selected tissue region other than an average speed of sound in body tissue, and the boundaries of the selected tissue region. Preferably, a speed about the speed of sound in the selected tissue region is used and more preferably the speed of sound in the selected tissue region is used. Refraction may be considered, as well. Ultrasound imaging of the site of interest is then conducted employing the computed delay times. Fat and bone tissue regions are typically selected if present. Other tissue regions may be selected, as well. The boundaries of the tissue region or regions may be determined by segmentation. Tissue inhomogeneity is thereby compensated for, improving image contrast resolution. Ultrasound imaging systems and software are also disclosed. A new ultrasound probe comprising high and low frequency transducer elements is also disclosed.
