    摘要: The present invention describes systems and methods for creating a virtual force field. A field source may be scanned over a region of interest on an object using a scanning technique such as vector scanning or raster scanning. The techniques disclosed herein describe applying the force field over volumetric (spatial) regions that can extend beyond the dimensions of the focal region of the force-field source (e.g., acoustic, electromagnetic, or optical source). The present invention may equally apply to multiple processes linked by cause and effect that exhibit unequal time dependence.

    摘要: Systems and methods for visualizing lesions in tissue are provided. The systems and the system and methods exploit the differential scattering of ultrasound waves by normal and lesioned tissues to image the lesions. Spectrum analysis of the harmonics in diagnostic ultrasound waves that are differentially backscattered from lesioned and normal tissues provides image contrast and resolution.

    摘要: An ultrasound transducer assembly includes a housing; a wedge-shaped acoustic modal convertor (AMC) in the housing with a first surface exposed by an opening in the housing, and a second surface that meets the first surface at a tip located in the housing, and extends from the tip at an angle into the housing, wherein the second surface has a recessed portion formed therein, wherein the second surface of the AMC is oriented at a specific oblique angle to the first surface of the AMC; and a piezoelectric ultrasound transducer disposed in the recessed portion of the second surface of the AMC, wherein the piezoelectric ultrasound transducer is connected to an electrically tuned circuit that resonates at a specific frequency and has a finite bandwidth.

    摘要: Diagnostic ultrasound is used to measure distance from a transducer to selected tissue structure. In one arrangement, the focal point of a high intensity focused ultrasound transducer is adjusted in accordance with measured distance to the selected tissue structure. In a second arrangement a transducer transport apparatus moves a transducer to maintain a selected distance from tissue structure.
