    摘要: Feedback of position is provided for high intensity focused ultrasound. The location of a beam from a HIFU transducer is determined using ultrasound imaging. The ultrasound imaging detects tissue displacement caused by a beam transmitted from the HIFU transducer. The displacement or information derived from the displacement may be used to determine a center line or point location (e.g., foci) of the tissues response to HIFU. The location of the line or point may be displayed in an image, such as an overlay or by color coding.

    摘要: Temperature related information or a temperature characteristic is detected, at least in part, with a medical diagnostic ultrasound system. Anatomy information from an ultrasound scan is used with modeling to determine the temperature or other temperature related parameter. Ultrasound information may be obtained in real-time with application of thermal therapy, so may be used to better control thermal treatment. The anatomy information may be used to align model features measured from a region. The anatomy information may be used as an input into the model. The anatomy information may be used to select an appropriate model, such as selection based on the type of tissue. The anatomy information may be used to correct an output of the model, such as accounting for temperature distribution due to an adjacent vessel.

    摘要: A shear wave velocity solution is provided for medical ultrasound imaging. Rather than determining shear wave information for each location based on distance from the origin of the shear wave and time to peak displacement for the location, displacement profiles resulting from different combinations of origin and detection locations are correlated. Shear information is detected using displacements from a diverse spatial combination of transmission locations and detection locations. The correlation combination is used in a same function for simultaneously solving for the delays for multiple lateral locations. Spatial diversity and layered correlation may provide for more accurate shear wave estimation.

    摘要: Magnetic resonance imaging frame rate is increased using ultrasound information. Magnetic resonance (MR) images may be provided at an increased frame rate relative to the MR acquisition. For times between acquisition of MR data, MR data may be created. To account for any change in position of tissue over time, ultrasound is used to track the location of tissue or other imaged structure. The ultrasound-based location information is used to indicate the position of intensities or values of the created MR data. MR images at a higher frame rate than the MR acquisition are generated, but with accuracy of relative position based on the ultrasound data.

    摘要: A viscoelastic property of tissue is measured in vivo. To collect more information and/or estimate viscosity, shear modulus, and/or other shear characteristics, an amplitude and phase modulated waveform is transmitted to the tissue. The displacement caused by the waveform over time includes displacements associated with response to different frequencies. By examining the displacement in the frequency domain, one or more viscoelastic properties may be calculated for different frequencies. The frequency response may indicate the health of the tissue.
