摘要： The shear modulus information is measured for sparse locations in a scanning field of view. For other locations, the shear modulus information is calculated as a function of the sparsely measured values and strain information. For example, shear modulus values are provided for every grid point in a field of view based on strain values for every grid point and on sparsely measured shear modulus values.

摘要： Complex response of tissue is calculated as function of a convolution relationship associated with measured strain with applied stress. In the Fourier or frequency domain, the convolution is a simple algebraic computation, such as multiplication. The complex response provides elasticity and viscosity information, assisting diagnosis. Complex compliance may be directly calculated from the strain and stress. Complex fluidity may be directly calculated from strain rate and stress.

摘要： Using compression, tissue elasticity data from two or more different fields of view is acquired. Since different amounts of compression may be used for the different fields of view, the dynamic range of the elasticity data is updated. A panoramic elasticity image is generated from the updated elasticity data of multiple fields of view. A panoramic elasticity image represents the combined fields of view for the elasticity data.

摘要： Measurements in diagnostic medical imaging are cross-referenced. A measurement made for one type of data is reflected in an image for another type of data. For example, a length is measured from ultrasound data. A line associated with the length is displayed on the ultrasound image. In a magnetic resonance image (MRI), the same line is displayed at a corresponding location. The same measurement may also be made with the MRI data and reflected in the ultrasound image. Each image shows both measurements in this example. The difference in the same measurements from different types of data may be useful for diagnosis. In the above example, the length is measured from ultrasound and from MRI. The difference between the two measured lengths may provide diagnostically useful information.

摘要： Shear wave characteristics are estimated from analytic data. Measures of displacement are converted into complex representations. The magnitude and/or phase components of the complex representation may be used for estimating various characteristics, such as velocity, center frequency, attenuation, shear modulus, or shear viscosity. The zero-phase of the phase component represents an occurrence of the shear wave at that location.

摘要： Information associated with shear calculation is also displayed in ultrasound shear wave imaging. More information than just a shear wave image is provided for diagnosis. Information about the quality or variables used to determine shear is also displayed. This additional information may assist the user in determining whether the shear information indicates tissue characteristics or unreliable shear calculation.

摘要： Adaptive image optimization is provided in induced wave ultrasound imaging. The values for various transmit and receive parameters may be set adaptively. Based on feedback from use with a given patient, the values are set to better optimize signal-to-noise ratio, off-time, tracking accuracy or other consideration. Transmit frequency, F-number, line spacing, tracking pulse repetition frequency, line sampling count, and/or push pulse amplitude values may adapt.

摘要： Shear waves are detected with ultrasound. The detection of the shear wave is constrained using prior measurements in a more controlled environment (e.g., less noise). For example, shear waves measured in a phantom are used to constrain the detection of shear waves in a patient to avoid false positive detections.

摘要： High intensity focused ultrasound (HIFU) is registered with imaging. The effects of transmission from a HIFU transducer, such as a rise in temperature, are detected by a separate imaging system. By using multiple transmissions, a plurality of locations of the transmissions from the HIFU transducer are determined within the imaging system coordinates. A transform relating the imaging system coordinates to the HIFU transducer coordinates is determined from the detected effects. The transform may be used to relate locations indicated in images of the imaging system with coordinates of the HIFU transducer for application of HIFU. The imaging system may not have to scan the HIFU transducer or fiducials and a fixed relationship may not be needed.
