The present invention relates to a method for producing an ultrasound image with a variable refractive lens () by transmitting a plurality of transmit beams (Tx-Tx) from an array of transducers () and receiving echo signals with the array of transducers () through the variable refractive lens () with an associated lens shape. By combining echo signals of receive lines from different transmit beams which are spatially related, the invention enable producing an image using image data. The invention is beneficial for high frequency ultrasonic imaging with the transducers being relatively larger sized than hitherto needed for high frequency applications. The array of transducers does not need to be “well-sampled”; i.e. having the width or size being comparably to the center wavelength of the ultrasonic signals to be received. This is particularly important at very high frequencies where well-sampled arrays would require very small elements that would be very challenging to manufacture.

The invention relates to an imaging apparatus () for imaging an interior of an object (). The imaging apparatus () comprises a first ultrasound sensor and a second ultrasound sensor for sensing the interior of the object at different frequencies, wherein the ultrasound sensing signals from the first ultrasound sensor are used for generating a first ultrasound image and a the ultrasound sensing signals from the second ultrasound sensor are used for generating a second ultrasound image. A larger frequency generally provides a smaller depth of penetrating the interior of the object and a larger spatial resolution than a smaller frequency. The imaging apparatus () can therefore provide the capability of simultaneously imaging the interior of the object with different spatial resolutions and at different penetration depths. This allows the imaging apparatus to improve the quality of imaging the interior of the object.

The weighted-average-based position () in the temporal domain is computed based on the sampling of shear wave displacement () along the propagation path. The weighting is, for example, by displacement observed at times () corresponding to sampling and represents the time of arrival of the shear wave at the shear-wave propagation path location being sampled. In some embodiments, the computed shear-wave times of arrival at respective locations are functionally related to known inter-location distances () to derive shear-wave group velocity. The derived velocity can serve as input into known algorithms for estimating shear elasticity of the medium, such as body tissue, for purposes of clinical diagnosis and therapy assessment.

An ultrasonic diagnostic imaging system produces an image of shear wave velocities by transmitting push pulses to generate shear waves. A plurality of tracking lines are transmitted and echoes received by a focusing beamformer adjacent to the location of the push pulses. The tracking lines are sampled in a time-interleaved manner. The echo data acquired along each tracking line is processed to determine the time of peak tissue displacement caused by the shear waves at points along the tracking line, and the times of peaks at adjacent tracking lines compared to compute a local shear wave velocity. The resultant map of shear wave velocity values is color-coded and displayed over an anatomical image of the region of interest.
