Abstract
A transducer array includes at least one annular shear wave generation transducer that defines an interior area, the at least one annular shear wave generation transducer being configured to generate a shear wave excitation to a region of interest such that the shear wave excitation excites at least a part of a corresponding cylindrical portion of the region of interest and shear waves propagating from the cylindrical portion of the region of interest constructively interfere in an interior region of the cylindrical portion of the region of interest; and at least one tracking transducer positioned in the interior area of the at least one annular shear wave generation transducer, the at least one tracking transducer being configured to detect a shear wave in the interior region of the region of interest.
