Abstract
Ultrasound energy is transmitted into tissue in a first direction to provide a virtual extended shear wave source. The virtual extended shear wave source generates an extended shear wave that propagates in a second direction substantially orthogonal to the first direction to cause movement in the first direction of tissue that is offset from the virtual extended shear wave source in the second direction. Related ultrasound imaging systems and computer program products are also disclosed.
