A remote palpation technique in breast imaging involves the use of multiple applications of radiation force in rapid succession throughout a two-dimensional plane in the target tissue medium (), and combination of the small, two-dimensional displacement maps from each force location into a single, larger remote palpation image (block). Apparatus for carrying out the foregoing method is also disclosed.

Method and apparatus for the identification and characterization of regions of altered stiffness

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.
