This invention relates to diagnostic and screening medical ultrasound in general and to ultrasound-stimulated detection and location, Image-based Dynamic Ultrasound Spectrography, Acoustic Radiation Force Imaging, and similar modalities in particular. In this invention, an ultrasound signal is emitted into tissue and the resulting radiation force induces localized lower frequency oscillations, which are then received by various acoustic sensors and analyzed to determine certain features or characteristics of the interrogated region. The sensors can be arranged in the form of a ring, in any random arrangements, or positioned in specifically chosen locations. An ultrasonic imaging and excitation transducer generates certain stimulating signals which are received by the breast tissues and which, if they contact a microcalcification, other target, or any region with sharply different mechanical and visco-elastic properties, will result in reflected, demodulated, or re-radiated signals. These signals will propagate away from the targets and detected by the various receiving sensors.
