Pulsing Basis Functions for SDUV

Technology #2010-032

A method for producing tissue motion with customized frequency content is described in which push pulses are designed using orthogonal basis functions which then produce desired tissue motion. The push pulses can be a sequence of long duration, in which case motion detection A-lines can be interleaved among the pulses. The result is a more efficient method of making tissue move with optimal use of available power and energy delivery to the tissue, avoiding heating and inertial effects on the tissue.
