1. An ultrasound processing system for elastography, comprising:
- an ultrasound interface that receives ultrasound imaging information; and
processing electronics coupled to the ultrasound interface and configured to utilize the ultrasound imaging information to use time-varying frame selection to estimate displacement and/or strain;
wherein the processing electronics perform the time-varying frame selection by comparing a single frame to a plurality of previous frames and selecting a single comparison set for each frame for displacement and/or strain estimation.

Abstract
An ultrasound processing system includes an ultrasound interface and processing electronics. The ultrasound interface receives imaging information. The processing electronics are coupled to the ultrasound interface and are configured to utilize the ultrasound imaging information to use time-varying frame selection to estimate strain so that the processing electronics perform the time-varying frame selection by comparing a single frame to a plurality of previous frames and selecting a single comparison set for each frame for strain estimation.
