Disclosed is a system and method for providing ultrasound strain imaging of a soft tissue, such as a prostate, so that the soft tissue may be more precisely targeted during radiation treatment. The system includes a mechanical arm with a pressure interface for applying incremental pressure to the patient's abdomen, and a data system for correlating the ultrasound signals acquired before and after each application of incremental pressure. By correlating the pre and post-pressure ultrasound signals, acoustic interfaces corresponding to the prostate, which define the contours of the prostate, may be displayed. Further, data corresponding to the contours of the prostate may be provided to a linear accelerator to enable the linear accelerator to more precisely target the prostate.
