Acoustic Radiation Force Impulse (ARFI) images are used to visualize spatial variations in soft tissue elasticity by showing the displacement of each pixel in response to an applied radiation force. However, accommodations for spatial variations in the applied radiation force itself have been limited. When imaging a phantom, reference lines that contain no targets can be used to calibrate the depth-dependence of the applied force, but this is not feasible in vivo. We present here a method of estimating the spatially-varying applied force map via automatic segmentation of the matched B-Mode image, and use these maps to normalize ARFI image to have decreased spatial variability.
