Abstract :
A set of strip masks have been developed for high frame rate imaging with steered plane wave (SPW), steered diverging beam (SDB), and limited-diffraction beam (LDB) transmissions. These masks enhance image contrasts significantly. In addition, an image mask was developed for reconstructed images. The mask allows the reconstructed images to have a similar brightness within their fields of views.
