1. A method of characterizing tissue, comprising: collecting ultrasound echo information from a portion of an imaged body; applying a first filter, having a first filter band, to a near range portion of the ultrasound echo information to render near range filtered echo information; applying a first characterization criterion to the near range filtered echo information to render a near range tissue characterization image; applying a second filter, having a second filter band that completely covers and is broader than a frequency range of the first filter band, to a far range portion of the ultrasound echo information to render far range filtered echo information; and applying the first characterization criterion to the far range filtered echo information to render a far range tissue characterization image.
