摘要:
A system and method are disclosed that facilitate generating visual representations of characterized tissue based upon ultrasound echo information obtained from a portion of an imaged body. The system includes a first filter having a first filter band that is applied to a near range portion of the ultrasound echo information to render near range filtered echo information. A second filter, having a second filter band that covers a frequency range of the first filter band, is applied to a far range portion of the ultrasound echo information to render far range filtered echo information. The system furthermore includes a set of characterization criteria that are applied to the near and far range filtered echo information. The characterized near and far range image data are thereafter combined into a single tissue-characterization image.
