Component frame enhancement for spatial compounding in ultrasound imaging

摘要

Steered spatial compounding is provided in ultrasound imaging. Component frames of data associated with different spatial response are processed to identify different sources of signals. Matched filtering and/or spatial variance with erosion distinguish between sources of signals, such as distinguishing between (1) anatomical structure and (2) soft tissue and/or noise. The locations in the patient are segmented by the source of signals and different compounding is applied for the different sources.

主权项

1. A method for spatial compounding in ultrasound imaging, the method comprising:
acquiring steered component frames of data, each of the steered component frames of data representing a same overlap region of a patient and being responsive to different imaging angles; filtering, with matched filters, each of the steered component frames of data along different directions, the filtering providing multiple filtered component frames of data for each steered component frame of data; combining the multiple filtered component frames of data for each of the steered component frames, the combining providing a combined component frame of data for each of the steered component frames of data; segmenting the combined component frames; compounding the combined component frames of data together as a function of the segmenting; and generating an image of the overlap region from a result of the compounding.
