Spatial compounding from ultrasonic RF data for speckle reduction in ultrasonic diagnostic imaging system

Description

This item was taken from the IEEE Conference ' Spatial compounding from ultrasonic RF data for speckle reduction in ultrasonic diagnostic imaging system ' Spatial compounding is an speckle reducing imaging technique in which a number of ultrasound images of a given target that have been obtained from multiple view points or angles are combined into a single compounded image by combining the data received from each data point in the compounded image. In this paper, we describe the spatial compounding using RF data which consists of demodulation, resampling, compounding and scan conversion. The demodulation process that extracts the echo signal from the 6.5MHz ultrasound echo signal is described. Resampling process that realigns the image plane considering the scan angle is explained. Compounding and scan conversion module are described.
