Ultrasound image processing

摘要

Method, system, and computer program product are provided for processing an ultrasound image, in particular an image of inhomogeneous tissue. The method includes: segmenting tissue in a received ultrasound image; creating a mask of pixels centred on a pixel in a tissue area, wherein the pixels in the mask are within a given decibel range of the central pixel and within a segmentation boundary; and assigning an attenuation to the central pixel by estimating the attenuation of the pixels in the mask. The received ultrasound image may be a raw image the method may include creating an image of an attenuation mapping of attenuations for each pixel in a tissue area. Alternatively, the received ultrasound image may be a time gain compensated image the method may include determining areas of relatively high or low attenuation.

1. A computer-implemented method for processing an ultrasound image performed by a computerized device, the method comprising:
segmenting tissue in a received ultrasound image, the ultrasound image comprising a plurality of pixels representing a tissue area; creating a mask of pixels around a central pixel in the tissue area, wherein the pixels in the mask are within a given decibel range of the central pixel and within a segmentation boundary; and assigning an attenuation to the central pixel by estimating the attenuation of the pixels in the mask, assuming that attenuation of the pixels in the mask is either uniform along the mask or constant across sequential segments along the mask.
