Ultrasound image artifact reduction

Abstract

There is provided a method for suppressing an image artifact in an ultrasound data set of an anatomical structure, the anatomical structure comprising a volume of biological tissue having a first acoustic attenuation and a fluid-filled cavity having a second acoustic attenuation lower than the first acoustic attenuation. The method comprises obtaining a first ultrasound data set of the anatomical structure including the biological tissue and a fluid-filled cavity, the first ultrasound data set comprising a region of interest; processing the first ultrasound data set using computer implemented signal or image processing techniques, wherein the processing includes compensating for the lower acoustic attenuation in the fluid-filled cavity; and obtaining a second ultrasound data set of the anatomical structure including the biological tissue and the fluid-filled cavity, wherein the second ultrasound data set comprises said region of interest and where image artifacts related to the lower acoustic attenuation of said fluid-filled cavity are suppressed relative to said first ultrasound data set.
