The amplified beamformed responses of the hyperechoic region and its trailing artefacts in the phantom experiment using: a the normal PWC, b the SVD filter method and c our proposed method. All images are shown with a dynamic range of 60 dB. The orange arrow points to the sidelobe artefacts brought by the circular hypoechoic region
