Regularized spectral log difference technique for ultrasonic attenuation imaging
(Pontificia Universidad Católica del PerúPE, 2017-07-13)The attenuation coefficient slope (ACS) has the potential to be used for tissue characterization and as a diagnostic ultrasound tool, hence complementing B-mode images. The ACS can be valuable for estimation of other ... -
Robust Minimmun Variance Beamformer using Phase Aberration Correction Methods
(Pontificia Universidad Católica del PerúPE, 2017-04-28)The minimum variance (MV) beamformer is an adaptive beamforming method that has the potential to enhance the resolution and contrast of ultrasound images. Although the sensitivity of the MV beamformer to steering vector ... -
Separable dictionary learning for convolutional sparse coding via split updates
(Pontificia Universidad Católica del PerúPE, 2019-05-16)The increasing ubiquity of Convolutional Sparse Representation techniques for several image processing tasks (such as object recognition and classification, as well as image denoising) has recently sparked interest in ... -
Soft tissue characterization using different quantitative ultrasound modalities
(Pontificia Universidad Católica del PerúPE, 2019-10-24)Quantitative ultrasound has been used in several modalities for different experiments such as simulated phantom, physical phantoms, ex vivo and in vivo tissues. The potential of the ultrasound techniques could be useful ...
