Regularized spectral log difference technique for ultrasonic attenuation imaging
(Pontificia Universidad Católica del Perú, 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 Perú, 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 ...
A study of new methods and techniques for ultrasonic attenuation estimation
(Pontificia Universidad Católica del Perú, 2017-03-09)
The pathological states of biological tissue are often related in attenuation changes of itself. Thus,
information about attenuating properties of tissue is valuable for the physician and could be useful in
ultrasonic ...
