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 ...
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 ...
Backscatter coefficient estimation using highly focused ultrasound transducers
(Pontificia Universidad Católica del Perú, 2014-05-26)
The backscatter coefficient (BSC) is an intrinsic property that quantifies the amount of energy
that is reflected by a material as function of the ultrasound wave frequency. BSCs have been
proposed for decades for tissue ...
Soft tissue characterization using different quantitative ultrasound modalities
(Pontificia Universidad Católica del Perú, 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 ...
