Signal-domain speed-of-sound correction for ring-array-based photoacoustic tomography [PDF]
PhotoacousticsPhotoacoustic imaging combines the advantages of optical and acoustic imaging, making it a promising tool in biomedical imaging. Photoacoustic tomography (PAT) reconstructs images by solving the inverse problem from detected photoacoustic waves to ...

Reconstructing multiple initial pressure and speed of sound distributions simultaneously in photoacoustic tomography [PDF]
PhotoacousticsImage reconstruction in photoacoustic tomography relies on an accurate knowledge of the speed of sound in the target. However, the speed of sound distribution is not generally known, which may result in artefacts in the reconstructed distribution of ...

Speed of sound index for liver steatosis estimation: a reliability study in normal subjects [PDF]
Diagnostic and Interventional Radiology, 2022 PURPOSENon-alcoholic fatty liver disease (NAFLD) is the most widespread type of chronic liver disease in the Western countries. Ultrasound (US) is widely used for NAFLD staging.

Evaluation of glycerol speed of sound
Research and Review Journal of Nondestructive Testing, 2023 The speed of sound in the liquid glycerol was calculated from the wave propagation time measurement in through transmission mode by using a designed acoustical cell. Measurements were carried out at atmospheric pressure and temperatures ranging from 298.

HOLOGRAPHY AND THE SPEED OF SOUND [PDF]
International Journal of Modern Physics A, 2010 We study the approach of the speed of sound towards the value [Formula: see text] at high temperatures in a general class of strongly interacting theories. This class includes theories holographically dual to a theory of gravity coupled to a single scalar field, representing the operator of the scale anomaly.

Beyond the speed of SOUND [PDF]
Breast Cancer, 2020 Much anticipation awaits the results of the SOUND trial, (Gentilini and Veronesi in Breast 21:678-681, 2012) which may prove the futility of performing sentinel node biopsy (SNB) in low-risk breast cancer patients. However, do we really not know the answer to the questions that the SOUND trial poses already? Consideration must be taken of the very much
