Full correction for spatially distributed speed-of-sound in echo ultrasound based on measuring aberration delays via transmit beam steering.
Aberrations of the acoustic wave front, caused by spatial variations of the speed-of-sound, are a main limiting factor to the diagnostic power of medical ultrasound imaging. If not accounted for, aberrations result in low resolution and increased side lobe level, over all reducing contrast in deep tissue imaging. Various techniques have been proposed for quantifying aberrations by analysing the...

15 صفحه اولReference data for bone speed of sound measurement by quantitative ultrasound in healthy children
Introduction The aim of the study was to establish reference data for tibia and radius bone ultrasonic speed of sound (SOS) measurement in our pediatric population, and to compare the results with original (built-in) reference data. We also investigated the relationship between SOS Z-scores and anthropometric parameters and bone markers. Method SOS was measured in 463 healthy children (1– 16 ye...
متن کاملUltrasound measurement of atherosclerosis.
Ultrasound Measurement of Atherosclerosis To the Editor: The recent review of intima-media thickness (IMT) measurements by Bots et al,1 while presenting cogent arguments for use of maximum versus mean carotid IMT for studies of interventions, failed to discuss important limitations of IMT. They claim as an important advantage of IMT, as opposed to morbidity and mortality as end-points, the cons...
متن کاملDeformation Correction in Ultrasound Imaging
Tissue deformation in ultrasound imaging is an inevitable phenomenon and poses challenges to the development of many techniques related to ultrasound image registration, including multimodal image fusion, freehand three-dimensional ultrasound, and quantitative measurement of tissue geometry. In this thesis, a novel trajectory-based method to correct tissue deformation in ultrasound B-mode imagi...
