/4/, are extended in this paper in order to investigate speckle in ultrasound computerized reflection mode tomography (UCTR). UCTR can be explained as a numerical superposition of several B-Scans of a cross-sectional plane obtained from different aspect angles. The superposition consists of a ...
Speckle in Ultrasound B-Mode Scans -Ultrasound images obtained with a simple linear or sector scan show a granular appearance, called "speckle." This speckle is analyzed. The reduction in sp... CB Burckhardt,MEMBER,IEEE - 《IEEE Trans Sonics & Ultrasonics》 被引量: 1369发表: 1978年 Coherent...

The coherent nature of the ultrasound imaging pulse allows for the possibility of interference effects and the appearance of the speckle artefact which occurs in virtually all medical ultrasound signals. Speckle is often regarded as noise, and as such ha

We continue by confirming the expected functional dependence of the speckle contrast on the number of averaged scans. Finally, we provide demonstrations of SM-OCT for imaging the tissues of living subjects: a mouse retina and cornea, a mouse ear pinna and human fingertip skin. In all examples,...

ULTRASOUNDTRANSVAGINAL COLOR DOPPLERThe linear Biot theory for wave propagation in porous media is applied to waves in an open cell permeable foam. The relevant physical parameters are specified. In general two wave modes exist, with their own frequency dependent wave speeds and damping factors. The...
