In the ultrasound imaging process, the complex summation at the transducer face is assumed to be linear. The envelope detection process in B-scanning is a nonlinear step which yields essentially the magnitude of the complex field or voltage. It is shown that Rayleigh statistics govern the first-...
Speckle noise in ultrasound B-mode images of the longissimus dorsi or ribeye muscle acquired from live beef was statistically modeled and related to beef carcass intramuscular fat or marbling score that was determined visually on its corresponding carcass rib cross-section by experienced meat scientists...

ultrasound signals. This paper addresses the specific problem of defining and reducing the effects of speckle in ultrasound pulse-echo B-mode images. The reduction of speckle may be usefully regarded as a two stage procedure, consisting of (i) recognition - is the texture present in a clinical...
We optimized light transmission to the sample by applying ultrasound gel to the mouse skin and covering the gel with a 2 mm-thick one-sided antireflective- coated glass (650–1,050 nm), with the coating at the air–glass interface. For retinal and corneal imaging studies, mice were ...
Automatic Detection and Measurement of Structures in Fetal Head Ultrasound Volumes Using Sequential Estimation and Integrated Detection Network (IDN) Routine ultrasound exam in the second and third trimesters of pregnancy involves manually measuring fetal head and brain structures in 2-D scans. The proce...
