Acoustic and video imaging system for quality determination of pharmaceutical products"

with the aim of identifying failure mechanism in oriented strand boards, failure behavior of wood strands under tensile load was investigated using acoustic emission technique. resinated and unresinated strands were arranged at top, middle and bottom section of the board before pressing. tensile and acoustic emission tests were performed simultaneously on treated and control samples. using tens...

Articulatory patterns of the lateral approximant /1/, both dark and light allophones, in American English were analyzed through magnetic resonance imaging (MRI) and electropalatography (EPG). Vocal tract lengths, area functions, and cavity volumes, were measured from the MR images, while EPG data were used for studying interand intra-speaker variabilities in lingua-palatal contact patterns. Aco...

Mechanical index (MI) is a measure of acoustic power. It is generally omitted during routine echocardiographic imaging. By adjusting the MI, an echocardiographer can perform various contrast-specific imaging modalities during the same session.

Ultrasound (US) and photoacoustic (PA) multimodality imaging has the advantage of combining good acoustic resolution with high optical contrast. The use of an all-optical scanhead for both imaging modalities can simplify integration of the two systems and miniaturize the imaging scanhead. Herein we propose and demonstrate an all-optical US/PA scanhead using a thin plate for optoacoustic generat...
