Acoustic Properties of Breast Fat [PDF]
ObjectivesThe American College of Radiology Breast Imaging Reporting and Data System (BI‐RADS) atlas for ultrasound (US) qualitatively describes the echogenicity and attenuation of a mass, where fat lobules serve as a standard for comparison. This study aimed to estimate acoustic properties of breast fat under clinical imaging conditions to determine ...

Mitigation of artifacts due to isolated acoustic heterogeneities in photoacoustic computed tomography using a variable data truncation-based reconstruction method [PDF]
Photoacoustic computed tomography (PACT) is an emerging computed imaging modality that exploits optical contrast and ultrasonic detection principles to form images of the absorbed optical energy density within tissue.

Application of adaptive filter in fruit quality inspection based on its acoustic properties
The fruit quality inspecting system consisted of a electromagnet, a striking ball wrapped in rubber, a sensor with 2 microphones at a distance of 0.06 m, a set of signal processing circuit, and a computer with a data acquisition board.

Characterization of sounds produced by three Brazilian Alpheus snapping shrimp species (Decapoda: Caridea) in laboratory [PDF]
Snapping shrimps produce snap sounds used for predation, defense, and reproduction. Despite their ecological importance, only a few studies have described the acoustic properties of these sounds.

Acoustic properties of dialysed kidney by scanning acoustic microscopy [PDF]
A correlation between acquired renal cysts in the dialysed kidney and renal cancer has long been debated, but no changes in the physical properties of kidneys at the microscopic level have been reported. The purpose of the present study was to classify the physical properties of the kidneys of patients undergoing haemodialysis at several stages of ...
