Improved developments in digital ultrasound technology and the use of high-frequency broadband transducers make ultrasound (US) imaging the first screening tool in investigating superficial tissue lesions. US is a safe (no ionizing radiation), portable, easily repeatable, and cheap form of imaging compared to other imaging modalities. US is an excellent imaging modality to determine the nature of a mass lesion (cystic or solid) and its anatomic relation to adjoining structures. Masses can be characterized in terms of their size, number, component, and vascularity with US and Doppler US especially with power Doppler US. US, however, is operator dependent and has a number of artifacts that can result in misinterpretation. In this review, we emphasize the role of ultrasound, particularly power Doppler, in superficial soft-tissue lesions.

Ultrasonic testing (UT) is widely used for the nondestructive testing (NDT) of composite materials in the aerospace industry. Liquid-coupled piezoelectric ultrasonic transducers are the most common technology used in this field; however, liquid coupling agents are not always practical, economical, or compatible with materials that cannot get wet. Alternative couplant-free technologies such as air-coupled ultrasound or laser ultrasound (LUS) are available, but either lack the required sensitivity and resolution, or are very costly, large, and sensitive to surface condition and properties. In this paper, we introduce a new couplant-free approach using laser excitation and a commercially available optical micro-phone. This technique is termed laser-excited acoustics (LEA) NDT, which combines the advantages of a contact-free ultrasound technology with the potential for improved sensitivity and resolution required for NDT in industrial environments. We will demonstrate the capabilities of LEA on aerospace composite parts made of carbon and glass fiber–reinforced polymer (CFRP/GFRP) under realistic conditions.

Abstract Live animal ultrasound measurements were taken on thirty-two feedlot steers and heifers for estimation of carcass endpoints including 12th rib fat thickness (FTU), ribeye area (REAU) and intramuscular fat (%FatU). Ultrasound measurements were collected by an inexperienced technician using an Aloka 500 ultrasound unit using Beef Image Analysis (BIA) software. The objective of the study was to evaluate carcass differences of four sire breed types including Angus (n = 11), Ultrablack (n = 6), Nelore (n = 6), Braunvieh (n = 1) and Angus X Nelore X Braunvieh hybrid (n = 8). Carcass data collected at harvest included 12th rib fat Thickness (FTC), Ribeye area (REAC), marbling score (MS), Yield Grade (YG), and Quality Grade (QG). The data were analyzed using SAS to determine breed effects. Means for FTU, FTC, REAU, REAC, %FatU and MS were 0.59 cm, 0.57 cm, 90.80 cm2, 83.53 cm2, 4.83%, and 483.75, respectively. There was no significant difference (P > 0.05) in YG and FT due to breed of sire. However, there was a trend for sire breed for ribeye area (P = 0.0728) for Angus X Nelore X Braunvieh cross and MS (P = 0.0786) for Ultrablack. Pearson correlation values between FTU and FTC, REAU and REAC, and %FatU and MS were 0.1217 (P = 0.05068), 0.3545 (P = .0465) and 0.5161 (P = 0.0025), respectively. These data suggest little differences existed in carcass attributes between various sire breeds out of a set of crossbred commercial cows.
