Ultrasonic Imaging and Quantitative Nondestructive Evaluation of the Hearts of Patients

Cross fertilization between the quantitative nondestructive evaluation (QNDE) community and the diagnostic medicine community in the area of ultrasonics represents an attractive but challengin~ goal. High resolution, real-time ultrasonic imaging is routinely available not only in major medical centers but even in modest community hospitals. However, quantitative ultrasonic evaluation based on t...

Ultrasonic Evaluation of Local Human Skin Anisotropy

Abstract Anisotropy level of human skin is typically obtained by multi-axial tensile test, cutometry, elastography, ultrasonic imaging, etc. Most of the methods are time-consuming, expensive, or not suitable for in-vivo measurements. In this paper a new easily-applicable method for immediate evaluation of human skin local anisotropy is described. Results in this area are of great interest in de...

Simulation of Ultrasonic and Electromagnetic Nondestructive Evaluation of Corrosion

The influence of corrosion on ultrasonic and electromagnetic nondestructive evaluation results has been simulated for 2-layer aluminum aircraft fuselage. Simulations have been performed with respect to ultrasonic time-of-flight measurements aiming on the detection of corrosion at the backwall of the first aluminum layer. Calculations of the eddy current probe response have been performed, where...

Nondestructive ultrasonic evaluation of formability of metallic sheets

An indication of the formability of metallic sheet is determined using a correlation between nondestructively measurable ultrasonic properties and a formability index. A calibration relation is initially established by measuring ultrasonic velocities at various angles to the rolling direction of sheet specimens with noncontacting electromagnetic acoustic transducers, calculating an ultrasonic c...
