Pulse compression technique applied to ultrasonic nondestructive testing of concrete
The pulse compression technique is successfully and widely used in many fields for improving the signal to noise ratio (SNR); which is especially useful when the environment is noisy and the SNR is poor. Since high frequency ultrasound is strongly attenuated in concrete, only low frequency ultrasound can be used in ultrasonic nondestructive testing (NDT) of concrete. In this study the pulse com...
متن کاملAngle Beam Ultrasonic Testing Models and Their Application to Identification and Sizing of Cracks
Identi fication and sizing of surface breaking cracks using angle beam ultrasonic testing in practical situations quite often becomes a very diffi cult task due to the presence of non-relevant signals caused by geometric refl ectors. The present work introduces effective and systematic approaches to take care of such a diffi culty by use of angle beam ultrasonic testing models that can predict ...
متن کاملMicroparticle trapping in an ultrasonic Bessel beam.
This paper describes an acoustic trap consisting of a multi-foci Fresnel lens on 127 μm thick lead zirconate titanate sheet. The multi-foci Fresnel lens was designed to have similar working mechanism to an Axicon lens and generates an acoustic Bessel beam, and has negative axial radiation force capable of trapping one or more microparticle(s). The fabricated acoustic tweezers trapped lipid part...

متن کاملUltrasound-Guided Needle Technique Accuracy
BACKGROUND AND OBJECTIVES Ultrasound-guided regional anesthesia facilitates an approach to sensitive targets such as nerve clusters without contact or inadvertent puncture. We compared accuracy of needle placement with a novel passive magnetic ultrasound needle guidance technology (NGT) versus conventional ultrasound (CU) with echogenic needles. METHODS Sixteen anesthesiologists and 19 reside...
