An ultrasonic array is a single transducer that contains a number of individually connected
elements. Recent years have seen a dramatic increase in the use of ultrasonic arrays for …

This paper describes a number of array post-processing methods developed for scanning
applications in non-destructive evaluation. The approach is to capture and process the full …

Ultrasonic arrays are increasingly widely used in nondestructive evaluation (NDE) due to
their greater flexibility and potentially superior performance compared to conventional …

相控阵超声后处理成像技术采用离线计算的方式对超声回波数据进行分析,
实现缺陷的成像及评价, 与基于实时成像的常规相控阵超声检测技术相比, 成像更清晰 …

It has a pivotal role in medical science and in industry to concentrate the acoustic energy
created with piezoelectric transducers (PTs) into a specific area. However, previous …

Ultrasonic phased array post-processing imaging techniques make testing and evaluation of
defects by using off-line algorithm. Greater defect imaging and characterization abilities …

Detection of weld defects for complex surface parts has always been a difficult point in
ultrasonic testing because the geometry complexity makes it difficult to arrange transducers …

High-resolution defect detection is an integral part of non-destructive testing (NDT).
Ultrasonic array transducers have been developed to respond to this need and provide high …

Accurate defect characterization is desirable in the ultrasonic nondestructive evaluation as it
can provide quantitative information about the defect type and geometry. For defect …

We propose a new scanhead design for combined ultrasound (US)/photoacoustic (PA)
imaging that can be applied to dual-modality microscopy and biomedical imaging. Both …
