The Pros and Cons of Phase Coherence Imaging (PCI)
Phase Coherence Imaging, or PCI, is a technique proposed in 2009 to improve resolution and contrast in ultrasonic testing images. It is based on evaluating the coherence between the signals detected by all the elements of phased array ultrasonic testing probe. The intensity of a PCI image depends on the nature of the indications. Omnidirectional sources [...]
