Phased array ultrasonics (PA) is an advanced method of ultrasonic testing that has applications in medical imaging and industrial nondestructive testing. Common applications are to noninvasively examine the heart or to find flaws in manufactured materials such as welds.
12 wrz 2024 · With the use of microelectromechanical system (MEMS) technology, we report an ultrasonic phased-array transducer, i.e., a 2D piezoelectric micromachined ultrasound transducer (pMUT)...
A phased array transducer is an ultrasonic testing transducer that contains a series of elements that can be pulsed in unison to direct sound waves in a specific direction. This makes it possible to test multiple inspection zones in a single instance.
Phased Array Ultrasonic Testing (PAUT), also known as phased array UT, is an advanced non-destructive inspection technique that uses a set of ultrasonic testing (UT) probes made up of numerous small elements.
Medical sonograms are commonly made with specialized multielement transducers known as phased arrays and their accompanying hardware and software. However, the applications of ultrasonic phased array technology are not limited to medical diagnosis.
5 cze 2024 · Compared to single-element ultrasonic transducers, phased array transducers have the advantages of adjustable focusing targets and higher focusing accuracy, making them more suitable for transcranial neuromodulation technology.
By using an ultrasonic phased array, the ultrasonic wave front can be focused on a certain point or steered in a specific direction; the inspection of a wide area can be achieved by electronically sweeping and/or refocusing without physically manipulating the transducers.
