Zernike ultrasonic tomography for fluid velocity imaging based on pipeline intrusive time-of-flight measurements

In this paper, we propose a novel ultrasonic tomography method for pipeline flow field imaging, based on the Zernike polynomial series. Having intrusive multipath time-offlight ultrasonic measurements (difference in flight time and speed of ultrasound) at the input, we provide at the output tomogram...
