Abstract
A device and method used to log images of target objects with ultrasound transducers. The object may be a fluid-carrying tubular, such as a pipeline. The transducers operate as phased arrays, insonifying areas of the target object with a plane wave and then storing the reflected signals. The signals are sampled and summed for each pixel, by considering various paths taken by the wave from transmitting to receiving via that pixel. Refraction and reflection from surfaces are used to determine segments of the paths.
