Abstract

Some aspects of the extremely complex structure of the pulses utilized in medical ultrasound pulse-echo imaging devices are investigated. The following features are examined, in many instances from a fresh point of view: diffraction, Fourier representation, directivity spectrum, propagation of pulse projections, causality, superluminality, and header wave component. Analytical results are underpinned by experimental findings with (single-element) wideband ultrasound transducers. The discussion is conducted within the context of linear fields.
