Abstract
A new technique for computing images of transient ultrasound fields is presented. The theory of the method is based on the “directivity spectrum”, which is a generalisation of the angular spectrum. The method, in contrast to the angular spectrum approach, is particularly suited to the computation of transient fields, and it contains no evanescent waves. It allows computed pulse propagation over extended ranges
