ABSTRACT Ultrasonic scanning apparatus is disclosed. The apparatus includes electronic delay circuitry for delaying echo signals produced in use by a multi- plicity of transducers of the apparatus such that the phase relationship between respective echo signals is substantially maintained. The circuitry comprises a multiplicity of partial-line stores; each partial-line store being adapted for storing data corresponding to a part of an ultrasonic scanning line, asso- ciated in groups of at least three with respective ones of the transducers and control means arranged such that, in use, data corresponding to echo signals is sequentially written in to the partial-line stores of the group for each of the transducers, beginning with the first such transducer to receive an echo signal, until at least the first partial-line store of the group for the last such transducer to receive an echo signal has been supplied with data, after which, data can be simultaneously read out from all of the partial-line stores.
