Medical diagnostic or similar ultrasonic scanning apparatus of basically A-scan form is adapted to give a B-scope display by the use of a mechanically flexible array of elongate members having its ends in mutually registered assemblies of which at least one is rectilinear. The other assembly is arranged for response thereacross to intensity modulated signal components representing reflection along the ultrasonic transducer beam path, and provides a corresponding light signal display at the one assembly for presentation to a camera. The flexibility of the array allows the light signal display to be manipulated in synchronism with the transducer by use of a simple mechanical linkage, so avoiding the complex electronics of convention B-scope equipment. The array can be of fiber optic form extending between a cathode ray tube A-scan output and a camera, or flexible electrical conductors leading to photodiodes or other light generating means.
