In an exemplary embodiment an ultrasonic head comprises at least one transducer element which, possibly via a liquid precursory path, transmits ultrasonic signals and receives echo signals. It is the object of the disclosure to design the applicator such that it is simply and rapidly adjustable to variable depth scanning. In accordance with the disclosure this object is achieved in that the liquid precursory path has the form of a sack, containing the liquid, which sack is capable of being coupled with the transducer element or elements on the ultrasonic head in the manner of a spacer by a readily detachable mounting arrangement.

Ultrasonic applicator

An ultrasonic-scan head is mounted by means of an articulated arm assembly; a swivel extension arm supports the assembly for rotation about a vertical central axis. Such vertical central axis is the isocenter for body sections to be scanned by the ultrasonic scan head. The construction of such an apparatus is desired which is particularly simple to handle during sectional plane selection. In particular, the apparatus mass to be moved is to be small so that a rotation of the entire scan system can also be conducted directly at the working location by the examining individual without requiring an assistant. This is achieved by virtue of the fact that the swivel extension arm, as the carrier for the articulated arm assembly, is coupled to a floor stand, and that the patient support can be arranged, preferably in a movably displaceable fashion, above the floor stand and above the extension arm which can be pivoted horizontally beneath said support so as to extend to either side of the support, or to an end of the support.
