Abstract

A replaceable attachment for an ultrasound probe includes a ring-like fastening region for fastening the attachment to the ultrasound probe, and a flexible membrane arranged on the fastening region. A first liquid or gel-like contact medium is applied to an inner contact surface of the membrane. The contact surface makes contact with an end face of the ultrasound probe when an attachment is fastened to the ultrasound probe. Before the attachment is fastened, the first contact medium is distributed on the contact surface in such a manner that, in an array region of the contact surface, a quantity of the first contact medium per surface is at least twice as large as in a remaining region of the contact surface. A positioning and extent of the array region is adapted to a positioning and extent of a piezo array of the ultrasound probe.
