An ultrasound treatment head (1) for an apparatus for treating a patient with ultrasound comprises at least one active element (2) for converting an electric signal into ultrasound and a vacuum cup (13) having an upper part (14) and a lower part (15). The active element (2) is mounted in the upper part (14) and the vacuum cup (13) provides a vacuum chamber (18) with a holding space for a gel pad (19). The upper part is adapted to act as a spring suspension for the active element to lower the active element into the lower part. The active element (2) is provided with a positioning ring (20) protruding with respect to the active element. This positioning ring (20) determines the location of the gel pad (19) within the holding space.
