The present invention relates to an ultrasound probe head (1), especially for HIFU treatment, comprising a treatment ultrasound transducer (2) and an imaging ultrasound transducer (3). The imaging transducer (3) comprises a shield element (4) configured such that most of the energy of ultrasound waves (10) reflected in the direction of the imaging transducer (3) are held back by said shield element (4). The shield element (4) is configured in such a way as not to interfere with the emission of the imaging ultrasound waves (7).
