Beschreibung
Zusammenfassung:	A scanning apparatus for imaging an object, comprising an ultrasound transducer comprising a transmitter configured to transmit ultrasound signals in a first direction towards an object and a receiver configured to receive reflected ultrasound signals from an object; and a backing block for absorbing ultrasound signals, located adjacent the transducer along a second direction opposite to the first direction; the backing block comprising an inner surface facing the transducer, the inner surface comprising a non-planar feature configured to increase the absorption of ultrasound signals by the backing block. L'invention concerne un appareil de balayage pour imager un objet, comprenant un transducteur ultrasonore comprenant un émetteur conçu pour émettre des signaux ultrasonores dans une première direction vers un objet et un récepteur conçu pour recevoir des signaux ultrasonores réfléchis provenant d'un objet ; et un bloc de support pour absorber des signaux ultrasonores, situé à proximité du transducteur le long d'une seconde direction opposée à la première direction ; le bloc de support comprenant une surface interne faisant face au transducteur, la surface interne comprenant une caractéristique non plane conçue pour augmenter l'absorption de signaux ultrasonores par le bloc de support.
