The present invention relates to an apparatus for an ultrasonic examination of a deformable object, particularly, the breast. More particularly, the present invention relates to an apparatus capable of performing an ultrasonic examination by moving an ultrasonic probe while maintaining the position and shape of a deformable object to be inspected. That is, the present invention relates to an apparatus capable of performing an effective ultrasonic by scanning an entire deformable object such as the breast at one time using a movable ultrasonic probe. The apparatus of the present invention comprises a supporting frame a movable means which has a flat surface with rigidity widthwise on which the deformable object is placed and is installed in the frame to move forward and rearward at a certain moving distance in a longitudinal direction of the frame a driving means for moving the movable means forward and rearward and at least one ultrasonic probe disposed to extend widthwise of the movable means, a ultrasonic wave transmission/reception surface of the ultrasonic probe being substantially flush with an upper surface of the movable means, the ultrasonic probe being fixed to the movable means at a position inward form longitudinal both ends of the movable means by a distance smaller than the moving distance of the movable means.Linvention concerne un appareil destiné à lexamen aux ultrasons dun objet déformable, en particulier du sein. Plus particulièrement, linvention concerne un appareil capable deffectuer un examen aux ultrasons par déplacement dune sonde ultrasonore, tout en maintenant la position et la forme dun objet déformable à inspecter. En conséquence, linvention a pour objet un appareil capable deffectuer un examen aux ultrasons efficace, par balayage dun objet entièrement déformable, tel que le sein, à un moment déterminé, au moyen dune sonde ultrasonore mobile. Lappareil selon linvention comprend un cadre support, des moyens mobiles présentant une surface pl
