Apparatus (10) is provided that combines mammography equipment with an ultrasonic transducer (16) to generate ultrasonic images of the internal structure of breast tissue that are in geometric registration with a mammogram. The apparatus includes a radiolucent and sonolucent compression plate (15), and in alternative embodiments, a gantry driven ultrasound transducer (16) or a phased array ultrasonic transducer. Methods are provided for generating a mammogram and a plurality of corresponding ultrasound images without moving the breast between the mammogram exposure and the ultrasound imaging. Methods are also provided for viewing and analyzing the ultrasound images. Apparatus and methods are also provided for enhancing X-ray images obtained from conventional mammographic systems, and with reduced overall X-ray dosage to the patient.
L'invention porte sur un appareil (10) qui combine un mammographe et un transducteur d'ultrasons(16) et qui produit des images ultrasonores de la structure interne du tissu mammaire qui géométriquement enregistrée avec le mammograme. L'appareil comprend une plaque de compression (15) perméable aux rayons x et aux ultrasons, et dans les autres modes de réalisation, un transducteur d'ultrasons à support mobile (16) ou un transducteur d'ultrasons à déphasage. Les méthodes fournies permettent de produire un mammograme et les nombreuses images ultrasonores correspondantes sans déplacer le sein entre la mammographie et l'imagerie ultrasonore. Les méthodes fournies permettent aussi de visualiser et d'analyser les images ultrasonores. L'appareil et les méthodes permettent également d'améliorer la qualité des images radiographiques obtenues à l'aides des mammographes classiques, ce qui réduit la dose de rayonnement globale reçue par le patient.
