1. An apparatus for imaging biological tissue, comprising:

  • a table having a radiolucent and sonolucent window on which biological tissue may be positioned;

    an X-ray source movably disposed above the table that emits X-ray radiation;

    an X-ray detector movably disposed beneath the window to receive X-ray radiation emitted by the X-ray source that passes through the biological tissue, wherein the X-ray detector is synchronously movable with the X-ray source relative to the window to facilitate generating X-ray data to form an X-ray image;

    an ultrasonic transducer positioned adjacent the X-ray detector and acoustically coupled to the window, the ultrasonic transducer generating an ultrasound image of the biological tissue; and

    a drive assembly for moving the ultrasonic transducer through a predetermined path beneath the window while the biological tissue remains immobilized on the table, so that the ultrasonic transducer generates a plurality of ultrasound images of the biological tissue that are in registration with the X-ray image.
