ABSTRACT:
A mammograph is made, wherein the X-ray tube and the work top are held facing each other by a stirrup, making it easy for an X-ray technician to reach the breast to be X-rayed. The stirrup is shaped like a ring and can rotate on itself in sliding on a complementary ring, so as to reduce the inertia of the movable masses, to bring about radiography under oblique or even horizontal incidence. Furthermore, the structure is preferably moved away from a control cabinet for the mammograph, to enable an X-ray technician to come between this cabinet and the patient so as to facilitate preparations for taking a picture.
