can be adjusted via a gantry lift drive 11 as noted above the gantry itself includes the x ray tube 15 and the x ray detector 14 the beam path between the x ray tube 15 and the x ray detector 14 is illustrated by an x ray beam 16 in this example the x ray beam 16 limits the diameter of a cylindrical measurement field 18 to a value that is smaller than that of the inner bore 17 of the gantry fig4 shows the x ray machine of fig3 in a different cross sectional view with wall 25 having a cut out wall portion 28 so that the breast locating means 40 is accessible at any set height as noted above an x ray machine for imaging a female breast comprises a gantry 10 that is rotatable about a rotation axis 12 mounted on this gantry is an x ray facility with an x ray tube 15 and also an x ray detector 14 the x ray tube 15 emits x rays along a direction towards the x ray detector 14 locating means 40 a and 40 b are disposed at ends of cylindrical measurement field 18 locating means 40 a and 40 b each serve to accommodate or locate a female breast for imaging the breasts the gantry rotates about the rotation axis at the same.
