According to one embodiment, an X-ray tube assembly includes a cathode includes a first non-magnetic metal member having high electrical conductivity, an anode target includes a second non-magnetic metal member having high electrical conductivity, a vacuum envelope having depressed portion depressed, and a first magnetic deflector provided outside the vacuum envelope, includes first magnetic pole pair generating the alternating magnetic field, the first magnetic pole pair being provided in close vicinity to a wall surface of the depressed portion.

A raster scanning x-ray source can be light and small, and can have high resolution. A raster-assembly can be attached directly to and can encircle an x-ray tube. The raster-assembly can adjoin or can be very close to the x-ray tube, resulting in a small and lightweight scanning x-ray source. X-rays can backscatter back into the x-ray tube instead of into a detector, thus improving resolution of the resulting image. A voltage-multiplier, which can be used with the x-ray source, can include separate voltage-multiplier-stages in a stack.

A method to adjust or tune mechanical settings of a mammography apparatus comprising an x-ray source, a paddle and a detector with a detector cover, wherein before executing an x-ray measurement a patient's breast is placed and compressed between the detector cover and the paddle, wherein prior to the x-ray measurement reaction forces between the mammography apparatus and the patient's breast are minimized. The invention relates further to a mammography apparatus comprising an x-ray source, a paddle and a detector with a detector cover, which apparatus is provided with at least one weighing means to measure the downwards forces exerted by (the part of) the apparatus above the weighing means towards the ground.
