    Abstract: The embodiments relate to a CT system with a stationary part and a rotatable part, which is supported rotatably in the stationary part. At least one x-ray tube unit cooled by a cooling fluid, an x-ray detector lying opposite the x-ray tube unit, and a cooling device coupled in terms of fluid technology to the x-ray tube unit via a coolant circuit are disposed in the rotatable part. A cooling air channel, through which cooling air is able to be fed into the rotatable part, and an exhaust air channel, through which heated exhaust air is able to be taken away from the rotatable part, are disposed in the stationary part. In accordance with the embodiments, at least one overpressure relief valve is disposed in the coolant circuit, through which the cooling fluid is able to be conveyed away in the exhaust air channel.

    Abstract: An x-ray tube has a backscatter electron trap to prevent extra focal radiation caused by backscattered electrons from the focal spot from passing through the beam exit window to an exterior of the x-ray tube. The backscatter electron trap has a surface that faces the x-ray beam in the x-ray tube. No portion of that surface is visible both from an arbitrary point in the x-ray beam outside of the x-ray tube and from an arbitrary point at the focal spot.

    Abstract: A computed tomography system has a gantry with a rotor side that can be rotated around a system axis during operation, at which at least one x-ray tube is mounted. To cool the at least one x-ray tube a liquid cooling system is equipped with a fluid volume filled with cooling liquid, the fluid volume extends over distances of different sizes from the system axis. The fluid volume is located on the rotor of the gantry and thus is exposed to centrifugal force during operation. To increase pressure in the cooling system, a flexible compensation volume and a movable mass element that rotate with the gantry are provided. The mass element is arranged such that the centrifugal force acting on the mass element during operation causes pressure to be exerted on the cooling liquid.

    Abstract: A blank for forming a parallelepipedal box or a parallelepipedal box element is constructed with a removal strip in such a manner that parallel tear lines extend through three connected wall sections of the blank. The tear lines end in one wall section at an articulation area. The tear lines delimit the removal strip which can be torn out of a finished pack or box and upon which a pulling force can be exerted in such a manner that the removal strip is bent about the articulation area, thus causing objects to be lifted from the box by the removal strip.
