Abstract: A coating system including at least one reactive resin system RH, at least one thixotropic assistant TH selected from the group consisting of urea preparations HZ and fibers FS and at least one inorganic aggregate AZ having a particle size in the range from 0.2 to 3.0 mm. The coating system has a viscosity as measured with a shear rate of 1 s?1 of 9000-100,000 Pas and a viscosity as measured with a shear rate of 100 s?1 of 400-15,000 Pas. The coating system is notable for high surface roughness and for reliable and long-term bonding of the aggregates to the coating with no need for sealing. There is also no need for the coating to be subsequently strewn with aggregates such as sand, for example.

Abstract: An imaging device is disclosed for generating successive tomograms of an object. In at least one embodiment, the imaging device includes a radiation source, a detector, a positioning unit and a control unit for controlling the positioning unit and for evaluating the recorded data of the detector. In at least one embodiment, it is provided that the control unit is set up for matching a contrast medium protocol, in which parameters for contrast medium administration are stored, provided for examinations in a contrast medium device, to a scan protocol provided for the examination, in which operating parameters for generating successive tomograms are stored, for preventing unnecessary administration phases.

Abstract: An operating method is disclosed for an X-ray machine for examining a patient by using a contrast agent in the case of which a preliminary examination is carried out for determining a contrast agent curve in the case of which a series of attenuation values relating to defined scanning instants are acquired at a set scanning position, the contrast agent curve being determined on the basis of the attenuation values, and being stored for a follow-up examination. The contrast agent curve can be loaded during a follow-up examination and need not be determined anew, and so a reduction is attained in the contrast agent used, the applied radiation dose and the examination time. The contrast agent curve can, furthermore, be adapted to the examination situation currently present by taking account of biosignals.

Abstract: A device and a method are for operating a computer tomograph and an injector, wherein an injector is used to control injection of a contrast medium and a computer tomograph to control a scanning process. Data regarding operation are transmitted between the computer tomograph and the injector via a data interface, especially in a reciprocal manner. The two devices reciprocally influence their operation, thereby reducing the strain imposed on a patient to be examined, increasing operational reliability and simplifying handling.
