Abstract: A method for multi-parametric x-ray fluorescence imaging with maximized detection sensitivity and minimized radiation dose for a biological/living sample (10) containing a first marker substance comprises the steps of irradiation of the sample (10) with x-ray radiation (1), with x-ray fluorescence (2) of the first marker substance being excited, spatially resolved detection of the x-ray fluorescence (2) of the first marker substance, and determination of a distribution of the first marker substance in the sample (10) from the x-ray fluorescence (2) of the first marker substance, wherein the sample (10) contains at least one further marker substance which is excited to x-ray fluorescence (2) by the x-ray radiation (1), wherein fluorescence lines (3) of the first and the at least one further marker substances are different, at least one of the first and the at least one further marker substances is coupled with active ingredient molecules and/or ligand molecules provided for a specific interaction with the samp

Abstract: A method for an x-ray fluorescence measurement, in which the presence of fluorescing target particles is captured in an object (1) to be examined and target particles that are present are localized in the object (1), comprises the steps of (a) producing an x-ray beam (2) by means of a source device (10), wherein the x-ray beam (2) extends through the object (1) in an x-ray beam direction parallel to a first projection direction, (b) irradiating the object (1) with the x-ray beam (2) at a multiplicity of scan positions in a first projection plane, wherein the scan positions are set by a scanning device (20), by means of which the source device and the object (1) are moved relative to one another, (c) detecting x-ray radiation, emitted from the object (1) in a plurality of spatial directions, at each scan position using a detector array device (30), which is securely connected to the source device (10), wherein the detector array device (30) comprises a multiplicity of spectrally selective detector elements (31

Abstract: A control device of a motor vehicle, for controlling and/or regulating at least the operation of an internal combustion engine, wherein, before the execution of at least one defined function and/or during the execution of at least one defined function, the control device demands operation of the internal combustion engine in a defined operating state, and wherein, as a function of the length of time for which the respective defined function has not been executed and/or as a function of the length of time for which a defined operating state of the internal combustion engine has not occurred, the control device determines a defined characteristic variable, on the basis of which the control device, in a temporally variable manner, determines different and/or variable measures for influencing the operating state of the internal combustion engine.
