摘要： An x-ray apparatus for mammography, with an x-ray tube having a tungsten, a filter downstream in the beam direction of the x-ray tube and a detector downstream from the filter, the detector being produced from a semiconductor material. To improve the quality of mammographic x-ray exposures as well as to simultaneously reduce the radiation dose, the filter is produced from a filter material having a K-absorption edge in the range between 3.8 keV and 7.3 keV.

摘要： Systems and methods are provided for generating X-ray pulses during X-ray imaging. A high voltage of an X-ray tube is automatically switched off. The tube voltage decays and upon reaching a predefined threshold value of the tube voltage or a predefined waiting time after switching off the high voltage, a grating voltage of a grating arranged between an emitter and an anode of the X-ray tube is automatically switched on. No electrons reach the anode from the emitter, and the tube current drops to the value zero.

摘要： A method and apparatus for determining an x-ray image data record of a target location subjected to a movement using an x-ray device. A number of basic images of the target location are recorded using a basic exposure time in each case and the x-ray image data record corresponding to an x-ray image with a longer exposure time is determined by combining basic images registered with one another. At least one quality value assigned hereto and relating to the movement in the target location during the recording is determined for each basic image and the contribution of a basic image to the x-ray image data record is determined as a function of the quality value.

摘要： A method for visualizing a dose of X-ray radiation applied to a surface of a patient in a defined time period by an X-ray apparatus is proposed. The X-ray apparatus is adjustable to different angular positions. A model of the surface of the patient is provided. The dose of X-ray radiation applied to the surface of the patient in the defined time period is calculated. The model and the calculated dose on the model is visualized. The visualization of the model and the calculated dose on the model is effected in an angular position coupled to the angular position in which the X-ray apparatus is currently disposed.

摘要： An X-ray radiation detector (100) consists of an arrangement with photodetector elements (12) and a scintillator layer (14) on the same. It is assumed in an exemplary fashion that the scintillator layer (14) subjects an input signal, which describes an object to be imaged, to a convolution with a modulation transfer function. The effect of this can be cancelled, particularly by obtaining a test X-ray image in advance, with the aid of which this modulation transfer function, or a similar variable providing information on the modulation transfer function, is established. If use is made of photodetectors that are based on CMOS technology, use can be made of a particularly thick scintillator layer made of gadolinium oxysulfide, which absorbs a particularly large amount of X-ray radiation. High-contrast X-ray images are obtained in this fashion.

摘要： To improve the quality of x-ray images, IN a method to process an x-ray image, a mathematical correction of the x-ray image is implemented, wherein the correction at least partially removes from the x-ray image the locally dependent blurring caused by a projection direction-dependent, effective optical focus size of an x-ray tube used to acquire the x-ray image.
