Abstract: In order to make it possible for a patient to easily and safely mount a patient table in a manner which requires little effort, at least one, especially extendable and retractable and/or fold-up and fold-down step is integrated into a patient mounting aid in the inventive patient table. In the inventive method there is provision for the at least one step initially to be extended and/or folded down, then for a beginning of the examination to be automatically deter-mined and finally for the at least one step to be retracted and/or folded up again, depending on the determination of the beginning of an examination.

Abstract: An x-ray system HAS adjustable operating parameters with a dependency existing between different auxiliary types of equipment selectable for an examination and a suitable setting of the parameter. A control system of the x-ray system has a data input device to detect the used auxiliary equipment, a data storage device with data concerning the relation between each type of auxiliary equipment and an optimal setting of the parameters therefor, and an adjustment device for automatically adjusting the parameter dependent on the selection of the auxiliary equipment.

Abstract: Method for an x-ray arrangement for compensation of scattered radiation and x-ray apparatus The invention concerns a method for an x-ray arrangement comprising two x-ray systems (1, 2) for compensation of scattered radiation. In addition, the invention concerns an x-ray apparatus with two x-ray systems (1, 2) which respectively comprise an x-ray source (4, 5) and an x-ray detector (5, 7). An x-ray scattered radiation image based on the x-ray radiation (11) scattered on a subject (P) is acquired for at least one of the two x-ray systems (1, 2), given a definite positioning of the x-ray systems (1, 2) relative to one another. The acquired x-ray scattered radiation image is saved and used for subtraction from an x-ray image acquired with the x-ray system (1, 2) in order to compensate for the influence of the scattered radiation originating from the other x-ray system (1, 2) and to achieve an improved image quality.

Abstract: For the purpose of noise correction for an x-ray flat-panel detector (2) it is firstly provided that in the dark image—without radiation impinging on the detector panel (4)—the noise is recorded for the subareas of an active area (8) and from this, subarea-specific correction factors are determined by means of which the respective signal value of the respective subarea is corrected in imaging operation. A dark area correction factor (DF1, DF2) is also determined in each case from the noise of two dark areas (6) that are spaced apart with respect to each other. In order to determine subarea-specific signal correction factors (SK), each of the DA correction factors (DF1, DF2) is weighted with a subarea-specific weighting factor (g1, g2), in particular a distance factor (a). By means of said measure improved noise correction is achieved.

Abstract: For noise correction in connection with a flat-panel x-ray detector (2), noise signals of a dark area (6) are checked for deviations exceeding a specified threshold (g) which, if any are present, will be taken into consideration separately for calculating the correction factor derived from the noise signal. Image artifacts due, for example, to high-contrast objects such as, for instance, cardiac pacemakers or metallic implants, in the x-ray image will be avoided through this measure.

Abstract: Reliable and at the same time simple operation of a plurality of system components using only a single control element is guaranteed by means of the combination of a control lever (10) which can be swiveled manually and a rotational control unit (11) which can be rotated manually. Translatory control motions can be executed intuitively by means of swivel movements (16) of the control lever (10) and rotatory control motions can be executed intuitively by means of rotary movements (14) of the rotational control unit (11). The embodiment of the rotational control unit (11) in the form of a ring element surrounding the control lever (10), which can be can be adjusted by raising or lowering into different operating positions, associated in each case with a specific operating function, is particularly advantageous.

Abstract: The invention relates to a hospital bed (1) with a support part (2) for a patient, said bed being provided with a moveable holder with a display (6) and/or with sensors (10 to 12) for recording measurement data. Measurement data of the patient can be recorded at all times by means of the sensors (10 to 12). These values can be displayed by means of the display (6). By means of a connection (9) to a multimedia network, these values can be communicated from the hospital bed. An input device (16) can be used to record patient data directly at the hospital bed.
