Abstract: A computer-implemented method is for determining at least one main acquisition parameter determining a dose of x-rays to be emitted from an x-ray emitter during image acquisition using an x-ray emitter and an x-ray detector. A first image data of a first preparatory image is evaluated to determine if a repeat condition is fulfilled and/or to determine the main acquisition parameter and/or at least one second preparatory acquisition parameter. The first preparatory image is acquired by the x-ray detector using at least one first preparatory acquisition parameter to control the x-ray emitter. In all cases or when the repeat condition is fulfilled, the main acquisition parameter is determined depending on second image data of a second preparatory image, acquired by the x-ray detector after the first preparatory image while at least one second preparatory acquisition parameter is used to control the x-ray emitter.

Abstract: A method is for positioning an imaging-relevant component of an imaging apparatus in an application-appropriate position for recording medical image data from a target region of a patient. In an embodiment, the method includes: acquiring information on the target region of the patient, acquiring a position of the patient relative to the imaging-relevant component, determining an application-appropriate position of the imaging-relevant component, determining a positioning instruction, and outputting the positioning instruction. An imaging apparatus of an embodiment includes an imaging-relevant component. The imaging-relevant component has a mechanical guide configured to position the imaging-relevant component along at least one degree of freedom of movement relative to a static arrangement of the imaging apparatus and/or a patient.

Abstract: At least one example embodiment provides a method for automatic positioning of an X-ray source of a medical X-ray system with a mobile X-ray detector. The method includes determining an examination region of the examination object, acquiring a position and a location of the examination object and the examination region by way of an optical position determining system, localizing the examination region, ascertaining a field point of the central ray of the X-ray source and a collimator size of the X-ray source based on the localized examination region, and automatic positioning of the X-ray source based on the field point and the collimator size.

Abstract: A method is described for positioning of an examination object for an imaging method. The method is used to record an external image of externally visible features of the examination object. The recording of the external image is used as the basis for determining a position and/or orientation of at least one part of the examination object assigned to the imaged features. Subsequently, a check is performed as to whether the determined position and/or orientation of the at least one part of the examination object conforms to a reference position and/or reference orientation. Finally, if the determined position and/or orientation of the at least one part of the examination object does not conform to the reference position and/or reference orientation, the position and/or orientation of the at least one part of the examination object is corrected. Also described is an object-positioning facility. Furthermore, an imaging medical facility is described.
