Abstract: In a method for acquiring a position of a region to be examined of an object for a medical imaging examination, a marker element is manually positioned at the region to be examined of the object, the position of the marker element is acquired by an acquisition apparatus, a feedback marking is projected at the acquired position of the marker element by a projection apparatus and based on a correction factor in the z-direction that is considered when ascertaining a projection position of the feedback marking, the acquisition of the position of the marker element and of the projection of the feedback marking is repeated until the feedback marking coincides with the position of the marker element, and the position of the marker element is defined as the position of the region to be examined of the object.

Abstract: An imaging apparatus has a tubular receptacle to receive an object to be examined by the imaging apparatus. The imaging apparatus has an air channel device configured to: draw air from the tubular receptacle at an intake device of the air channel device; guide drawn-in air through an air filter device of the air channel device for decontamination; and output decontaminated air into the tubular receptacle at an output device of the air channel device. The air channel device is configured to guide a main airstream of air along the tubular receptacle from the output device to the intake device. The main airstream flows through the tubular receptacle towards a receptacle opening of the tubular receptacle.

Abstract: A plasma filter device includes at least one electrode device. The at least one electrode device having a first composite electrode and a second composite electrode in a planar manner. The first and second composite electrodes are arranged coplanar to one another on a main surface plane of the electrode device and are separated from one another by a discharge gap. Each of the first and second composite electrodes has a respective electrode sheet that, at least on a boundary surface of the electrode sheet to the discharge gap, has a respective dielectric coating. The plasma filter device further includes a power source configured to provide an AC voltage to the electrode device. The AC voltage is parameterized to instigate formation of a plasma through a dielectric barrier discharge in the discharge gap.

Abstract: A cleaning unit for cleaning a housing of a medical imaging apparatus surrounding a patient receiving area, including at least one cleaning element, wherein the at least one cleaning element has an annular carrier structure, and a diameter of the cleaning element comprises at least one value of a diameter of the housing surrounding the patient receiving area.
