The invention relates to a method and device for imaging a cyclically moving organ of a human or animal body, with a device supported such that it can be rotated at an angular velocity around the body recording images of the organ from different angle positions, with the angular velocity being modulated with a reference signal representing the movement phase of the organ. During the rest phase of the organ images of the organ are recorded at nominal angular speed. In the movement phase of the organ the device is slowed down, turned back and accelerated again such that on entry into the next rest phase the device records images for the next angle range at nominal angular velocity without major angle gaps in respect of the previous angle range, to generate the most complete data record possible.

Method and device for imaging an organ

The invention relates to a device for guiding at least one cable between a first system component connected to the cable and a second system component which is relatively rotatable and/or displaceable with respect to the first and is connected to the cable, whereby the cable exhibits a cable modality which can be changed by displacement and/or rotation of the second system component, whereby at least one device for adapting the cable modality is present. By making available a guide medium which allows the device for adapting the cable modality to be guided according to the displacement and/or rotation of the second system component, it is possible to provide a device which supports a mobile device without the function of the device being restricted by the cable guide.

Device for guiding a cable

Method for operating a medical examination apparatus, having an image recording device, which is moved in a rotary motion through a predetermined angular range around the patient in order to produce image recordings of a periodically moving object, with several runs being carried out by the image recording device in order to produce the image recordings and the start of the individual runs being initiated as a function of a reference signal, which represents a current movement status of the organ to be mapped, such that image recordings are produced at different radiation angles with each run.

Method for operating a medical examination apparatus and an examination apparatus associated therewith

The invention relates to an X-ray device, in which an X-ray source and an X-ray detector are attached, in an opposed arrangement oriented toward a rotational axis, to a common holder capable of rotating about the rotational axis. To simplify the design of the X-ray device, it is proposed that the holder is attached to the hand of a robot displaying six axes of rotation.

X-ray device

The invention relates to a method and a device for executing the method for spatial presentation of a predeterminable area under examination. By overlaying a movement of the axis of projection along an axis of examination onto a rotation of an axis of projection around the object under examination, and by interpolating from the recorded projection data sets image data sets for axes of projection not recorded, and by creating a spatial presentation of the area under examination from the projection and image data sets, a method and a device can be provided which increases the speed of an examination for an extended area under examination of an object under examination.
