Abstract
A detection device for detection of an object in up to three dimensions by means of x-ray radiation in directions of detection differing from each other.
The invention relates to a detection device for detecting an object in up to three dimensions with an x-ray source and a detector for the x-rays arranged in a detection plane, which is arranged and embodied so as to detect the x-rays and to create at least one 2D dataset which represents the object in a projection through the object onto the detection plane. The detection device 1 also features a C-arm connected to the x-ray source and to the detector and a control facility effectively linked to the C-arm, which is embodied to move the C-arm, depending on a control signal received on the input side, in at least two or three rotational degrees of freedom and to hold it in a detection position represented by the control signal. The detection device is embodied to create a 3D data set which represents the object in three dimensions, especially in a overhead view or a section, and to output this together with the at least one 2D dataset for reproduction by means of at least one image display unit. The detection device features a position memory for position datasets, which each represent a detection position and, depending on a user interaction signal, can read out at least one position dataset from the position memory and create a control signal corresponding to the position dataset representing a detection position for moving the C-arm into the detection position and create a 2D dataset there by means of the detector.
