Abstract:
An x-ray diagnostic device comprising:an x-ray source which emits a conical x-ray beam; a positioning device adapted to receive an examination subject disposed in said x-ray beam; a two-dimensional radiation detector disposed opposite to said x-ray source for detecting x-rays emitted by said x-ray source and attenuated by said patient, said radiation detector emitting electrical signals dependent on said attenuation; a mechanism for rotationally oscillating said x-ray source and said radiation detector around a system axis; a linear displacement mechanism for effecting an uninterrupted linear displacement between said x-ray source and said radiation detector, and said positioning device, substantially along said system axis while said x-ray source and said radiation detector are rotationally oscillating around said system axis; and an image computer supplied with said electrical signals from said radiation detector or reconstructing an image of said examination subject from said signals.
