Abstract

A puncturing needle holder is attached to a flat-panel x-ray detector such that it is visible in the x-ray image as a point. The point can involve the crossing area of two struts, which are attached to the flat-panel x-ray detector. Mappings are created in which on the one hand a region of the body to be punctured and on the other hand the point created by the puncturing needle holder are mapped by the x-ray images created with the flat-panel x-ray detector. The x-ray C-arm is moved until such time as precisely the puncturing needle holder is shown in the mapping so that it points to the region of the body to be punctured. Subsequent puncturing can then be carried out in a number of different ways.

First claim

The invention claimed is:

1. An X-ray C-arm system, comprising:
an x-ray source that emits x-rays;
a flat-panel x-ray detector with a flat surface;
a rotatable and tiltable C-arm on which the x-ray source and the flat-panel x-ray detector are disposed; and
a puncturing needle holder that is arranged on the flat-panel x-ray detector and extends in a straight line perpendicular to the flat surface and in a direction from the flat surface to the x-ray source;
wherein the punc…
