Abstract

A portable x-ray exposure apparatus carries all components required for the production of an x-ray exposure. Two articulated arms are provided at a carriage, one carrying an x-ray source and the other carrying a flat detector that is formed by a matrix of detector elements. Image signals from the detector are supplied to image electronics in the carriage. The x-ray image generated by the image electronics is reproduced on a monitor or is transmitted to image data networks. The flat detector can be inserted under the patient in the bed.

Claims

1. A mobile x-ray exposure apparatus comprising:

a manually movable portable carriage having non-motorized means for freely moving said carriage without any directional constraint;

an x-ray source and first articulation means attached to said portable carriage for mounting said x-ray source on said portable carriage for allowing three-dimensional position adjustment of said x-ray source;

a flat radiation detector comprised of a matrix of detector elements which emit image signals dependent on radiation from said x-ray source incident thereon;

second articulation means attached to said portable carriage separately form said first articulation means, for mounting said flat detector on said portable carriage for allowing three-dimensional position adjustment of said flat detector; and

image electronics, completely contained in said portable carriage, supplied with said image signals and emitting video signals, at an output within said portable carriage, produced from said image signals.

2. An x-ray exposure apparatus as claimed in claim 1 further comprising a plug on an exterior of said portable carriage connected to said output of said image electronics for supplying said video signals to a playback arrangement selected from the group consisting of a video monitor and an image data network.

3. An x-ray exposure apparatus as claimed in claim 1 further comprising a voltage generator completely contained in said portable carriage and connected to said x-ray source, said voltage generator having a mains terminal, proceeding from said portable carriage connectable to an external power source for supplying power to said voltage generator.

4. A mobile x-ray apparatus as claimed in claim 1 further comprising a voltage generator contained in said carriage and connected to said x-ray source, and a battery contained in said carriage and connected to said voltage generator for supplying power to said voltage generator, said battery having a mains terminal connectable to an external power source for recharging said battery.
