Abstract:
1. A mobile X-ray diagnostic machine for generating 2D X-ray projection images for a volume reconstruction, comprising: a C-arm capable of multiple motorized movements; an X-ray source, an X-ray receiver unit, wherein the X-ray source and the X-ray receiver unit are arranged on the C-arm; a control and image processing computer; and a travel stand which can travel over a floor, wherein the travel stand comprises a reference body, a position detection system connected to the reference body, said position detection system comprises a laser detection system, a path measuring system, and an inclination sensor, said laser detection system is arranged on the reference body and is adapted to determine a position of the reference body in a spatially fixed system of coordinates and relays the position of the reference body to the control and image processing computer to calculate a particular X-ray projection geometry, said path measuring system is capable of determining a position of the travel stand in relation to the floor, said inclination sensor is adapted to determine an inclination of a reference surface of the travel stand.
