Patent ID: 7810996

Claim:
A method for constructing a dual fluoroscopy system, comprising: providing a first c-arm and a second c-arm, wherein the first c-arm comprises a first x-ray generator and a first imaging device, and wherein the second c-arm comprises a second x-ray generator and a second imaging device; synchronizing exposure timing of the first x-ray generator and the second x-ray generator; decoupling the first x-ray generator and the first imaging device from the first c-arm and the second x-ray generator and the second imaging device from the second c-arm; mounting the first and second x-ray generators and the first and second imaging devices to a gantry system; aligning the first x-ray generator with the first imaging device and aligning the second x-ray generator with the second imaging device; and performing a calibration test to determine three-dimensional positions and orientations of the first and second x-ray generators and the first and second imaging devices.
