Abstract
A bi-plane x-ray diagnostic apparatus has two x-ray tubes and two radiation receivers for respectively obtaining images from an examination subject in two different planes. Both x-ray tubes are fed by a single high-frequency generator, having a common chain therein including an intermediate DC voltage circuit, an inverse rectifier and a high-voltage transformer. Emission of x-rays from each of the x-ray tubes ensues via pulses supplied to control grids in the respective x-ray tubes. The operating parameters and the dose can be independently set for the respective images in the two planes.
