Abstract (en)

[origin: EP0396795A1] The invention relates to an X-ray diagnostic apparatus having a transmission chain (4 to 10) in which imaging errors occur and which has an X-ray image intensifier (4) and an optical device (5) for imaging the output image of the X-ray image intensifier (4) on an image recording device (8) coupled to the optical device (5). The optical device (5) has distortion which acts in the opposite sense to the imaging errors of the other elements of the transmission chain (4 to 10) such that the imaging errors of the transmission chain (4 to 10) are eliminated. <IMAGE>
