Method for the controlling of the taking of X-ray pictures at different occasions but of the same object, in particular skeleton parts, so that corresponding picture positions and picture angles are obtained, including the taking of two initial somewhat different pictures. The pictures are compared, and with as suggested a computer is calculating how a picture coinciding with the previous picture is to be taken. Advantageously Fourier analysis can be used to calculate correct picture angle and picture position. |
