Title:
IRRADIATION SYSTEM AND CALIBRATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2012/152809
Kind Code:
A3
Abstract:
Position errors of the flat-panel detector in the system of axes of the irradiation system relative to a predefined position which remain after, for example, a basic construction of the irradiation system are compensated, and thus the accuracy of the irradiation system is brought close, with almost any desired accuracy, to that accuracy that would have resulted if the flat-panel detector had subsequently also been precisely accurately adjusted mechanically, by a geometric correction of the irradiation raw image being carried out, such that a change in a projection of the irradiated object in the irradiation raw image owing to the position error is reduced or corrected.
