METHOD AND SYSTEM FOR THE PLANNING OF IMAGING PARAMETERS

摘要

The invention relates to a method and an assistance system (20) for the planning of geometrical imaging parameters like the active dose-measuring-field (29) and/or the opening of a collimator (12) of an X-ray device (10). An optical image (27) of a patient (1) on a table (2) is generated by a camera (21) and transferred to a computer (25). The computer (25) then overlays said optical image (27) of the patient (1) with a graphical representation of the geometrical imaging parameters, for example with a drawing of the available and/or activated dose-measuring-fields (28, 29). The user may thus control and interactively select values of the imaging parameters on the overlay image.
