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.
