Abstract:
1. A method for the repeated relative positioning of a patient in an imaging diagnostic and/or radiation-therapeutic system in relation to the coordinate system of the respective system, the method comprising: producing in a first session, at least two reference images of a patient or a part of the patient in at least two different camera positions and in different recording axes, producing current images in each subsequent session with the same camera settings, superimposing the at least two reference images with the same camera setting on at least two current images so that the differences between the images become visible, and changing thereafter the position of the patient in relation to one of the system and a diagnostic or therapeutic partial device of the system until the differences between the reference images and the current images, which are current in respect to the new position of the patient, are minimized.
