ABSTRACT:
A method for automatically setting a collimator of an x-ray imaging system during image acquisition includes receiving rapid scout images at an imaging station. The location of the body regions in one of said images is then automatically detected. The detected location of the body regions is used to generate settings for the collimator. The settings are used for automatically adjusting the collimator to substantially cover the non-body regions and substantially expose the body regions.
