REAL TIME FEEDBACK FOR PREVENTING HIGH DOSE C ARCH GEOMETRY POSITIONS

摘要

The present invention relates to an apparatus for aiding operation of an interventional x ray imager during image acquisition to a method of aiding operation of an x ray imager to an interventional x ray imager to a computer program element and to a computer readable medium. The X ray imager is capable of varying X ray dosages depending on differences in X ray attenuation levels across an object of interest to be imaged and is capable of assuming any one of a plurality of imaging geometry positions when acquiring an image. An indication visual acoustic or haptic to the operator of an X ray imager is provided on the incurred change in X ray dosage when changing from a current projection view to an updated projection view provided that a given constant image quality is to be maintained throughout the different views.
