Claim Text:
1. An apparatus for aiding operation of an x-ray imager during an image acquisition procedure, the X-ray imager being configured to vary X-ray dosages depending on differences in X-ray attenuation levels across an object of interest to be imaged, the X-ray imager being further configured to assume any one of a plurality of imaging geometry positions when acquiring an image, the apparatus comprising: an input unit configured to receive a request to change a current imaging geometry position for an updated imaging geometry position for use in an image acquisition; a memory unit configured to store a function relationship between the plurality of imaging geometry position and the X-ray dosages, the function relationship being based on expected X-ray attenuation levels in the object of interest; and an output unit configured to use the stored function relationship to provide to an operator of the X-ray imager an indication of a relative change in X-ray dosage required at the updated imaging geometry position relation to the X-ray dosage required at a reference position.
