摘要:
An apparatus aids operation of an interventional x-ray imager during image acquisition, where the X-ray imager is 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 is further configured to assume any one of a plurality of imaging geometry positions when acquiring an image. An indication, visual, acoustic or haptic, to the operator of the 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, while a given constant image quality is maintained throughout the different views.
