Abstract: The present invention relates to a stereo tube radiation imaging system in which radiation emitted from each radiation source covers a different area of the detector surface. Furthermore, the present invention relates to a stereo tube imaging method wherein both radiation sources are operated independently and each cover part of the detector surface area. This is advantageous in that it may reduce radiation dose compared to known stereo tube imaging and introduces new possibilities for stereo tube imaging, such as improved object tracking within a body.
