摘要：
A double focal spot X-ray tube is used to acquire a set of two images PIα, PIβ for a given gantry position from slightly different view positions. The stereo or binocular disparity (BD) of imaged structures is used to estimate the object depth in view direction, which in turn is used to discriminate between objects inside IO and outside EO the body. Respective structures are virtually removed from the images PIα, PIβ.
