摘要： An apparatus for calibrating or validating performance of a computed tomography (CT) scanner including a first element having a first diameter, a second element having a base structure and a first set of test objects that can be coupled to the base structure and separated from one another by a first set of distances. The apparatus also includes a third element having a second diameter and a first length, a fourth element having a first face and a second face parallel to one another with a first depth defined there between. The fourth element can include: a first cavity depressed a second depth into the first face, a fifth element including a plurality of wire pairs and disposed within the first cavity, a second cavity depressed into the first face such that a third depth is defined between a back wall of the second cavity and the second face, a sixth element including a first plurality of holes and a first thickness, the sixth element disposed within the second cavity, and a seventh element including a second plurality of holes and a second thickness, the seventh element disposed on the first face. A center of the first element, the second element, the third element, and the fourth element, respectively, are be aligned along a first axis.
