Patent ID: 8774484

Claim:
An X-ray apparatus, comprising: an X-ray imaging device; an arm for supporting the X-ray imaging device; and a controller for controlling a single injection of a contrast agent into an object, the X-ray imaging device and the arm, wherein the controller is adapted to control in a first phase a first movement of the arm while the single injection of the contrast agent is not finished, such that (i) the X-ray imaging device is moving along a first path in a forward direction (F) around the object, and (ii) a timing of the first movement and the single injection of the contrast agent overlap, wherein the X-ray imaging device is adapted to take a first plurality of images of the object during the first movement, wherein the controller is adapted to generate first volume data from the first plurality of images in which both hepatocellular carcinoma (HCC) and pseudo lesions show up as hyperattenuating lesions that may not be distinguished from one another; wherein the controller is adapted to control in a second phase a second movement of the arm, such that the X-ray imaging device is moving along a second path in a backward direction (B), wherein the X-ray imaging device is adapted to take a second plurality of images of the object during the second movement, and wherein the controller is adapted to generate second volume data from the second plurality of images in which HCC shows up as a ring-like enhancement which is not expected for pseudo lesions, allowing a distinction between the two with only one contrast agent injection.
