ABSTRACT:
A computed tomography apparatus is described which enables an optimum examination of the small intestine region, having a patient support which permits a scan to be conducted of a patient with the patient in a substantially upright, but slightly tilted, position, and a control unit for maintain the gantry containing the x-ray source and detector at the same angle relative to said patient support for all positions of the patient support during a scan. A three-dimensional image reconstruction ensues such that, given a contrast agent fill of hollow organs, the hollow organ is computationally sliced, a contrast agent trunk is computationally removed and the inside of the hollow organ is thus displayed. The hollow organ can be displayed sliced in side-by-side images but can also be displayed in the form of an involution of its inside view.
