摘要
A computed tomography apparatus has a radiation source from which a beam is emitted which has a fan angle and can be moved about a system axis within a measuring field defined by the fan angle in order to scan an object under examination, and a detector system for detecting the radiation from the radiation source and which supplies output signals corresponding to the received radiation, which are fed to a computer. From these output signals, the computer reconstructs images of the object under examination with reference to a reconstruction field which is larger than the measuring field.
