ABSTRACT:
A computed tomography scanner for obtaining a tomographic image of a subject to be examined including a radiation emitting device for emitting radiation in a shape of a fan beam to the subject, a radiation detecting device for detecting the radiation that has passed through the subject to obtain detection data with respect to a tomographic plane of the subject. The radiation emitting device and the radiation detecting device determines a scanning area constituting a data collection region in a radiation plane of the fan beam. The subject has external dimensions exceeding the scanning area. The computed tomography scanner further includes a scanning device for relatively moving the subject, the radiation emitting device and the radiation detecting device in a condition that the radiation plane and the tomographic plane are on a same plane and a device for obtaining the tomographic image of a part of the subject corresponding to the scanning area from the detection data obtained by the radiation detecting device.
