X-ray ct apparatus

An X-ray CT apparatus comprising:

• an X-ray irradiator configured to irradiate fan-beam X-rays;
• a multi-channel X-ray detector disposed to face said X-ray irradiator;
• a transmitted X-ray data collection device configured to collect transmitted X-ray data of two or more views by performing a scan of a subject while rotating said X-ray irradiator and said X-ray detector;
• a scan control device configured to control the scan;
• and
• an image reconstruction device configured to reconstruct an image based on the transmitted X-ray data, wherein said X-ray irradiator is configured to irradiate fan-beam X-rays deflected to one side of the center of rotation, said X-ray detector comprises a plurality of channels to cope with a spread of the fan-beam X-rays, said scan control device is configured to enable said X-ray irradiator and said X-ray detector to conduct a scan of at least one rotation.
