Same as Cone-beam CT, this is a method reconstructing tomography image using projection image gained by rotating inspection object 360°after placing the object between X-ray generator and detector. Only single tomography image can be gained, not 3D volume image by single rotation like Cone-beam CT. This is theoretically accurate algorithm unlike Cone-beam CT and can reconstruct very accurate image without error according to scanning. Also, better quality of section reconstruction image can be gained by efficiently reducing the effect of Scatter if appropriate collimator is used. However, as only single section image can be gained by single rotation, many rotations are needed for 3D reconstruction and this means that longer scanning time than Cone-beam CT is necessary. Scanning time can be reduced by applying Helical Scan.
