Abstract
Disclosed herein are a two-dimensional X-ray detector provided with a table of the position and size of a region-of-interest so as to change the position and size of the region-of-interest for each frame, and a cone-beam CT apparatus using the same and an operation method thereof. ROI projection data of a high resolution for a set ROI may be acquired, and the binning technique may be applied to non-ROI projection data created by the X-rays emitted onto a non-ROI region to acquire low-resolution data. Thereby, the amount of projection data may be reduced.
