X-ray imaging apparatus and control method for the same

摘要

Disclosed herein are an X-ray imaging apparatus and a method for the same. The X-ray imaging apparatus includes a kernel function setter configured to set a scatter kernel function in response to a scatter component included in first X-ray image data detected by an X-ray detector, and an image data corrector configured to generate second X-ray image data obtained by performing scatter correction on the first X-ray image data using the scatter kernel function and data consistency. According to the X-ray imaging apparatus and the control method for the same, scatter correction is performed by using data consistency so that accuracy of the scatter correction may be increased and an X-ray image may be generated based on the accuracy, thereby improving quality of the X-ray image.

1. An X-ray imaging apparatus comprising:
a processor configured to set a scatter kernel function in response to a scatter component included in first X-ray image data detected by an X-ray detector and generate second X-ray image data obtained by performing scatter correction on the first X-ray image data by using the scatter kernel function and a data consistency; and a display configured to display an X-ray image reconstructed from the second X-ray image data, wherein the processor is further configured to generate corrected image data obtained by performing scatter correction on the first X-ray image data by using the scatter kernel function, determine whether a parallel-beam type corrected image converted from the corrected image data by performing fan-parallel rebinning satisfies the data consistency and determine whether to update the scatter kernel function based on a data consistency of the parallel-beam type corrected image data.
