Query: Robust scatter correction method for cone-beam CT using an
  interlacing-slit plate   Cone-beam computed tomography (CBCT) has been widely used in medical imaging
and industrial nondestructive testing, but the presence of scattered radiation
will cause significant reduction of image quality. In this article, a robust
scatter correction method for CBCT using an interlacing-slit plate (ISP) is
carried out for convenient practice. Firstly, a Gaussian filtering method is
proposed to compensate the missing data of the inner scatter image, and
simultaneously avoid too-large values of calculated inner scatter and smooth
the inner scatter field. Secondly, an interlacing-slit scan without detector
gain correction is carried out to enhance the practicality and convenience of
the scatter correction method. Finally, a denoising step for scatter-corrected
projection images is added in the process flow to control the noise
amplification. The experimental results show that the improved method can not
only make the scatter correction more robust and convenient, but also achieve a
good quality of scatter-corrected slice images.
