Deblurred Tomography Enhances the Image Quality

The blurring artefact may affect the computed tomography images due to various real world limitations. Such prevalent degradation is usually difficult to avert and it highly contributes in concealing important medical information that already exists in the image. 

Deblurring for Computed Tomography
As a consequence, the visual quality of the recorded images has been reduced tremendously. Then, different deblurring concepts have been introduced toaddress this ill-posed problem. The drawbacks with many of the contemporary deblurring methods are high complexity and processing times. Hence, a Gaussian prior deconvolution is adopted in this study because of its ability to provide an efficient and fast processing which is convenient for CT images. Intensive tests have been conducted to attest the validity of this algorithm, for which both naturally and synthetically degraded CT images are utilized. Furthermore, the quality of the synthetic data is measured.
