Abstract EN
Soft tissue images from portable cone beam computed tomography (CBCT) scanners can be used for diagnosis and detection of tumor, cancer, intracerebral hemorrhage, and so forth.
Due to large field of view, X-ray scattering which is the main cause of artifacts degrades image quality, such as cupping artifacts, CT number inaccuracy, and low contrast, especially on soft tissue images.
In this work, we propose the X-ray scatter correction method for improving soft tissue images.
The X-ray scatter correction scheme to estimate X-ray scatter signals is based on the deconvolution technique using the maximum likelihood estimation maximization (MLEM) method.
The scatter kernels are obtained by simulating the PMMA sheet on the Monte Carlo simulation (MCS) software.
In the experiment, we used the QRM phantom to quantitatively compare with fan-beam CT (FBCT) data in terms of CT number values, contrast to noise ratio, cupping artifacts, and low contrast detectability.
Moreover, the PH3 angiography phantom was also used to mimic human soft tissues in the brain.
The reconstructed images with our proposed scatter correction show significant improvement on image quality.
Thus the proposed scatter correction technique has high potential to detect soft tissues in the brain.
