In computed tomography imaging, the computationally intensive tasks are the pre-processing of 2D detector data to generate total attenuation or line integral projections and the reconstruction of the 3D volume from the projections. This paper propose

Metal artifacts are increasingly prevalent in CT reconstructed volumes due to the presence of implants in the aging population. High degree of beam hardening in severely attenuating objects is one of the main contributors of strong metal artifacts. I

Due to wide cone angle, the artifacts caused by scatter radiation are inevitable in flat detector CT reconstructed images. Cupping and streak artifacts are the main manifestations of scatter artifacts which will degrade low contrast resolution and Ho

The polychromatic X-ray spectrum and the energy-dependent material attenuation coefficients generate beam hardening artifacts in CT reconstructed images. The artifacts can be corrected by projection linearization using polynomials. Recently, consiste

This work aims at the compensation of beam hardening artifacts by the means of an extended three-dimensional polychromatic statistical reconstruction to be applied for flat panel cone-beam CT.We implemented this reconstruction technique as being intr

The polychromatic X-ray spectrum and the energy-dependent attenuation coefficients of the imaged object introduce beam hardening artifacts in CT reconstructed volumes. Cupping, streak, and spill-over are the different manifestations of beam hardening

The polychromatic X-ray spectrum and the energy-dependent attenuation coefficient of materials cause beam hardening artifacts in CT reconstructed volumes. These artifacts appear as cupping and streak artifacts depending on the material composition an

Due to polychromatic nature of the X-ray spectrum, beam hardening artifacts are introduced in cone beam computed tomography reconstructed images. To reduce these artifacts, projection images can be linearized with higher order polynomials. Polynomial

In Digital Breast Tomosynthesis, a 3D representation of the breast is reconstructed from low-dose projection images acquired over a limited angular range. Each such image contains high level of noise which is often counteracted by a projection binnin
