Improvement of dose calculation in radiation therapy due to metal artifact correction using the augmented likelihood image reconstruction

BACKGROUND: Metal artifacts caused by high‐density implants lead to incorrectly reconstructed Hounsfield units in computed tomography images. This can result in a loss of accuracy in dose calculation in radiation therapy. This study investigates the potential of the metal artifact reduction algorith...
