abstract = "The ionizing radiation that propagates through the human body at
Computed Tomography (CT) exams is known to be carcinogenic. For
this reason, the development of methods for image reconstruction
that operate with reduced radiation doses is essential. If we
reduce the electrical current in the electrically powered X-ray
tubes of CT scanners, the amount of radiation that passes through
the human body during a CT exam is reduced. However, significant
image noise emerges in the reconstructed CT slices if standard
reconstruction methods are applied. To estimate routine-dose CT
images from low-dose CT images and thus reduce noise, the
Conditional Generative Adversarial Network (cGAN) was recently
proposed in the literature. In this work, we introduce the Gated
Recurrent Conditional Generative Adversarial Network (GRC-GAN)
that is based on the usage of network gates to learn the specific
regions of the input image to be updated using the cGAN denoising
operation. Moreover, the GRC-GAN is executed recurrently in
multiple time steps. At each time step, different parts of the
input image are denoised. As a result, our GRC-GAN better focus on
the denoise criterium than the regular cGAN in the LoDoPaB-CT
benchmark.",
