Multi-frame-based Cross-domain Image Denoising for Low-dose Computed Tomography. (arXiv:2304.10839v1 [eess.IV])

Computed tomography (CT) has been used worldwide for decades as one of the
most important non-invasive tests in assisting diagnosis. However, the ionizing
nature of X-ray exposure raises concerns about potential health risks such as
cancer. The desire for lower radiation dose has driven researchers to improve
the reconstruction quality, especially by removing noise and artifacts.
Although previous studies on low-dose computed tomography (LDCT) denoising have
demonstrated the effectiveness of learning-based methods, most of them were
developed on the simulated …
