Abstract
Cone-beam computed tomography (CBCT) is an emerging medical imaging modality used for various clinical applications. However, radiation dose to patients is a major limiting factor for its utility in some applications such as daily patient setup and future adaptive therapy in radiotherapy. In this article, we summarize recent development for dose reduction in CBCT. In particular, we discuss several noise reduction strategies for low-dose CBCT with a low mAs protocol.
