Conjugate gradient methods form a class of iterative algorithms that are highly effective for solving large‐scale unconstrained optimisation problems. They achieve efficiency by constructing search ...

In this paper, we presented a new three-term conjugate gradient method based on combining the conjugate gradient method proposed by Cheng et al [15] with the idea of the modified FR method [22]. In ...

Cone beam computed tomography (CBCT) is an imaging modality that has been used in imageguided radiation therapy (IGRT). For applications such as lung radiation therapy, CBCT images are greatly ...
