Fraction-variant beam orientation optimization for non-coplanar IMRT
Daniel O'Connor, Dan Nguyen, Dan Ruan +2
Conventional beam orientation optimization (BOO) algorithms for IMRT assume that the same set of beam angles is used for all treatment fractions. In this paper we present a BOO for…
Fast non-coplanar beam orientation optimization based on group sparsity
Daniel O'Connor, Yevgen Voronenko, Dan Nguyen +2
The selection of beam orientations, which is a key step in radiation treatment planning, is particularly challenging for non-coplanar radiotherapy systems due to the large number o…
Motion Compensated Dynamic MRI Reconstruction with Local Affine Optical Flow Estimation
Ningning Zhao, Daniel O'Connor, Adrian Basarab +3
This paper proposes a novel framework to reconstruct the dynamic magnetic resonance images (DMRI) with motion compensation (MC). Due to the inherent motion effects during DMRI acqu…
