Fixed-beam radiotherapy systems with subjects rotating about a longitudinal
(horizontal) axis are subject to gravity-induced motion. Limited reports on the
degree of this motion, and any deformation, has been reported ...
Fixed-gantry cone-beam computed tomography (CBCT), where the imaging hardware is
fixed while the subject is continuously rotated 360° in the horizontal position,
has implications for building compact and affordable ...

PURPOSE: Compared to conventional linacs with rotating gantries, a fixed-beam
radiotherapy system could be smaller, more robust and more cost-effective. In
this work, we developed and commissioned a prototype x-ray ...
