1. An imaging system to facilitate radiotherapy delivery during a radiotherapy procedure comprising:
an imaging radiation beam emitter mounted in the system to be in line with an isocenter at which a target is disposed, wherein the imaging radiation beam emitter is configured to revolve about a first axis intersecting the isocenter;
an imaging radiation beam detector unit mounted in the treatment system opposite the imaging radiation beam emitter, wherein the detector unit is movable independently from the beam emitter; and
a control unit operably coupled with the imaging radiation beam emitter and detector, the control unit being configured to:
obtain a first image with the imaging radiation beam emitter and detector at a first position of the emitter; and
obtain a second image with the imaging radiation beam emitter and detector at second position of the emitter.
