Protocol for marker-guided gated volumetric-modulated arc therapy.
The protocol consists of two steps—pre-treatment and in-treatment. (a) Pre-treatment: patient alignment and image guidance are performed. If alignment is significantly out of range at each procedure, patient alignment is performed again. (b) In-treatment: after delivering the first arc dose, the half-time fiducial markers are verified.
