Imaging at the treatment machine, before each session, confirms the target is exactly where the plan expects — correcting for the small day-to-day shifts in the body's anatomy.
A precise plan is only as good as the set-up that delivers it. IGRT is the verification step that makes high-precision radiation trustworthy day after day.
Before (and sometimes during) treatment, imaging is taken on the treatment machine and compared with the plan. If the anatomy has shifted — as it naturally does from day to day — the position is corrected before the beam is switched on.
IGRT is not a separate course of treatment — it is the precision layer applied within IMRT, SBRT, SRS and other techniques, adding only moments to each session.
Before each session, imaging at the treatment machine confirms the target is exactly where the plan expects, and the position is corrected if it has shifted.
Organs move slightly from day to day with breathing, bladder filling and bowel gas. Daily imaging means the dose lands where it was planned rather than where it was assumed.
The imaging dose is small and is accounted for in the plan. The accuracy it buys outweighs it.
