How does IGRT work?
Before the radiation beam is turned on, physicians use Image Guidance technology to provide precise and exact information on the specific location of any soft-tissue or bony target. This will allow delivery of treatment to a specific site/tumour while avoiding surrounding healthy tissues. That means less damage to healthy tissue, less “collateral damage.”
With most types of IGRT, the radiographers can take scans using the radiotherapy machine. This can be done before, during or after each treatment. This allows them to verify that the “target’ is within the planned treatment field. It is also used to ensure that the other organs have not “moved” into the treatment field especially the rectum and bladder in prostate radiotherapy.
