IGRT :
Image-Guided Radiation Therapy is a treatment for cancer. It is a form of radiation therapy that can destroy cancer cells and shrink tumours. IGRT is typically used to treat cancerous tumours in a part of the body that moves during treatment. For instance, it is used to treat tumours in the lungs.
IGRT is performed with the help of a linear accelerator (LINAC) machine. The machine generates high-energy X-rays and directs them at the prescribed location of the tumours. The machine does not touch the body of the patient. IGRT is used to treat cancers such as lung cancer, brain cancer, abdominal cancer, prostate cancer and gynaecological cancers. Before the procedure, a radiation oncologist will take several scans of the body, including highly accurate measurements of the tumour using laser lights. Then, the dimensions and location of the tumour is fed into the LINAC machine and the treatment begins.
