Image Guided Radiation Therapy (IGRT) in India
Image guided radiotherapy (IGRT) or radiation therapy is a way of using X-rays radiation and scans (images) before and during radiotherapy treatment. The X-rays and scans show the size, shape and position of the cancer. Cancer doctors plan the radiotherapy to give a high dose to the cancer to get best results.
It is important that the radiotherapy field covers the whole cancer plus a border around it. This helps the radiotherapy to work as well as possible in treating the cancer. Cancer doctors try to give as low a dose as possible to the surrounding healthy tissue to reduce the risk of side effects.
Advantages of IGRT
There are several advantages to radiotherapy or radiation therapy:
More precise radiation doses can safely be delivered by cancer doctors to tumours or cancer cells with fewer side effects Reduced treatment toxicity.
