Abstract
Traditional Radiotherapy basically use of anatomical surface landmark as well as its radiological correlation with the help of X ray imaging is basically known as 2-D planning, but in modern era of radiotherapy planning IGRT has its impactful role in radiotherapy like IGRT full benefits exploited when large organ motions and setup errors likely to occurs, All patients treated with conformal radiotherapy IGRT/SBRT should be theoretically get benefited, Clinical situations where low dose radiotherapy requires for tumor control or palliative radiotherapy or for superficial tumors are likely to get least benefit by IGRT treatment. Major concerns with IGRT are given below.
1-Limited availability of experience staff is a major concern.
2- In terms of quality control decision whether to go with new plan or continue with original plan.
3- Daily online treatment imaging of patient before treatment makes unnecessary radiation exposure is a threat for development of second malignancy.
4-Solutions for point number 3 ionizing radiation exposure is now being solved with the development of MR-LINAC.
Keywords: IGRT, IGRT Major concerns, IGRT benefits.
