Quizplus · Accepted Answer

IGRT stands for Image-Guided Radiation Therapy, which uses imaging techniques such as CT, MRI, and PET scans to accurately locate the tumor and adjust the radiation beams accordingly. This helps to minimize the exposure of healthy tissues to radiation and increase the effectiveness of the treatment. IGRT also allows for gated treatment fields, which means that the radiation beams are turned on and off at specific times during the breathing cycle to reduce the likelihood of damage to the surrounding organs. Optical tracking of tumor location and size is another feature of IGRT, which can also contribute to a successful radiotherapy program. Therefore, all the given choices make IGRT an important part of a successful radiotherapy program.
