The Application Status and Development Trends of MRI-Guided Radiotherapy
The accuracy of radiation therapy is influenced by factors such as target area delineation,positioning errors,inter and intra organ movements.In recent years,with the continuous development of medical technology,the accuracy of radiation therapy has made significant progress,especially the application of image guided radiation therapy(IGRT),which effectively reduces the uncertainty of various influencing factors.MRI guided radiation therapy(MRIgRT)replaces cone beam CT(CBCT)with MRI,utilizing the unique imaging advantages of MRI to track tumor movement and biological changes online and in real-time,achieving adaptive radiation therapy(ART),which is an important technological advancement in the history of radiation therapy.This study provides a review of the current application status and development trends of MRIgRT.
