Abstract:
High-precision radiotherapy represented by stereotactic body radiation therapy(SBRT)plays an important role in every stage of lung cancer treatment.The development of medical imaging technology,more accurate dose calculation methods,and the application of advanced imaging and dose verification algorithms provide guarantee for the realization of high-precision radiotherapy.Four-dimensional computed tomography(4D CT)can better display the individualized motion of tumors affected by respiration.Four-dimensional cone beam computed tomography(4D-CBCT)is an image-guided technology to delineate and obtain the internal target volume(ITV),which Can provide guarantee for precise treatment.The combination of the two technologies can correct the displacement error,monitor the range of tumor motion,and ensure that the moving target is within the irradiation range,which is the guarantee of stereotactic radiotherapy.From the perspective of image-guided radiation technology in the application of precise radiotherapy for lung cancer,the clinical application value of 4D CT combined with 4D-CBCT in SBRT of tumors was reviewed,aiming to provide reference for clinical radiotherapy of lung cancer.
