Abstract:
With rapid developmerit of technology of three dimensional conformal radiotherapy(3DCRT)and intensity-modulated radiotherapy(IMRT),the immobilization and repetition of patients'treatment position need is more accurate.The setup errors of thoracic cancer patients are great because of the breathing motion of lungs.The method of utilizing CBCT(cone beam computered tomography)to verify and correct setup errors is convenient and effective.CBCT,as one way of imaging guided radiation therapy(IGRT),is directly fixed on linear accelerator,has an important role and broad application prospects in reduction of setup error.
