METHOD FOR INTENSITY MODULATED RADIATION TREATMENT USING INDEPENDENT COLLIMATOR JAWS

The present invention is a method for treatment planning and delivery of the radiation treatment plan for the intensity-modulated radiation therapy (IMRT) treatment using linear accelerators (LINACs) not equipped with a multileaf collimator (MLC). The present invention makes the use of a simpler collimator consisting of only 4 collimator jaws. In addition, the method for treatment planning of the present invention may be performed on a computer separate from the LINAC control computer, so that the treatment planning system can generate IMRT treatment plans for LINACs and collimator jaws from different vendors.
