ABSTRACT
<p><b>OBJECTIVE</b>To research the method of dosimetric verification of the intensity modulated radiation therapy (IMRT).</p><p><b>METHODS</b>The IMRT treatment plans were designed by Eclipse TPS and were implemented in Varian ClinacIX LA with 6MV X-ray. The absolute point doses were measured using a PTW 0.6 cc ion chamber with UNIDOS E dosimeter and the planes dose distributions were measured using PTW 2D-Array ion chamber in the phantom.</p><p><b>RESULTS</b>The error between the measured dose and calculated dose in the interesting points was less than 3%. The points passed ratio was more than 90% in gamma analysis method (3 mm 13%) about the plane dose distribution verification.</p><p><b>CONCLUSION</b>The method of dosimetric verification of IMRT is reliable and efficient in the implementation.</p>
