[Measurement of the imaging dose for head and neck cancer by different image-guided methods].


OBJECTIVE To measure the imaging dose in the head phantom by different image-guided methods. METHODS The imaging dose was measured in a cylindrical phantom on a Varian Clinac iX linear accelerator equipped with EPID, OBI, CBCT using a PTW 0.6 cc ion chamber with UNIDOS E dosimeter. 2D images were acquired by two perpendicular fields (0 degrees & 270… (More)
