This article reports on the dosimeter of anew N-isopropanol acrylamide NIPAM, high weight percent T%, %C the mass percent of all comonomerpolymer gel formulation (6T%, 20C%), optimized for magnetic resonance imaging(MRI). The aim to investigated MR-based polymer gel dosimeter as a three-dimensional 3Ddosimeter in IMRT. Magnetic resonance spin-spin relaxation rate images were acquired and, aftercalibration, converted to absorbed dose distribution. The dose maps were compared with the dosedistribution calculated using ion chamber in one plan and radiographic film for two plans. Thedosimeters were irradiated by 4, and 10MV photons for doses in the range (4–10) Gy. The multiechosequence was used for the evaluation of T2 (spin-spin relaxation times) in the irradiated geldosimeters. (%dd) percentage depth dose for (IMRT) intensity modulated radiation therapy /polymer gel & Magnetic resonance imaging = 5.7% at 5cm, other the average dose are 10.45 fordose profile, where %dd percentage depth dose for (IMRT) intensity modulated radiation therapy/ionization chamber and radiographic film(IC&RF) = 4.6% at 5cm other the average dose are 10.45for dose profile. DVH dose volume histogram for polymer gel & magnetic resonance imaging = 94%, but DVH dose volume histogram for point by point ionization chamber and radiographic film = 86%.which lessince timing for protocol of integral part of verification radiation therapy. %U https://icmep.journals.ekb.eg/article_29630_aa585e2932c4f2943d52a3ecd0c59c90.pdf
