An accurate way to do radiation dose assessment is with the help of realistic phantoms. For fabrication of the phantom various anatomical structures were delineated on CT images. The electron density of the materials chosen for fabrication was based on HU to electron density calibrations. The CT numbers of the phantom materials and those of the delineated regions on the patient CT were sampled using the Eclipse planning system and indicates agreement. The doses measured with the TLDs were compared with TPS calculated dose in different locations in the phantom like point A, bladder, rectum, left and right femoral head for ICBT treatment planning. The fabricated phantom is a representative female pelvis, realistic in density, size and anatomy and suitable for the evaluation of cervix cancer brachytherapy treatments. The dosimetric measurements confirm the suitability of the fabricated phantom for the verification of dose delivery in brachytherapy of carcinoma cervix.
