Introduction: The accurate delivery of dose to the clinical target volume in radiotherapy can be affected with many different factors. With increased interest in 3-D conformal therapy and also in the context of multicenter clinical trials, it is necessary to provide standard techniques to assure quality in delivering treatment. An anthropomorphic phantom can be employed to verify the quality and consistency of treatments by mimicking the many steps involved in a radiotherapy process.Material and Methods: An anthropomorphic pelvic and cervix phantom was designed and fabricated to be used for imaging, treatment planning, and dosimetry application in the treatment of cervical cancer. The phantom was made of mm acrylic plates and each plate was machined and modeled based upon CT slices from a patient study. Most of the phantom was made of acrylic while contours of femur and the vertebral column were filled with appropriate materials. The CT numbers from patient images were used to adjust the composition of bone equivalent material. During the simulations, a Foley catheter and a rectal tube filled with a proper contrast agent were used to distinguish bladder and rectum from the remainder of the phantom. A23323 PTW intra- cavitary chamber which was cross calibrated against a NE 2581 ionization chamber was placed in special holes machined in phantom for dosimetry applications. The dose delivered to the isocenter (cervix), bladder and rectum were calculated using a 2D Plato treatment planning system and were compared with measured values.Results: The phantom is to be used to evaluate the consistency of a range of processes in radiation therapy, simulation, planning and delivery of treatment for cervical cancer.Conclusions: The objective of this study is to use the phantom to verify the accuracy and consistency of treatments in one institution and in national collaborative clinical trials, during acceptance testing of treatment planning systems and as an educational tool, for dosimetric research problems and for QA in radiation treatment of cervical carcinoma.
