Updating the Planar Patterson-Parker Table for Ir-192 and Cs-137 Brachytherapy Sources Using the Most Recent TG-43U1 Recommended Dosimetric Parameters
Background: The Patterson-Parker table was created in 1934 to determine mg-hr required to deliver the prescribed dose to the treatment area. These tables were created using the dosimetric data for 226Ra that was determined in air and were utilized for dose calculations around implants with Ra-equivalent radionuclides such as 137Cs and 192Ir. Therefore, the differences of the tissue attenuation ...
متن کاملA New Approach for Heterogeneity Corrections for Cs-137 Brachytherapy Sources
Background: Most of the current brachytherapy treatment planning systems (TPS) use the TG-43U1 recommendations for dosimetry in water phantom, not considering the heterogeneity effects.Objective: The purpose of this study is developing a method for obtaining correction factors for heterogeneity for Cs-137 brachytherapy sources based on pre-calculated MC simulations and interpolation.Method: To ...
