  Traditional craniospinal irradiation consists of a large treatment area divided into several fields that can create dose overlaps in the inter-field junction. This analysis compares the dosimetric parameter of craniospinal irradiation with HT, 3DCRT, and LINAC-based IMRT and find the optimal technique in terms of dose distribution, organ-sparing, and body radiation exposure. In our hospital, 3DCRT, IMRT, and HT plan were made from CT data of 10 patients indicated for craniospinal irradiation, with a total dose of 36 Gy in 20 fractions. Cranial and spinal PTV coverage was evaluated using the Conformity Index (CI) and Homogeneity Index (HI). Dose received by critical organs, body-wide radiation exposure, number of Monitor Units (MU), and beam on duration were recorded and compared. In cranial PTV, HT and IMRT had better HI and CI compared to 3DCRT with no significant differenc.. Read More»
