초록
Couch consisting of carbon and acrylic material was irradiated with Gantry and thedose to the tumor was compared with Min, Max and Mean values. Novails Tx dedicated treatmenttable was irradiated with 6 MV and 10 MV, and the attenuation coefficient of the does accordingto the angle (0°, 140°, 180°) were compared and analyzed when transmitting the table. As a resultof comparing the dose values obtained in this paper, it was confirmed that the dose distribution tothe normal tissues in the carbon material table is narrower than the acrylic material. When theexperiment was conducted with 6 MV and 10 MV on the Novils TX, it was confirmed that the losswas the largest at 140° due to the density of the table. It is considered that the treatment effect willbe better with the correction because the treatment is performed without the correction accordingto the angle when the usual radiation treatment is performed.
