Abstract: (181 Views) |
Background: The successful installation of linear accelerators (LINACs) depends on operator skill and experience, and its optimization can be further improved using vendor commissioning support. To facilitate the introduction of LINAC, Elekta provides commissioning support through Accelerated Go Live (AGL) using representative beam data. This study aimed to evaluate the effective commissioning of LINAC-assisted AGL complemented by additional measurements conducted by a user. Materials and Methods: Output doses were measured within a field size of > 3 cm2 using a single chamber with AGL and within a field size of > 2 cm2 using three types of optimal chambers based on the field size adopted by the user. In all cases, the differences between the measured and calculated output doses were maintained at < 2%. Results: The accuracy of couch modeling was evaluated by measuring arc irradiation for three different field sizes, with the electron density value assigned as a dose difference of <2% between the measured and calculated values at 2% for all energies and field size of >3 cm2. Additionally, imaging scan parameters for cone beam computed tomography were optimized to reduce the radiation dose, in comparison to the initial vendor settings, by referencing IEC 60601-2-44 standards and examining results from neighboring facilities. Conclusions: AGL proved to be effective as a temporary check, but additional commissioning efforts by the user were necessary for a more thorough evaluation and more appropriate initiation, aligning with established clinical practices. |
