Getting measurements, of whıch are necessary for three diamensional treatment planning system, from the photon beams with different energies that are obtained from linear accelerator treatment machine

In this study, using the Electa Synergy Linear Accelerator located at Dr. Abdurahman Yurtarslan Ankara Oncology Education and Research Hospital, dd % value, dose profiles, fanline and dose out put measurement tests in open field and wedge field were measured in water phantom, air and solid phantoms using 6 MV and 18 MV photon beams. Fanline, dd % value and dose profiles in water phantom , dose out put in dmax were measured in solid phantom and air. The value, necessary for Precise Plan Treatment Planning Systems were measured. Photon treatment was planed, after the obtained results were transfered Precise Plan treatment planning system. Dose values obtained from referans conditions which calculated by theoretical and treatment planning system were compared with dosimetric values.
