Introduction: This study quantifies the dosimetric impact of lateral and longitudinal positioning errors on left-sided breast cancer during 3D conformal radiation therapy, employing both mono isocenter (MIT) and double isocenter technique (DIT) irradiations, and explores the frequency dependence of these errors. Material and Methods: The study includes 10 left breast cancer patients, with two reference treatment plans created for each using both MIT and DIT techniques. Positioning errors of 2mm and 4mm in the right and inferior directions were simulated across varying error repetition scenarios (1 time, 5 times, 10 times, and 25 times) throughout the 25-fraction treatment period. Statistical analysis employed paired samples Student t-tests with a significance level of α |
