Popis: Introduction: Radiotherapy still the most facilitated modality for treatment malignant brain tumors with or without chemotherapy and after surgery or when surgery is impossible. Purpose: Comparison between the effects of three planning techniques with similar, opposed and non-wedges in brain tumor cases. Methods: Twenty patients with brain tumors (Glioblastoma Multiform) of both sexes were enrolled in the study. A LINAC with 6MV photon beam was used to deliver the prescribed dose. The whole brain technique was applied to each patient and the planning was constructed with non-wedges, similar wedges and opposed wedges within 95% to 107% of the prescribed dose as recommended by the RTOG. The considered organs at risk were; Right and Left (eyes, lenses, and optic nerves), optic chiasma and the brain- stem. Results: The results showed significant difference (at the level P
