چکیده

tumour volume and clinical target volume among various radiation oncologists, which can potentially lead to variation in tumor control or adverse effects. Interobserver variation can reduce with experience or by utilizing additional facilities such as CT–MRI fusion or CT–PET fusion. Several publications have reported that MRI and PET scans [Figures 1 and 2] can significantly change the tumor volume (GTV), which was delineated on the CT scan alone. These additional modalities also help in reducing the interobserver variations.

Dose Distribution Analysis of Rapid Arc and Intensity Modulated Radiotherapy Plan in Head and Neck Cancer

Introduction: Globally, intensity-modulated radiation therapy (IMRT) is considered as highly precise and accurate method of radiotherapy planning. This technique amplifies spatial dose distribution conformity by modulating the intensity of radiation beams in each sub-volume. Additionally, it can reduces the dose to surrounding critical organs and deliver the planned dose to targets with the nom...
