Dosimetric evaluation of the tangential and supraclavicular breast radiotherapy fields junction in mono and dual isocentric techniques with practical measurement and comparison versus TomoDirect technique

Key Points

• To evaluate the dosimetric performance of tangential and supraclavicular fields in breast radiotherapy using different techniques.
• Used Monaco Treatment Planning System (TPS) with XVMC and CCC algorithms
• Compared dose distributions from mono and dual isocentric techniques to TomoDirect
• Conducted practical measurements of dose homogeneity and surface dose.
• TomoDirect technique demonstrated optimal dose homogeneity at junctions.
• MI technique provided better tumor dose coverage with lower surface doses in the supraclavicular area.
