Telah dilakukan distribusi dosis radiasi dari penggabungan lapangan foton dan lapangan elektron berdasarkan grafik Dose Volume Histogram (DVH) pada terapi kanker payudara. Penelitian bertujuan untuk mengetahui pengaruh jarak antara lapangan foton dan lapangan elektron terhadap distribusi dosis radiasi. Pengambilan data dilakukan dengan memvariasikan Source Surface Distance (SSD) dan jarak antara lapangan foton dan elektron. SSD yang digunakan yaitu 97,5 cm; 100 cm dan 102,5 cm dengan variasi jarak untuk setiap SSD mulai dari 0 cm; 0,3 cm; 0,6 cm dan 1 cm. Analisis data dilakukan pada hasil grafik DVH yang didapatkan dari Treatment Planning System (TPS). Distribusi dosis radiasi yang diperoleh tidak menunjukkan pengaruh dari jarak antar lapangan foton dan elektron. Nilai dosis maksimum yang diperoleh melebihi standar dosis maksimum yang ditetapkan oleh ICRU Report 62.References
