Dose distribution of narrow beam irradiation for small lung tumor.


PURPOSE To aid in the selection of incident X-ray energy for stereotactic irradiation (STI) of lung tumor, dose distribution was investigated in a model of a thorax embedded with a tumor. METHODS AND MATERIALS The dose distribution in a thorax model was calculated using the EGS4 Monte Carlo simulation; it was also measured with dosimetric film of a… (More)
