Radiotherapy and Oncology
S728 ESTRO 35 2016 _____________________________________________________________________________________________________ Purpose or Objective: In this work we carried out a series of measurements of a small field to investigate the shape of the dose deposition kernel of a radiotherapy beam. Starting with 2D dose distributions measured with radiochromic films a deconvolution process is followed to obtain the dose deposition kernels. Material and Methods: Radiochromic films Gafchromic EBT2 weredoi:10.1016/s0167-8140(16)32820-1 fatcat:7p6nx35crne6bcfeyabc62ioxe
