The comparison between QUASAR/A16 ion chamber measurements and Eclipse calculations. The measurements points are separated in two categories. Points 1 and 2 were located in high‐dose area ( $dose > 80 %$ of prescribed dose), while the other points (3 to 6) were located in lower dose area ( $dose < 80 %$ of prescribed dose).
