Utretch 2016
High sensitivity
Water-tissue equivalent
Uniformity in X and Y direction
High spatial resolution
Small sensitive volume (volume effects)
Stability of the response with time (fading)
No variation of the response with accumulated dose
On line reading vs permanent record of dose distribution
