DETECTORS FOR MEASUREMENT-2D/3D detectors
Advantages
A number of polymer gel formulations are
commercially available
.
There is a
semi-linear
relationship between the NMR relaxation rate
and the absorbed dose at a point in the gel dosimeter.
Due to the large proportion of water, polymer gels are nearly
water
equivalent
and no energy corrections are required for photon and

electron beams used in radiotherapy.
Polymer gels are well suited for use in
high dose gradient regions
,
(e.g., stereotactic radiosurgery).
