Polymer gels
In polymer gel, monomers such as acrylamid are dispersed in a gelatin
or agarose matrix.
Upon radiation, monomers undergo a polymerization reaction, resulting

in a 3-D polymer gel matrix. This reaction is a function of absorbed
dose.
The dose signal can be evaluated using MR imaging, X-ray computed
tomography (CT), optical tomography, vibrational spectroscopy or
ultrasound.
