In radiation therapy, an accurate dose measurement and a precise dose delivery to the tumor are directly associated with better treatment outcomes in terms of higher tumor control and lower post radiation therapy complications. Recently, gel dosimetry was developed into a powerful tool for radiotherapy treatment verification and quality assurance. This review summarizes development of gel dosimeter models through improvement in their sensitivity and uniformity as three- dimensional detectors. The most important characteristics as well as the limitations that can affect the performance of the gel dosimetry systems have been explained. An outline of both clinical and research contemporary applications is given particularly emphasizing new applications like brachytherapy, diagnostic radiology and radiobiological experiments. Review concludes through an overview of future directions in development of this important dosimetric tool revolving.
