Gel Dosimetry (1st Edition)

Advances in radiotherapy technology during the last 25 years have significantly improved both dose conformation to tumors and the preservation of healthy tissues, achieving almost realtime feedback by means of high-precision treatments and theranostics. Owing to this, developing high-performance systems capable of coping with the challenging requirements of modern ionizing radiation is a key issue to overcome the limitations of 1D and 2D conventional dosimeters. In this context, “Gel dosimetry” is the most promising tool for the evaluation of 3D high-spatial-resolution dose distributions, and the studies about these materials represent the starting point for developing performance and innovative systems. Gel dosimeters are based on chemical dosimeters in which radiation-induced chemical reactions occur. The addition of gelling agents can enable these chemical reactions to be stabilized spatially, which enables the 3D dose distribution within the volume of the dosimeter to be determined. Despite extensive research over the last three decades, gel dosimeters have yet to achieve widespread clinical acceptance, mainly because of three major practical concerns; toxicity of active materials, oxygen sensitivity of the dose response, and spatial instability of dose information. A number of gel dosimetry systems have been developed over the years with differing mechanisms of operation and varying degrees of success in alleviating the practical issues inhibiting clinical application.

Whereby, this Special Issue invites all researchers and clinicians to publish original research articles, rapid communications, or reviews concerning basic, translational, and clinical research about ionizing radiation dosimetry. Suitable topics include, but are not limited to optimization of dosimetric hydrogel matrices and investigation of physical–chemical mechanisms involved in the dosimetric response.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Gels is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2100 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
