Temperature-compensated MOS dosimeter fully integrated in a high-voltage 0.35 µm CMOS process
(Institute of Electrical and Electronics Engineers, 2020-06)
This article presents the design, fabrication, and characterization of an integrated differential dosimeter based on the mismatch of two identical field oxide MOS transistors (FOXFETs). This dosimeter was fabricated in a ...
Effect of inorganic salts and matrix crosslinking on the dose response of polymer gel dosimeters based on acrylamide
(Pergamon-Elsevier Science Ltd, 2018-10)
The use of additives in polymer gel dosimeters to enhance their sensitivity or to improve their performance is of great importance for their application in radiomedicine. Inorganic salts have been used as additives with ...
Feasibility of dose enhancement assessment: Preliminary results by means of Gd-infused polymer gel dosimeter and Monte Carlo study
(Pergamon-Elsevier Science Ltd, 2018-11-11)
This work reports the experimental development of an integral Gd-infused dosimeter suitable for Gd dose enhancement assessment along with Monte Carlo simulations applied to determine the dose enhancement by radioactive and ...
Water-equivalence of gel dosimeters for radiology medical imaging
(Pergamon-Elsevier Science Ltd, 2018-11)
International dosimetry protocols are based on determinations of absorbed dose to water. Ideally, the phantom material should be water equivalent; that is, it should have the same absorption and scatter properties as water. ...
Radiation sensor based on MOSFETs mismatch amplification for radiotherapy applications
(Institute of Electrical and Electronics Engineers, 2016-06)
In this paper we present a new dosimeter based on a pair of thick gate oxide MOSFET sensors. A differential circuit topology with a feedback loop provides stabilized output with selectable sensitivity amplification for ...

Experimental characterization and numerical modeling of total ionizing dose effects on field oxide MOS dosimeters
(Pergamon-Elsevier Science Ltd, 2021-05)
The response of MOS dosimeters fabricated using field oxide as gate insulator was characterized measuring the threshold voltage shift with absorbed dose. Sensitivity for different applied bias and threshold voltage evolution ...
Gel dosimetry measurements and Monte Carlo modeling for external radiotherapy photon beams. Comparison with a treatment planning system dose distribution
(Elsevier Science, 2007-09)
Gel dosimetry has proved to be useful to determine absorbed dose distributions in radiotherapy, as well as to validate treatment plans. Gel dosimetry allows dose imaging and is particularly helpful for non-uniform dose ...
