Radioluminescence 3D dose reconstruction for FLASH and conventional radiotherapy [PDF]

open access: yesScientific Reports
FLASH radiotherapy requires dosimetric techniques capable of operating at ultra-high dose rates (UHDR), where conventional detectors often suffer from saturation, limited temporal resolution or lack of spatial information. Radioluminescence imaging (RLI)

Improved X-ray absorption capability of Core-shell nano-transducer in situ enhances γ-ray-excited radioluminescence imaging in vivo [PDF]

open access: yesJournal of Nanobiotechnology
Background Radioluminescence imaging (RLI) using nanoscintillators offers great potential for biomedical applications, yet remains constrained by low quantum efficiency and the reliance of Cerenkov imaging on high-energy radionuclides.

Application and Development of Noncontact Detection Method of α-Particles Based on Radioluminescence

open access: yesSensors, 2021
The detection of α particles is of great significance in military and civil nuclear facility management. At present, the contact method is mainly used to detect α particles, but its shortcomings limit the broad application of this method. In recent years,

Monitoring of Ultra-High Dose Rate Pulsed X-ray Facilities with Radioluminescent Nitrogen-Doped Optical Fiber

open access: yesSensors, 2022
We exploited the potential of radiation-induced emissions (RIEs) in the visible domain of a nitrogen-doped, silica-based, multimode optical fiber to monitor the very high dose rates associated with experiments at different pulsed X-ray facilities.

Optical Fiber-Based Monitoring of X-ray Pulse Series from a Linear Accelerator

open access: yesRadiation, 2021
We investigated in this work the radioluminescence properties of a Ce-doped multimode silica-based optical fiber (core diameter of 50 µm) manufactured by the sol–gel technique when exposed to the high-energy X-rays (~600 keV) of the ORIATRON facility of ...

In silico optimization of radioluminescence microscopy [PDF]

open access: yesJournal of Biophotonics, 2017
Radioluminescence microscopy (RLM) is a high‐resolution method for imaging radionuclide uptake in live cells within a fluorescence microscopy environment. Although RLM currently provides sufficient spatial resolution and sensitivity for cell imaging, it has not been systematically optimized.
