Artificial intelligence-assisted thermoluminescence and optically stimulated luminescence dose analysis in radiological protection, medical imaging, nuclear medicine, and radiotherapy
Thermoluminescence (TL) and optically stimulated luminescence (OSL) dosimetry have long been established as reliable techniques for quantifying ionizing radiation dose in radiation protection, medical imaging, radiotherapy, and nuclear medicine. The main value of TL and OSL dosimetry in medical applications lies in their ability to provide accurate, passive, and small-scale radiation measurements. These systems are essential for patient safety (in vivo dosimetry) and regulatory radiation protection for staff. While TL requires heat to release stored energy, OSL uses light stimulation (lasers/light-emitting diodes) and may allow repeated readouts of the same dosimeter, providing a key advantage for data verification. This review examines the emerging role of artificial intelligence (AI) in enhancing dose analysis. It synthesizes current knowledge of luminescent dosimetry principles with recent advances in machine learning and deep learning, highlighting how AI-driven models improve glow-curve and decay-curve processing, reduce uncertainties, and enable high-precision dose estimation across medical applications. The review also explores new trends such as physics-informed neural networks, hybrid TL–OSL data fusion, real-time embedded AI in portable dosimeters, and three-dimensional dose reconstruction using AI-assisted detector arrays. By integrating foundational dosimetry science with state-of-the-art computational methods, the review provides a comprehensive overview of how AI can strengthen accuracy, efficiency, and clinical impact in luminescence-based dosimetry.
