Thermoluminescence fading studies: Implications for long-duration space measurements in Low Earth Orbit

, 2013
Within a 1.5 year comprehensive fading experiment several batches of LiF:Mg,Ti and LiF:Mg,Cu,P thermoluminescence detectors (TLDs) were studied. The TLDs originated from two manufacturers and were processed by three laboratories using different annealing

Improved organ absorbed dose estimation in abdominal CT using DICOM header‐based tube current modulation profiles: Validation with measurements and Monte Carlo simulations

Journal of Applied Clinical Medical Physics, Volume 26, Issue 11, November 2025.
Abstract Purpose Precise determination of organ absorbed doses in computed tomography (CT) is vital for evaluating radiation risk and optimizing radiation dose. This study aimed to improve the accuracy of organ absorbed dose estimates in abdominal CT by integrating tube current modulation (TCM) profiles—extracted from the Digital Imaging and ...

A case study on SSD to SAD linear accelerator calibration transition

Journal of Applied Clinical Medical Physics, Volume 26, Issue 10, October 2025.
Abstract Purpose Modifying calibration conditions of linear accelerators is infrequent and potentially a high‐risk procedure. This study outlines a systematic approach used to transition a linear accelerator's calibration condition in an active clinical environment from source‐to‐surface (SSD) to source‐to‐axis (SAD), while maintaining treatment ...
