“…At room temperature, the lifetime is 27 μs, with fading less than 1% in 6 months. The stabilization time required for detector readability is 30 min The signal depletion is decreased by 0.7% per reading (Madden et al 2021). Furthermore, the effective point of measurement for the OSLDs was situated at the center of the detector, at a depth of 1 mm from the detector surface, corresponding to a waterequivalent depth of 1.25 mm.…”

Purpose: To address the shortcomings of current procedures for evaluating the measured-to-planned dose agreement in in-vivo dosimetry (IVD), this study aimed to develop an accurate and efficient novel framework to identify the detector location placed on a patient's skin surface using a 3D camera and determine the planned dose at the same anatomical position corresponding to the detector location. Methods: Breast cancer treatment was simulated using an anthropomorphic adult female phantom (ATOM 702-D; CIRS, Norfolk, VA, USA). An optically stimulated luminescent dosimeter was used for surface dose measurements (MyOSLchip, RadPro International GmbH, Germany) at six IVD points. Three-dimensional surface imaging (3DSI) of the phantom with the detector was performed in the treatment position using a 3D camera. The developed framework, iSMART, was designed to import 3DSI and treatment planning data for determining the position of the IVD detectors in the 3D treatment planning DICOM image. The clinical usefulness of iSMART was evaluated in terms of accuracy and efficiency, for comparison with the results obtained using cone-beam computed tomography (CBCT) image guidance. Results: The relative dose difference between the planned doses determined using iSMART and CBCT images displayed similar accuracies (within approximately ±2.0%) at all detector locations. The relative dose differences between the planned and measured doses at the six detector locations ranged from –4.8% to 3.1% for the CBCT images and –3.5% to 2.1% for iSMART. The total time required to read the planned doses at six detector locations averaged at 8.1 and 0.8 min for the CBCT images and iSMART, respectively. Conclusions: The proposed framework can improve the robustness of IVD analyses and aid in accurate and efficient evaluations of the measured-to-planned dose agreement.

“…It is also nearly tissue-equivalent. Nevertheless, its potential use in routine dosimetry is somewhat limited due to high toxicity of this material, especially in the powder form [13][14][15].…”

Optically stimulated luminescence (OSL) and thermoluminescence (TL) methods are commonly used in dosimetry of ionizing radiation and dating of archaeological and geological objects. A typical disadvantage of OSL detectors is signal loss over a longer time scale. In this article, we present a method of studying this phenomenon as well as monitoring the state of the detector by means of optical sampling. The method was used to determine the OSL signal loss (fading) characteristics of selected potassium feldspars.
