Session

Overview: Source strength standardization and dosimetry accuracy are essential for proper brachytherapy dose delivery and clinical trial consistency. This symposium will highlight the latest advances in nuclide dosimetry, clinical calibrations, and brachytherapy treatment planning calculations. The first lecture will feature recent projects in metrology and the ongoing development of a calibration service. The second lecture will review HDR and LDR calibration methods at the clinical level. The timing, resource requirements, tolerance actions, and application of clinical calibrations will be discussed. The final lecture will examine calculations methods that incorporate heterogeneities including model-based systems, artificial intelligence solutions, IMBT, and multiscale dose calculations.
