Abstract: The article presents a study on machinery testing of high dose rate (HDR) source assembly for brachytherapy through a non-destructive process, three-dimensional (3D) X-ray micro-tomography. It states that the study aims to standardise the welding parameters for the development of the HRD source assembly. It also proves the effectiveness of 3D X-ray micro-tomography for detecting micro-welds defects in HDR source assemblies.
