Introduction: Due to the prevalence of skin problems in patients after radiotherapy, skin dose measuring is importance. Content: Skin in vivo dosimetry means measuring the patient's (or phantom) skin dose during radiotherapy. According to the ICRP 59, the dose at the depth of 0.07 mm is known as a skin dose. The most radiosensitive epidermis cells are located...

BACKGROUND Targeted radionuclide therapy is a rapidly growing modality. A few commercial treatment planning systems are entering the market. However, some in-house systems are currently developed for a more flexible and customized dosimetry calculation at voxel-level. For this purpose, we developed a novel software, VoxelMed, and performed a comparison with the software STRATOS. METHODS The v...

background: in nuclear medicine application often it is required to use computational methods for evaluation of organ absorbed dose. monte carlo simulation and phantoms have been used in many works before. the shape, size and volume in organs are varied, and this variation will produce error in dose calculation if no correction is applied. materials and methods: a computational framework for co...

PURPOSE The purpose of this study is the development of reference pediatric phantoms for 5- and 10-year-old children to be used for the calculation of organ and tissue equivalent doses in radiation protection. METHODS The study proposes a method for developing anatomically highly sophisticated pediatric phantoms without using medical images. The 5- and 10-year-old male and female phantoms pre...

PURPOSE This investigation studies the feasibility of PRESAGE, a 3D polyurethane dosimeter, for relative dosimetry measurements of clinically relevant proton treatments using an anthropomorphic head phantom developed by the Radiological Physics Center (RPC). Performance of a low-LET dependent PRESAGE was evaluated by comparison to the traditionally used radiochromic film, EBT2, and thermolumine...
