Mathematical models for kinetics of radiopharmaceuticals in humans were developed and are used to estimate the radiation absorbed dose for patients in nuclear medicine by the International Commission on Radiological Protection and the Medical Internal Radiation Dose (MIRD) Committee. However, due to the fact that the residence times used were derived from different subjects, partially even with...

Abstract Purpose In this work, we address image segmentation in the scope of dosimetry using deep learning and make three main contributions: (a) to extend optimize architecture an existing convolutional neural network (CNN) order obtain a fast, robust accurate computed tomography (CT)-based organ method for kidneys livers; (b) train CNN with inhomogeneous set CT scans validate daily dosimetry;...

Abstract Introduction We have suggested that mean Opening Pressure (Op) recorded during Anal Acoustic Reflectometry (AAR) predominantly represents IAS function however, the extent remains unknown. The aim was to investigate this by excluding external anal sphincter general anaesthetic (GA) with confirmed neuromuscular blockade (NMB). Method Patients undergoing elective abdominal surgery requiri...

Background: The accident at the Fukushima Daiichi nuclear power plant increased level of anxiety related to radioactive contamination various foods sourced in Japan. Particularly, after accident, detection artificial radionuclides locally produced raised food safety concerns. In this study, radioactivity concentrations and annual ingestions <sup>40</sup>K <sup>137</sup>C...

Introduction: There are many ways to treat cancer and pain relief. One of the methods is radiopharmaceutical therapy. Indium 111-rituximab contains the radioisotope indium-111 and rituximab. The Indium-111, after decay, emits gamma rays with energies of 245 KeV and 171 KeV, and beta-radiation of 26 KeV. In this study, the absorbed dose of 111In-Rituximab in human body was calcu...
