The patient-centered approach to imaging is an increasing focus in Radiology departments. For patients undergoing CT, this includes a personalized examination, one that provides diagnostic image quality while managing radiation dose (As Low As Reasonably Achievable, or ALARA). The Philips iPatient approach to patientcentered imaging includes new, patientspecific methods to facilitate optimal ma...

clinical application of embryonic stem (es) cells faces difficulties regarding tissue rejection as well as ethical limitations. one solution for these issues is to reprogram somatic cells by the injection of their nucleus into an enucleated oocyte or zygote. however, technical complications and ethical considerations have impeded the therapeutic implications of this technology. an approach whic...
Introduction: The determination of accurate dose distribution is an issue of fundamental importance in radiotherapy, especially with regard to the fact that the human body is a heterogeneous medium. Therefore, the present study aimed to analyze the density and isodose depth profiles of 6 MV beam in a SP34 slab-wooden dust (pine)-SP34 slab (SWS) heterogeneous phantom. Materials and Methods: Th...
Background: Reliable estimation of radiation-absorbed dose is necessary to evaluate the benefits and the risks of radiopharmaceuticals used for diagnostic or therapeutic purposes in nuclear medicine. Materiel and Methods: This study included 47 patients treated with iodine-131 for Graves’ disease. A comparative study between Geant4 Monte Carlo simulation and MIRD formalism was carried out to ev...
