The UF family of reference hybrid phantoms for computational radiation dosimetry.
Computational human phantoms are computer models used to obtain dose distributions within the human body exposed to internal or external radiation sources. In addition, they are increasingly used to develop detector efficiencies for in vivo whole-body counters. Two classes of computational human phantoms have been widely utilized for dosimetry calculation: stylized and voxel phantoms that descr...
متن کاملPediatric radiation dosimetry for positron-emitting radionuclides using anthropomorphic phantoms.
PURPOSE Positron emission tomography (PET) plays an important role in the diagnosis, staging, treatment, and surveillance of clinically localized diseases. Combined PET/CT imaging exhibits significantly higher sensitivity, specificity, and accuracy than conventional imaging when it comes to detecting malignant tumors in children. However, the radiation dose from positron-emitting radionuclide t...
متن کاملComputational Anthropomorphic Phantoms for Radiation Protection Dosimetry: Evolution and Prospects
Phantoms for radiation dosimetry, including physical phantoms for radiological use in medicine in particular, were introduced as early as the 1910s [1] while those for radiation protection dosimetry started to evolve in the late 1950s. This innovation was driven partly from the consensus that dose quantity for protection purposes should be assessed in “receptor conditions” instead of the tradit...
متن کاملInflammation and infection: imaging properties of 18F-FDG-labeled white blood cells versus 18F-FDG.
UNLABELLED (18)F-FDG and (18)F-FDG-labeled white blood cells ((18)F-FDG-WBCs) are valuable radiopharmaceuticals for imaging focal sites of inflammation and infection. In the present study, the imaging properties of both radiotracers were compared in sterile and septic inflammation models. METHODS Groups of adult male Sprague-Dawley rats (100-120 g) were injected in the left posterior thigh mu...
متن کاملValue of 18F-FDG PET and PET/CT for evaluation of pediatric malignancies.
Successful management of solid tumors in children requires imaging tests for accurate disease detection, characterization, and treatment monitoring. Technologic developments aim toward the creation of integrated imaging approaches that provide a comprehensive diagnosis with a single visit. These integrated diagnostic tests not only are convenient for young patients but also save direct and indi...
