Radiation therapy (RT) is one of the primary modalities for the treatment of cancer with approximately 50% of the cancer patients having some form of RT during their care. RT treatment has advanced considerably in the last decade through the development of improved imaging and radiation modelling to predict dose delivery to individual patients, and of advanced equipment operating dynamically...
Injections of gold nanoparticles (Au-NPs) at the vicinity of low-dose radioactive implants (containing 103Pd or 125I) could enhance the efficiency of prostate cancer brachytherapy. The interaction of low-energy photons with gold produces a large number of photoelectric events that are expected to lead to higher energy deposition. Understanding the impact of intracellular Au-NPs concentration...
Recent findings in populations exposed to radiation indicate dose-related lens opacification occurs at much lower doses (< 2Gy) than indicated in radiation protection guidelines. As a result, research efforts are now being directed towards identifying early predictors of lens degeneration resulting in cataractogenesis. In this study, Raman microspectroscopy was used to investigate the...
Single photon emission tomography (SPECT) is the gold standard and well- established clinical diagnostic imaging technique using designated Tc-99m or I-123 pharmaceuticals for cardiac diseases, bone diseases, and thyroid diseases. The conventional method of producing Tc-99m pharmaceuticals is to use the parent nucleus Mo-99 produced in a nuclear power reactor by a fission reaction of U-235. In...
