[ 1 ] - Detection of Melanoma Skin Cancer by Elastic Scattering Spectra: A Proposed Classification Method
Introduction: There is a strong need for developing clinical technologies and instruments for prompt tissue assessment in a variety of oncological applications as smart methods. Elastic scattering spectroscopy (ESS) is a real-time, noninvasive, point-measurement, optical diagnostic technique for malignancy detection through changes at cellular and subcellular levels, especially important in ear...
[ 2 ] - The Influence of Crystal Size and Material on Intercrystal Scattering and Parallax in PET Block Detectors: A Monte Carlo Study
Introduction: In this study, we utilized the MCNP4C Monte Carlo code to quantitatively evaluate the influence of crystal size and material on intercrystal scatter and parallax effects. Materials and Methods: For each of the 5 selected crystals (BGO, LSO, LYSO, LuAP, GSO), transport of 511 keV photons originating from a point source and incident on the central cry...
[ 3 ] - Simulation of gamma irradiation system for a ballast water treatment
ABSTRACT Background: Invasion by different kinds of ballast water microorganisms is one of the most important marine environment problems around the world therefore preventing the invasion of these unwanted and harmful stowaways is one of the main strategies of responsible agencies. Some of these methods such as ocean excha...
[ 4 ] - A novel approach to automatic position calibration for pixelated crystals in gamma imaging
Introduction: The position estimation in gamma detection system will have constant misplacements which can be corrected in the calibration procedure. In the pixelated crystal uniformly irradiation of detector will produce irregular shape due to position estimation errors. This image is called flood field image and is used to calibrate the position estimation. In this work we pr...
