Image quality in forensic CT imaging

, 2018
What factors affect the diagnostic image quality in forensic computed tomography (CT) imaging? In this thesis I briefly present the main steps from CT scanning to diagnostics. The thesis is built on four core papers. The first paper focuses on reconstructions of a quality control phantom measurement series. Objective image quality descriptors (contrast

Investigation of Micro‐Nutrient Elemental Distribution in a Black Wheat (Triticum aestivum L.) Grain Using Synchrotron Assisted Microprobe X‐Ray Fluorescence Analysis at Indus‐2

X-Ray Spectrometry, EarlyView.
ABSTRACT Spatial localization of various essential dietary elements present in a black wheat (Triticum aestivum L.) grain has been investigated using synchrotron assisted micro X‐ray fluorescence measurements at BL‐16 beamline of Indus‐2 synchrotron facility. The results showed that most of the important dietary minerals like calcium (Ca), potassium (K)

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF

X-Ray Spectrometry, EarlyView.
ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.

Spectromicroscopy Analysis of Chicken Egg Shells

X-Ray Spectrometry, EarlyView.
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

Integrated X‐Ray, Gamma Radiation, and Micro‐CT Techniques for Quantitative Wood Characterization

X-Ray Spectrometry, EarlyView.
ABSTRACT The present research integrates microcomputed tomography (micro‐CT), x‐ray fluorescence, and gamma‐ray transmission to quantitatively characterize wood species. A total of 22 samples from seven species were analyzed for density (ρ), linear attenuation coefficient (μ), Compton scattering, micro‐CT gray values (GV), porosity, mass attenuation ...
