Homeostasis in concentration of essential elements and its abnormality due to cancer have been observed for single hair samples by X-ray fluorescence analysis using synchrotron radiation. Ca, Br and K are associated with the cellular signal transduction and were found to have two levels of upper...
Recently, the Palamodov algorithm, which was formulated for exact cone-beam reconstruction from data collected along a continuous locus, has been proven to be an excellent approximate algorithm for general cone beam reconstruction. The filtration-backprojection framework of the Palamodov...
X-ray radiographic technique is widely used as Nondestructive Testing (NDT) for inspection of welding joints. The quality of X-ray images is frequently sensitive for noise, lighting and working place surroundings. Therefore, such images need to be carefully examined to identify welding...
In recent years, image reconstruction methods for cone-beam computed tomography (CT) have been widely discussed with default setting of geometry that the normal vector of the detector plane passing the X ray source crosses the rotation axis. However, this may not be true in reality. In this...
Scattering cross sections of radiation interactions with matter form the foundation for diagnostic x-ray imaging, nuclear medicine, and radiotherapy. These cross sections are typically presented as numerical charts in medical physics literature or complicated formulas in quantum electrodynamics...
