Basic physics of X-ray imaging

X-ray imaging physics for nuclear medicine technologists. Part 1: Basic principles of x-ray production.

The purpose is to review in a 4-part series: (i) the basic principles of x-ray production, (ii) x-ray interactions and data capture/conversion, (iii) acquisition/creation of the CT image, and (iv) operational details of a modern multislice CT scanner integrated with a PET scanner. Advances in PET technology have lead to widespread applications in diagnostic imaging and oncologic staging of dise...

X-Ray Physics

We measure a variety of phenomena related to X-Ray absorption and production. We present data which conforms within reasonable error to Moseley’s Law for spectral lines. Our experiment also conforms within experimental error to the approximation that doublet splitting goes as (Z-σ). Bremsstrahlung spectra are presented and analyzed, as are Na electron-positron annhilation lines. The importance ...

X-ray Absorption Spectroscopy

X-ray absorptioń spectroscopy, today widely used as a tool for structural investigations, is described. Theoretically it is shown that above an absorption edge the absorption coefficient is well approximated by a sum of terms, each one describing a particular path followed by the photoelectron outgoing from the atom. Such geometrical feature allows to use X-ray absorption spectroscopy for struc...
