Glass-Ceramic Scintillators for High-Resolution Medical Imaging

Beckert M.B., Nadler J.H., Kang Z., Wagner B.K., Georgia Tech Research Institute, US

Screens made from micron-sized phosphor particles (such as Gd2O2S:Tb) are efficient and bright X-ray converters used in medical imaging systems. However, the large size of the phosphor particles causes the screen to be opaque and, [...]

Magnetic Properties over Several Length Scales: Micro-magnetic Modeling and Effective Medium Theory

Harter A.W., Mohler G., Moore R., Schultz J., Georgia Tech Research Institute, US

We combine micro-magnetic modeling with effective medium theory to predict the bulk properties of magnetic composites, in particular those of ferrite particles in a non-magnetic matrix. We verify our model using published measured data of [...]
