Note: Spatial resolution of Fuji BAS-TR and BAS-SR imaging plates

Abstract

The spatial resolution of two types of imaging plates, Fuji BAS-TR and Fuji BAS-SR, has been measured using a knife-edge x-ray source of 8-keV Cu K α radiation. The values for the spatial resolution, defined as the distance between 10 and 90 levels of the edge spread function, are 94 μm and 109 μm, respectively. The resolution values are important for quantitative analysis of x-ray and particle imaging and spectroscopic diagnostics. © 2012 American Institute of Physics.
