Abstract

The contrast sensitivity and patient entrance dose of a prototype computed radiography (CR) system is examined, and the results compared with those obtained from computed tomography and conventional radiography. Limiting perceptibility measurements of hole patterns are used to generate contrast-detail-dose diagrams for various contrasts, hole diameters, doses and scatter thicknesses. A perceptibility-dose factor is defined from which the relative dose efficiencies are derived for CR and conventional radiography.
