Dual-energy imaging of the chest: Optimization of image acquisition techniques for the ‘bone-only’ image

Experiments were conducted to determine optimal acquisition techniques for bone image decompositions for a prototype dual-energy (DE) imaging system. Technique parameters included kVp pair (denoted [ kVp L ∕ kVp H ] ) and dose allocation (the proportion of dose in low- and high-energy projections),...
