title: One-shot dual-energy subtraction imaging.
abstract: Dual-energy subtraction imaging by a single x-ray exposure (one shot) can easily be performed by using computed radiography with scanning laser-stimulated luminescence. In a phantom study, a thin copper filter placed between two imaging plates produced a dual-energy subtracted image from a single x-ray exposure. One-shot dual-energy subtraction imaging was also useful in the diagnosis of thoracic lesions.
