After some theoretical remarks on multienergy radiology, a simulation program able to perform the following tasks is described: Image production and acquisition, image processing and test pattern simulation. Using a test pattern based on geometric structures with schematic shape of a thorax, dual and triple energy are investigated. Pictures showing material look-alike and removal, in presence of various noise sources (photon noise, detector electronic noise, quantization noise) are presented. Simulation program provides useful indications which will be employed in the experimental stage we are starting in our laboratory. Finally some considerations on multienergy digital radiology are discussed. © 1985 SPIE.

Abstract
After some theoretical remarks on multienergy radiology, a simulation program able to perform the following tasks is described: Image production and acquisition, image processing and test pattern simulation. Using a test pattern based on geometric structures with schematic shape of a thorax, dual and triple energy are investigated. Pictures showing material look-alike and removal, in presence of various noise sources (photon noise, detector electronic noise, quantization noise) are presented. Simulation program provides useful indications which will be employed in the experimental stage we are starting in our laboratory. Finally some considerations on multienergy digital radiology are discussed. © 1985 SPIE.
