Abstract:
1. A method comprising: acquiring a first image of a first radiation field, at least a portion of the first radiation field comprising radiation attenuated by a first device, and the first image including a representation of first scatter radiation generated during acquisition of the first image; acquiring a second image of a second radiation field, at least a portion of the second radiation field comprising radiation attenuated by a second device, and the second image including a representation of second scatter radiation generated during acquisition of the second image; acquiring a third image of a third radiation field, at least a portion of the third radiation field comprising radiation attenuated by a volume, and the third image including a representation of third scatter radiation generated during acquisition of the third image; determining an interpolant comprising a function of radiation attenuation properties and a representation of scatter radiation based on the representation of the second scatter radiation, the representation of the first scatter radiation, radiation attenuation properties of the first device, and radiation attenuation properties of the second device determining a reference scatter image based on the interpolant and on radiation attenuation properties of the volume; modifying the third image based on the reference scatter image to compensate for the third scatter radiation; and, displaying said modified third image.
