1. A computed tomography (CT) medical imaging system comprising:
an x-ray source configured to deliver x-rays to an object as the x-ray source is rotated about the object;
a processor configured to:
control the x-ray source to deliver x-rays to the object;
perform an image acquisition process using a first, high-energy detection threshold to generate a narrow-spectrum, high-energy, first dataset and at least one second, low-energy detection threshold to generate at least one wide-spectrum, low-energy second dataset; and
create an image of the object from the second dataset that has been processed using the first dataset to reduce scatter artifacts compared to an image reconstructed from the second dataset without using the first dataset.
