Claim One:
1. A method of producing a computed tomography (CT) image from a CT scanner imaging in a low-dose CT mode, the method comprising: obtaining, at a processor and from the low-dose CT scanner, an initial low-dose CT image, wherein the low-dose CT image is characterized by a plurality of sub-regions or sub-volumes and a low-dosage noise level; applying, in the processor, the low-dose CT image to a machine-learning model trained using a high-dose CT training image, the high-dose CT training image resulting from a higher radiation dose than that used for the low-dose CT image; and converting, using the trained machine-learning model, the low-dose CT image to an enhanced low-dose CT image exhibiting either or both of a high-dose CT image noise level and a high-dose CT image signal contrast.
