Classification: CPC A  G | IPC A  G

Claim 12:
13. An apparatus for computed tomography (CT) metal artifact reduction (MAR), the apparatus comprising:
a projection completion circuitry configured to generate an intermediate CT image data based, at least in part, on input CT projection data, the intermediate CT image data configured to include fewer artifacts than an uncorrected CT image reconstructed from the input CT projection data;
a detail image circuitry configured to generate detail CT image data based, at least in part, on input CT image data; and
an artificial neural network (ANN) configured to generate CT output image data configured to include fewer artifacts compared to the intermediate CT image data, the ANN comprising at least two parallel CT image data streams and a CT output image data stream, a first of the at least two parallel CT image data streams is based, at least in part, on the intermediate CT image data, a second of the at least two parallel CT image data stream is based, at least in part, on the detail CT image data, the CT output image data stream is based, at least in part, on respective outputs of the at least two parallel CT image data streams that are combined to form an input of the CT output image data stream.
