Classification: CPC G | IPC G

Claim 17:
18. An image processing system comprising:
a display device;
a user input device;
a trained multi-dimensional statistical regression model;
a processor communicably coupled to the display device, the user input device, and a non-transitory memory storing the trained multidimensional statistical regression model and including instructions that when executed cause the processor to:
in a first step, reconstruct a first computed tomography (CT) image of a region of interest (ROI) of a subject from high helical pitch projection data, using interpolated data to fill in missing projection data of the high helical pitch projection data;
in a second step, generate a second CT image using the trained multidimensional statistical regression model, the second CT image of higher quality than the first CT image;
in a third step, iteratively correct the second CT image based on the first CT image; and
display the second CT image via the display device; and wherein the trained multidimensional statistical regression model has a neural network architecture.
