Methods and apparatus for image reconstruction

A computed tomographic (CT) imaging system for reconstructing an image of an object, said imaging system comprising:

• a detector array;
• at least one radiation source;
• and
• a computer coupled to said detector array and said radiation source, said computer configured to:
• generate a first partial image using projection data acquired at a first imaging position in a step-and-shoot imaging mode;
• generate a second partial image using projection data acquired at a second imaging position;
• and
• combine the partial images to form a final image.

A computer readable medium encoded with a program code segment executable by a computer for reconstructing an image of an object, said segment programmed to instruct the computer to:

• generate a first partial image using projection data acquired at a first imaging position in a step-and-shoot imaging mode;
• generate a second partial image using projection data acquired at a second imaging position;
• and
• combine the partial images to form a final image.
