Apparatus and method for reconstructing an image with reduced motion artifacts

A computer readable storage medium having a computer program stored thereon and representing a set of instructions that when executed by a computer causes the computer to:

• acquire mechanical motion data acquired from an imaging volume;
• determine a position of a selected sub-volume in the imaging volume as a function of time from the mechanical motion data;
• determine a temporal window specific to the selected sub-volume for image reconstruction of the selected sub-volume, the temporal window corresponding with a minimum amount of mechanical motion of the selected sub-volume;
• and
• reconstruct an image of the selected sub-volume from imaging data acquired from the object in motion during the temporal window.

A method for reconstructing an image substantially free of motion artifacts comprising:

• calculating a mapping function that provides a location of each sub-volume of an imaging volume as a function of time from ultrasound data;
• determining a respective acquisition window for each sub-volume of the imaging volume from the mapping function;
• and
• reconstructing an image of the imaging volume substantially free of motion artifacts from imaging data acquired from the imaging volume.
