Abstract
A method includes reconstructing the projection data based on a reconstruction algorithm that compensates for both motion and tissue density changes of the moving organ across different motion phases, thereby generating motion and density compensated image data. A data compensator includes a reconstructor that reconstructs motion compensated image data based on an reconstruction algorithm that compensates for tissue density changes in a moving object.
Claims25
A method for processing projection data, from an imaging system, of a moving organ, comprising:
- reconstructing the projection data based on a reconstruction algorithm that compensates for both motion and tissue density changes of the moving organ across different motion phases, thereby generating motion and density compensated image data.
A data compensator, comprising:
- a reconstructor that reconstructs motion compensated image data based on a reconstruction algorithm that compensates for tissue density changes in a moving object in projection data.
A computer readable storage medium containing instructions which, when executed by a computer, cause the computer to perform the act of:
- reconstructing projection data and thereby generating image data based on a supplemented motion vector field that compensates for both motion and tissue density changes of a moving organ across different motion phases.
