Abstract
A method for correcting motion artifacts within a volumetric data set is provided. The method includes obtaining a volumetric data set containing spatial and temporal information regarding an object. The volumetric data set is organized into data slices such that at least two adjacent data slices are representative of a common physical slice within the object at different points in time. The relative motion between adjacent data slices in determined for the slices of the volumetric data set and used to correct for the relative motion between said adjacent slices.
Claims22
A method for correcting motion artifacts within a volumetric data set, comprising:
- obtaining a volumetric data set containing spatial and temporal information regarding an object, said volumetric data set being organized into data slices, at least two adjacent said data slices being representative of a common object at different points in time;
- determine relative motion between adjacent first and second data slices in said volumetric data set;
- correcting said relative motion between said adjacent first and second slices;
- and
- determining a cumulative motion of said first and second data slices with respect to a reference coordinate system of said volumetric data set.
A system for correcting motion artifacts within a volumetric data set, comprising:
- memory storing a volumetric data set containing spatial and temporal information regarding an object, said volumetric data set being organized into data slices, at least two adjacent said data slices being representative of a common object at different points in time;
- and
- a processing unit determine relative motion between adjacent first and second data slices in said volumetric data set, said processing unit, correcting said relative motion between said adjacent first and second slices, wherein said processing unit determines a cumulative motion of said first and second data slices with respect to a reference coordinate system of said volumetric data set.
