Method and apparatus to detect and correct motion in list-mode PET data with a gated signal
A PET scanner generates a plurality of time stamped lines of response (LORs). A motion detector detects a motion state, such as motion phase or motion amplitude, of the subject during acquisition of each of the LORs. A sorting module sorts the LORs by motion state and a reconstruction processor reco...

| Summary: | A PET scanner generates a plurality of time stamped lines of response (LORs). A motion detector detects a motion state, such as motion phase or motion amplitude, of the subject during acquisition of each of the LORs. A sorting module sorts the LORs by motion state and a reconstruction processor reconstructs the LORs into high spatial, low temporal resolution images in the corresponding motion states. A motion estimator module determines a motion transform which transforms the LORs into a common motion state. A reconstruction module reconstructs the motion corrected LORs into a static image or dynamic images, a series of high temporal resolution, high spatial resolution images. |
