Abstract
A positron emission tomography (PET) scanner system, including a detector that acquires PET event information, the detector being configured to move during acquisition of the PET event information; a first motion unit that acquires first event information of a position of a patient bed, the patient bed being configured to move during acquisition of the PET event information; a second motion unit that acquires second event information of the detector; an event collector that generates an event list of events that includes the PET event information, the first event information, and the second event information; and a list-mode reconstructing unit that reconstructs an image by processing the generated event list.

A positron emission tomography (PET) scanner system, comprising:
- a detector to acquire PET event information, the detector being configured to move during acquisition of the PET event information;
- a first motion unit configured to acquire first event information of a position of a patient bed, the patient bed being configured to move during acquisition of the PET event information;
- a second motion unit configured to acquire second event information of the detector;
- an event collector configured to generate an event list of events that includes the PET event information, the first event information, and the second event information;
- and
- a list-mode reconstructing unit configured to reconstruct an image by processing the generated event list.
A method of reconstructing an image in a positron emission tomography (PET) scanner system that includes a detector and a patient bed, both being configured to move during acquisition of PET information, the method comprising:
- acquiring PET event information;
- acquiring first event information of a patient bed corresponding to the acquired PET event information;
- acquiring second event information of a detector corresponding to the acquired PET event information;
- generating an event list of events that includes the PET event information, the first event information, and the second event information;
- and
- list-mode reconstructing an image by processing the generated event list.
