Title: Time-of-flight (TOF) positron emission tomography (PET) reconstruction from time-truncated projection data

Abstract: A method of TOF-PET image reconstruction using time-truncated TOF-PET projection data. The time-truncated TOF-PET data is obtained by narrowing the scanner time window to a smaller "time window field of view," which reduces the field of view of a TOF-PET scanner. This results in a lower list mode stream transfer rate, which can be useful in high count rate data acquisitions, in particular .sup.82Rb cardiac studies.
