Patent number: 11961164Abstract: An improved method for time alignment (TA) procedure and crystal efficiency (CE) normalization estimation procedure for a PET scanner system is disclosed. In the TA procedure modeled time-of-flight (TOF) data are compared against the measured TOF data from an axially short cylinder phantom in order to find individual detector's time offsets (TOs). Then the TOs are estimated simultaneously by matching the TOF center of mass between the modeled and measured TOF data. In the CE estimation, TOF reconstruction of CBM data on the axially short cylinder phantom is performed. Alternating between TOF image reconstruction and CE updates eventually lead to the correct estimation of activity and CE component.Type: GrantFiled: September 29, 2020Date of Patent: April 16, 2024Assignee: Siemens Medical Solutions USA, Inc.Inventors: Vladimir Panin, Mehmet Aykac, Shikui Yan, Brian Kelly
