Abstract: Timing calibration of a positron emission tomography (PET) imaging device (2) uses a radioactive source (20) comprising a positron-emitting radioisotope having a decay path including emission of two oppositely directed 511 keV gamma rays and a cascade gamma ray at a cascade gamma ray energy. A timestamped radiation detection event data set acquired from the radioactive source by the PET imaging device is processed using energy window filtering (32) and time window filtering (36) to generate a coincidence data set (40, 42, 44) including event pairs (40) each consisting of two coincident 511 keV events and cascade event pairs (42) or triplets (44) each consisting of at least one coincident 511 keV event and a coincident cascade event at the cascade gamma ray energy. A timing calibration (12) is generated using the coincidence data set. The timing calibration comprises offset times for PET detectors of the PET imaging device.

Abstract: A method and system facilitate scheduling of a response to a text directed to a landline by maintaining a registration of a handler system with a text hub, wherein the text hub intercepts text messages forwarded through a mobile carrier to multiple dedicated landlines. A message router of the registered handler system identifies the destination landline and routes the text message to a call center server system based on the identified destination landline. The method additionally includes processing the text message at the call center server utilizing a text processor. The text processor identifies a text sender, schedules a follow-up communication at a follow-up time, and queues the text message and scheduled follow-up.
