Apparatus, method, computer-readable medium, and system for adjusting data acquisition parameters during a scan performed by a positron emission tomography scanner

摘要

An apparatus, method, computer-readable medium, and system for adjusting data acquisition parameters during a scan performed by a Positron Emission Tomography (PET) scanner. The method includes obtaining, during the scan, a current temperature of a detector of the PET scanner, and adjusting, based on the current temperature, the data acquisition parameters used by the PET scanner during the scan.

1. An apparatus for adjusting data acquisition parameters during Positron Emission Tomography (PET) event data acquisition, comprising:
a PET scanner configured to perform the PET event data acquisition; and a controller configured to
obtain, during the PET event data acquisition, a current temperature of a detector of the PET scanner,adjust, based on the current temperature, location of an energy window used by the PET scanner during the PET event data acquisition,acquire PET event data using the energy window adjusted based on the current temperature, andgenerate a PET image based on the PET event data acquired.
