  • Reason
    Depending on the type of uniform phantom utilized to perform the pet quality control, the pet calibration factor may be biased due to the system using a specific mu-value of 0.1 cm-1 which is based on the siemens solid germanium-68 phantom. the system will use this default mu-value, regardless of the actual mu-value of the phantom utilized for pet quality control; this may cause a variation in the quantification of the attenuation corrected pet images in order to correct for the variation in mu-values, we recommend that you perform the scanner cross calibration procedure after the 6.7.X software upgrade as well as every time the pet quality phantom is replaced. in addition to cross calibrating the pet scanner to the dose calibrator, this procedure will also account for the mu-value of a liquid or third-party solid germanium-68 quality phantom to ensure more accurate quantification in the pet attenuation corrected images. for complete instructions on the cross calibration procedure, please see your siemens biograph operator’s manual. .
