1. A method for creating a quantitative positron emission tomography (PET) image of a subject or object, the method comprising:
recording correction information data with at least one imaging device, the at least one imaging device including at least one of a magnetic resonance scanner, a computed tomography scanner or a positron emission tomography scanner;
transmitting the correction information data or a first part of the correction information data to a first evaluating unit, the transmitting including at least one of
preparing an attenuation map based on the correction information data by way of the first evaluating unit and sending the attenuation map as checking data to a second evaluating unit, or
sending the correction information data or a second part of the correction information data as the checking data to the second evaluating unit;
assessing the checking data based on a quantity of reference data and detecting possible artifacts in the checking data by way of the second evaluating unit, the assessing including at least one of in the event of the detection of at least one artifact,
initializing correction measures by way of the second evaluating unit, or proposing correction measures to a user by way of the second evaluating unit via an output device and providing a possibility for the user to initialize at least one of the correction measures or correction measures modified by the user, wherein the correction measures are configured to at least one of weaken or eliminate the at least one artifact; and
preparing a corrected attenuation map based on the correction measures,
wherein the corrected attenuation map corresponds to an uncorrected attenuation map if no artifacts have been detected.
