Abstract: A method for creating a quantitative positron emission tomography (PET) image of a subject or object comprises recording correction information data with an imaging device; transmitting the correction information data to a first evaluating unit which includes at least one of preparing an attenuation map on based on the correction information data and passing on the attenuation map as checking data to a second evaluating unit or sending the correction information data as 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; at least one of initializing correction measures by way of the second evaluating unit or proposing correction measures to a user; and preparing a corrected attenuation map based on the correction measures.

Abstract: A computer-implemented method for determining at least one nuclear medical image data set in nuclear medical imaging using an imaging device includes acquiring nuclear medical raw data sets of a region of interest of a patient in respective acquisition steps during a progression of a tracer in the region of interest; reconstructing at least one nuclear medical image data set from the nuclear medical raw data sets for each acquisition step; determining motion data describing a motion of the patient between acquisition steps from source data describing the motion in the region of interest; and applying motion correction to at least one of the nuclear medical raw data sets or the at least one nuclear medical image data set based on the motion data.
