Computer-implemented method for determining nuclear medical image data sets in dynamic nuclear medical imaging, determining device and electronically readable storage medium

A determining device for determining nuclear medical image data sets in dynamic nuclear medical imaging, comprising:

• a first interface configured to provide nuclear medical raw data sets of a field of view acquired over a time interval, wherein the time interval comprises a progression period of a tracer in the field of view and each nuclear medical raw data set is acquired in one of multiple time frames of the time interval;
• a second interface configured to provide an anatomical image showing an anatomy in the field of view;
• a selection unit configured to select at least one of the nuclear medical raw data sets as a basis raw data set;
• a reconstruction unit configured to reconstruct a first nuclear medical image data set by
• iterative reconstruction of the basis raw data set based on the anatomical image to incorporate anatomical information, or
• using a first trained function applying the iterative reconstruction to the anatomical image and at least one of the basis raw data set or a preliminary reconstructed data set of the basis raw data set;
• a determination unit configured to use a second trained function to determine at least one further nuclear medical image data set for,
• at least one other frame if the basis raw data set is taken from one single frame, wherein input data of the second trained function includes,
• at least one of the nuclear medical raw data set of the respective frame or a preliminary reconstructed image reconstructed therefrom, and
• an already determined nuclear medical image data set;
• and
• a third interface configured to output at least the at least one further nuclear medical image data set.
