Abstract

Computer-implemented method for determining nuclear medical image data sets (39, 40) in dynamic nuclear medical imaging, comprising:- providing nuclear medical raw data sets (36) 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 (36) is acquired in one of multiple time frames, into which the time interval is divided,- providing an anatomical image (35) showing the anatomy in the field of view,- selecting as least one of the nuclear medical raw data sets (36) as a basis raw data set (38),- reconstructing a first nuclear medical image data set (39) by either* iterative reconstruction of the basis raw data set (38) using a prior based on the anatomical image (35) to incorporate anatomical information,or* using a first trained function applying such an iterative reconstruction to the anatomical image (35), and the basis raw data set (38) and/or a preliminary reconstructed data set (37, 41) thereof,- using a second trained function (33) to determine at least one further nuclear medical image data set (40) for,* if the basis raw data set (38) is taken from one single frame, at least one other frame, in particular all other frames,* else, at least one frame, in particular all frames, as output data, wherein input data of the second trained function (33) comprises* the nuclear medical raw data set (36) of the respective frame and/or a preliminary reconstructed image (37, 41) reconstructed therefrom, and* an already determined nuclear medical image data set (39, 40)
