Abstract: Disclosed herein is a medical system (100, 300, 700) comprising a magnetic resonance imaging system (102) configured to acquire lines of k-space (144) data from a thoracic region (122) of a subject (118). Execution of machine executable instructions (140) causes a computational system (132) to: repeatedly (200) acquire the lines of k-space data by controlling the magnetic resonance imaging system with the pulse sequence commands; repeatedly (202) assemble motion resolved k-space data (146) from the lines of k-space data using at least one cardiac phase and one respiratory phase of the subject as the k-space data is acquired; retrieve (204) at least a portion (148) of the motion resolved k-space data during acquisition of the k-space data; and construct (206) a preliminary three-dimensional cardiac image (150) using at least a portion of the motion resolved k-space data before acquisition of the lines of k-space data is finished. The pulse sequence commands are according to a three-dimensional free running cardiac magnetic resonance imaging protocol.
