Abstract: Systems and methods for determining whether a structure of interest is within a predefined region of interest. An example embodiment of a method includes applying a multiband magnetic resonance imaging sequence in order to simultaneously acquire a first slice of magnetic resonance data from a first slice location and a second slice of magnetic resonance data from a second and different slice location. The first slice is positioned near a first side of the region of interest and the second slice is positioned near a second side of the region of interest. The method further includes determining based on the first and second slice of magnetic resonance data and prior knowledge about at least one of the structure of interest and its surroundings whether the structure of interest is within the region of interest.

Abstract: Disclosed herein is a medical system (100, 300, 500) comprising a processor (104) configured for controlling the medical system and a memory (110) for storing machine executable instructions. Execution of the instructions causes the processor to receive (200) four-dimensional Dixon magnetic resonance image data (122). The four-dimensional Dixon magnetic resonance imaging data is T1 weighted. The four-dimensional Dixon magnetic resonance image data is synchronized to a respiratory signal (124). Execution of the instructions further causes the processor to reconstruct (202) synthetic four-dimensional computed tomographic image data (12) from the four-dimensional Dixon magnetic resonance imaging data. The four-dimensional Dixon magnetic resonance imaging data is synchronized to the respiratory signal.
