Multi-phase magnetic resonance image reconstruction method for heart cycle

The method involves providing a nuclear magnetic resonance image of a required heart phase by providing a signal indicating the successive cycles of the heart. The associated image data are determined for each successive cycle, whereby each data set is associated with a time mark, if it lies in one...

Beschreibung
Zusammenfassung:	The method involves providing a nuclear magnetic resonance image of a required heart phase by providing a signal indicating the successive cycles of the heart. The associated image data are determined for each successive cycle, whereby each data set is associated with a time mark, if it lies in one half of the hear cycle. A data array is formed from the data, from which an image can be reconstructed for the required heart phase. The selected heart phase is correlated with a required point of a systolic or diastolic period of the heart cycle, for selection of data correlated with the required point. The image is reconstructed from the data array obtained from the selected data.
