To perform multi-slice multi-echo abdominal imaging
during free breathing a radial golden angle self-gating
technique was used applying 1D projection navigators in
an automatically added slice. 1D navigators were
utilized to generate a breathing trigger signal through
correlation analysis. Since each time point of the
trigger signal is directly related to a radial readout
in all slices, respiratory phases could be excluded from
image reconstruction for obtaining breathing corrected
images. Image blurring caused by respiratory motion was
highly reduced.
