Continuous moving bed MRI (COMBI) is a high throughput
imaging technique for rapid whole body examination. In
this abstract, golden angle increment (111.25o azimuthal
step) based radial COMBI is introduced and compared to
previously reported linear angle COMBI. The benefit of
Golden angle sampling over a linear sampling scheme in
retrospective profile binning for arbitrary slice
thickness reconstruction is highlighted. We reconstruct
gradient echo images acquired with GA sampling with 8,
10 (undersampled) and 13.4 mm (fully sampled) slice
thickness and compare image quality with fully sampled,
13.4 mm linear angle radial reconstruction.
