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.
