Continuous moving bed MRI (COMBI) is a high throughput
imaging technique for rapid whole-body examination. A
primary limitation of COMBI is that the frequency and B0
shims are typically optimized for only one body
location. As a result, image quality and parameter
quantification suffers from field variations along the
extent of the body. In this abstract, we present
slice-specific zeroth and first order dynamic B0
shimming in COMBI. Slice-optimized shimming is
demonstrated on a 1.500 meter field of view phantom
setup with significant field homogeneity gains
throughout the full field of view over a static single
station shim.
