A geometric solution (GS) to balanced steady state free
precession (bSSFP) signal modulation in MRI has recently
shown to additionally mitigate motion artifacts. The
underlying mechanism behind its correction of noise-like
artifacts is explored through simulations that permit
evaluation of the GS solution performance as a function
of the base image noise radiality relative to the
spokes used for GS localization. It is discovered that
the GS is resilient to any such radially-oriented noise,
indicating GS-bSSFP applications in clinical scenarios
that may suffer from noise-like artifacts such as those
caused by patient motion, flow, and RF interference.
