In this work we propose
a simple method for increasing the spatio-temporal incoherence of a golden
angle radial time-series acquisition by mildly perturbing the golden angles
with a random variable. Despite its quasi-random distribution of golden angle
samples, x-f point spread function analysis reveals strong coherence along the
frequency domain. When the golden angles are slightly jittered using a normal
random variable with small variance, the x-f point spread functions take on a
more diffuse, noise-like appearance, making the acquisition scheme more
appropriate for k-t reconstruction methods relying on incoherence, while
maintaining its favourable spatial properties.
