To acquire dynamic movements of the whole knee with
isotropic resolution a 3D radial center-out acquisition
scheme is combined with a low cost experimental
measurement setup to perform single passive knee
flexion. With a spatial resolution of (1.251.251.25)
mm, the acquired 4D dynamic data sets are well suited
for highly flexible subsequent image analysis including
reconstruction of arbitrarily oriented or curved slices.
In this work, we describe the measurement setup and
imaging sequence and show the first basic measurement
and reconstruction results.
