Resumen:
Automatic scan planning for magnetic resonance
imaging of the knee aims at defining an oriented bounding
box around the knee joint from sparse scout images in order
to choose the optimal field of view for the diagnostic images
and limit acquisition time. We propose a fast and fully
automatic method to perform this task based on the standard
clinical scout imaging protocol. The method is based on
sequential Chamfer matching of 2D scout feature images
with a three-dimensional mean model of femur and tibia.
Subsequently, the joint plane separating femur and tibia,
which contains both menisci, can be automatically detected
using an information-augmented active shape model on the
diagnostic images. This can assist the clinicians in quickly
defining slices with standardized and reproducible orientation, thus increasing diagnostic accuracy and also comparability of serial examinations. The method has been evaluated
on 42 knee MR images. It has the potential to be incorporated into existing systems because it does not change the
current acquisition protocol.
