Applicator-based registration (tandem-ring)
manual: landmark definition based on applicator points
automatic: volumetric images with reconstructed applicators (3D models)
If we know where the applicator
is, we can define reproducible
image registration points using
the
applicator
as a r
eference
coordinate system
in all kinds
of images!
