5.3.6.1 Human Knee
The generation of the knee model was based on a total number of 112 MR-images,
taken sagittally, with a slice thickness of 1.0 mm, cf. Fig.
5.58
, (Harchafe 2010).
In Fig.
5.59
, the transversal MR-images show the complexity of the required
selection of anatomical structures. Image reconstruction was conducted with
image reconstruction software (e.g. M
IMICS
), and the reconstructed surface infor-
mation was further processed using appropriate graphic tools (e.g. G
EOMAGIC
)as
illustrated in Fig.
