In-Depth Information
package covers the registered voxelized source data as well as surface and vol-
ume tessellations. In [28] a method for reconstructing 3D atlases from digital
2D atlas diagrams is presented. Tracer-specific templates were created in [11]
using small-animal PET data mapped onto a 3D MRI rat brain template
which is oriented according to the rat brain Paxinos atlas.
Apart from quantitative algorithm validation there is a great demand for
atlas and phantom based methods, e.g., in atlas-based attenuation correc-
tion [29, 44] and PVC [58].
In conclusion, to reliably validate new image processing methods it is es-
sential to take advantage of hardware or software phantoms. The ground-truth
information provided by phantoms is often compared to the methods' results
using intensity based measures.
