Fig 
In the Figure 5, brain surface has been defined as translucent 
and the tumour surface is opaque. Thus, it is possible to see 
brain and tumour together. Here skin model had been obtained 
from CT slices and the others from MR slices. Brain and 
tumour surface models have been registered with 3D affine 
mapping. 
In Figure 6, photo realistic skin surface model after texture 
mapping is shown from different angles.

7. CONCLUSION 
By using 3D models, it is easy to diagnose pathological 
formations and preparing the treatment plans. With 3D models, 
it will be possible to trace the progress of the diseases. Thus, for 
many diseases such as Parkinson, new treatment methods may 
be developed. On the other hand, a such system may be used in 
plastic surgery or in dental diagnosis and treatments. 
When the medical imaging and photogrammetry get closer, it 
would be possible to produce new approaches and techniques 
for medical purposes. By considering the photogrammetric 
methods in medical imaging, some progressed changes would 
be obtained on designing medical image acquisition and 
evaluation systems.
