volume have to be measured. Hence equation 3.36 amplifies to
v(x ijk , s m , t n ) = v(x i , y j , z k , s m , t n ) =
(3.37)
(v x (x i , y j , z k , s m , t n ), v y (x i , y j , z k , s m , t n ), v z (x i , y j , z k , s m , t n )),
for a spacial localization x ijk , a slice indicator s m and a time step t n .
3.5.2 Data Acquisition
The datasets used for experiments in section 6 were acquired from healthy subjects,
figure 3.5 with two 1.5 Tesla MRI systems (Magnetom Sonanta, Siemens, at the radiology
department at the Landesklinikum Graz and Magnetom Espree, Siemens at the
Diagnostikzentrum Graz).
Measuring a complete exam, as described in the previous sections takes between
10 and 35 minutes with temporarily given instructions to the subject to suspend respiration.
The resulting image set is outlined in figure 3.17. The data can be accessed
directly via the installed PACS 1 or exported and stored on various data carriers in the
well known DICOM 2 file format.
