Internally, (X)MedCon uses a dimension layout similar to the Analyze (SPM) format: an array dim[8] with a limited number of possible dimensions, linked by nested for-loops:
for ( energy_windows < dim[7] )
for ( detector_heads < dim[6] )
for ( R-R intervals < dim[5] )
for ( time_slots < dim[4] )
for ( slices < dim[3] )
{
/* do something on each stored image */
}
This results in two major limitations:
- the maximum number of volume dimensions = five.
Note that for GATED TOMO in DICOM, six dimensions are needed. However, the number of rotations must be equal to one.
- only symmetric files allowed. Each dimension requires an equal amount of images.
(X)MedCon dislikes any embedded (stupid) preview slices. Asymmetric volume files will be stored as one-dimensional; issued with a warning.
And did we mention it yet? This layout is core stuff for the library.
