Sampling Filters (Resolution)
This filter "resamples" the 3D array in the Z-direction (which is generally taken as the setioning direction). The Voxel data container assumes all Cells are of the same size. If the Z locations (i.e. slice positions) are not uniform, then the user can enter a list of the actual Z locations and a desired uniform "resolution". The filter will then create a new volume with uniform Z locations and determine which of the old "slices" should be copied to the new "slices". Below is an example:
If a dataset had 10 sections with the following locations:
Old Slice # | Old Slice Location |
---|---|
0 | 0 |
1 | 3 |
2 | 7 |
3 | 12 |
4 | 14 |
5 | 19 |
6 | 24 |
7 | 25 |
8 | 30 |
9 | 34 |
and the user wanted a uniform resolution of 3, then the following mapping woud occur
New Slice # | New Slice Location | Old Slice # Used |
---|---|---|
0 | 0 | 0 |
1 | 3 | 1 |
2 | 6 | 2 |
3 | 9 | 2 |
4 | 12 | 3 |
5 | 15 | 4 |
6 | 18 | 5 |
7 | 21 | 5 |
8 | 24 | 6 |
9 | 27 | 7 |
10 | 30 | 8 |
11 | 33 | 9 |
Note: there is no interpolation of the data and the nearest "old slice" is copied to a given "new slice".
