Regularize Z Spacing

Group (Subgroup)

Sampling Filters (Resolution)

Description

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
00
13
27
312
414
519
624
725
830
934

and the user wanted a uniform resolution of 3, then the following mapping woud occur

New Slice # New Slice Location Old Slice # Used
000
131
262
392
4123
5154
6185
7215
8246
9277
10308
11339

Note: there is no interpolation of the data and the nearest "old slice" is copied to a given "new slice".
