Converting 3D to 4D images and vise versa
To convert 3D images to 4D images
1 Open a 3D image or image dataset.
2 Select Utilities > Convert 3D to 4D. The Convert 3D to 4D dialog box opens.
3 Do either of the following in the Number of slices in the 3rd dimension, Resolutions: 3rd dimension, and Resolutions: 4th dimension boxes:
- Accept the default numbers.
- Enter different numbers.
4 Select in each of the Resolution units: 3rd dimension and Resolutions units: 4th dimension lists one of the following: millimeters (the default value), unknown, inches, centimeters, angstroms, nanometers, micrometers, milliliters, meters, kilometers, miles, nanoseconds, microseconds, milliseconds, seconds, minutes, hours, or Hz.
5 Click OK. The program applies all of the specification in this dialog box to the image or image dataset. See Figure 1.
Number of slices in the 3rd dimension
|
Specifies how many slices are in the 3rd dimension. The default number is 2.
|
|
Resolutions:
3rd dimension |
Indicates the resolution for the third dimension. The default number is 5.0.
| |
Resolutions:
4th dimension |
Indicates the resolution for the fourth dimension. The default number is 1.0.
| |
Resolution units:
3rd dimension |
Indicates the voxel resolution in the 3rd dimension.
| |
Resolution units:
4th dimension |
Indicates the voxel resolution of the 4th dimension.
| |
OK
|
Applies the specified parameters to convert a 3D image to a 4D image.
| |
Cancel
|
Disregards any changes you made in this dialog box, closes the dialog box, and does not convert the image.

To convert 4D to 3D images
1 Open a 4D image or image dataset.
2 Select Utilities > Convert 4D to 3D.
The program immediately begins processing the image.
Extracting 3D subset from 4D
This utility allows you to remove one of the 'x, y, z, or dimensions from 4D images to produce a 3D image. Refer to Figure 2.
To remove an X dimension slice
1 Open a 4D image.
2 Select Utilities >4D Tools> Extract 3D Subset from 4D. The Extract 3D Subset dialog box (Figure 2) opens.
3 Select X.
4 Type the index number of the slice you want to extract in the Select index from. <N > to <N > box.
5 Click Remove. The program removes the slice you specified from the dataset.
To remove a Y dimension slice
1 Open a 4D image.
2 Select Utilities > Extract 3D Subset from 4D. The Extract 3D Subset dialog box (Figure 2) opens.
3 Select Y.
4 Type the index number of the slice you want to extract in the
Select index from <N > to <N > box.
5 Type the index number of the slice you want to extract in the Select index from. <N > to <N > box.
6 Click Remove. The program removes the slice you specified from the dataset.
To remove a Z dimension slice
1 Open a 4D image.
2 Select Utilities > Extract 3D Subset from 4D. The Extract 3D Subset dialog box (Figure 2) opens.
3 Select Z.
4 Type the index number of the slice you want to extract in the Select index from. <N > to <N > box.
5 Click Remove. The program removes the slice you specified from the dataset.
To remove the T dimension
1 Open a 4D image.
2 Select Utilities > Extract 3D Subset from 4D. The Extract 3D Subset dialog box (Figure 2) opens.
3 Select T.
4 Type the index number of the slice you want to extract in the Select index from. <N > to <N > box.
5 Click Remove. The program removes the slice you specified from the dataset.
X
|
Specifies that the algorithm should remove the X (width) dimension.
|
|
Y
|
Specifies that the algorithm should remove the Y (height, or length) dimension.
| |
Z
|
Specifies that the algorithm should remove the Z (depth) dimension.
| |
T
|
Specifies that the T (time) dimension should be removed.
| |
Index from <N> to <N>
|
Specifies the index number of the volume or slice that you want to extract from the dataset.
| |
Extract
|
Removes the specified dimension.
| |
Cancel
|
Disregards any changes you made in this dialog box, closes the dialog box, and does not remove any dimensions.

Removing time volumes
Swapping the third and fourth dimensions
Because MIPAV requires that datasets be stored using the xyzt method, it provides the Swap Dims 3 <-> 4 command for those users whose datasets may be stored using the xytz method.
Select all
|
Selects all time volumes.
|
|
Clear
|
Clears selection.
| |
Remove
|
Removes selected slices.
| |
Cancel
|
Disregards any changes you made in this dialog box, closes the dialog box, and does not remove the time volumes.
