Hello,
It sounds like you would want to make use of the 3D Parametric Surface VI that ships with the LabVIEW Full Development and Professional Development systems. This VI is part of the Graphics and Sound palette that installs with those packages. Unfortunately, no algorithm has been developed by NI for building a 3D image from 2-D slices. The 3D Parametric Surface VI has three inputs (X Matrix, Y Matrix, and Z Matrix) that are used to construct and display a 3D image. There are several examples that ship with LabVIEW that demonstrate how you can use this function. These examples can be found by opening the NI Example Finder and searching for "3D." I would suggest starting with these VIs.
As another option, you could perhaps build an array of images and then have a control on your front panel that would allow you to control the image index that you are currently showing on your image display. You would still only be viewing a single image at a time, but you would at least have the ability to view two dimensions of the overall image at a time and then iterate through the third axis. You could also try converting each image into a 2D array and then building a 3D array of pixel intensities. You could then easily rotate the array in 90 degree increments and build a new image based upon the rotation and a depth that you could specify with a slider or numeric control. Rotating at any degree increments other than 90 degrees would require development of an interpolation algorithm.
Try looking at those shipping examples and implementing the 3D array that I described above. Let me know if you have any additional questions.
