How to customize data cursor?

I have 160 slices od mri. I need to take 3D point from 2D slice in such way that data cursor takes x and y coordinates from 2D image and z coordinate to take from slice position along the z axes, which is displayed in textbox.

OR, to show this 2D slice in 3D axes and set the angle view from above (90°) to seems like 2D axes, and then the cursor would take the x, y, and z coordinate. How to achive that?

Thanks.
