see the 3d image and see the coordinates while moving the mouse over the image

I have a nii binary medical image. How can I visualize it in a way that I be able to move my mouse over it and see the coordinates I am moving over?

Or how can I visualize some specific points in the format of ijk on the image also?

You can use imshow() to display any particular slice of the image and then use the axis datatip button to get the in-slice 2D coordinates of particular pixels.

It is not mathematically possible to have a 3D datatip on a 2D rendering of 3D space (although the dataip will work on a surface plot).
